+
+# 稳定 URL
+
+在 NocoBase 中，由存储引擎托管的文件会通过**稳定 URL（Stable URL）**访问。这个地址先进入 NocoBase，再由 NocoBase 检查文件记录和访问权限，最后重定向到存储引擎生成的实际地址。
+
+## URL 格式
+
+文件记录返回的地址通常是：
+
+```text
+/files/<app>/<dataSource>/<collection>/<id><extname>
+```
+
+比如：
+
+```text
+/files/main/main/attachments/42.pdf
+```
+
+如果 NocoBase 配置了 `APP_PUBLIC_PATH=/nocobase`，地址会自动带上该前缀：
+
+```text
+/nocobase/files/main/main/attachments/42.pdf
+```
+
+其中：
+
+- `app` 是应用名称
+- `dataSource` 是数据源标识
+- `collection` 是附件表或文件表名称
+- `id` 是文件记录的 ID
+- `extname` 是文件扩展名，没有扩展名时不会追加
+
+文件创建后，`id` 和 `extname` 不允许修改，因此同一条文件记录的地址可以保持稳定。
+
+## 不同用途的地址
+
+同一条文件记录会根据用途使用不同的 query 参数：
+
+| 用途 | 地址形式 | 表现 |
+|---|---|---|
+| 打开或内嵌文件 | `/files/.../42.pdf` | 检查权限后重定向到文件实际地址 |
+| 预览图片等内容 | `/files/.../42.png?preview=1` | 检查权限后重定向到存储引擎的预览地址；存储引擎支持缩略图规则时会使用缩略图 |
+| 下载文件 | `/files/.../42.pdf?download=1` | 检查权限后返回带下载语义的实际地址 |
+| Office 在线预览 | `/files/.../42.xlsx?temporaryAccessToken=...` | 供 Microsoft Office Online Viewer 短期读取，不作为普通文件地址保存 |
+
+:::tip
+
+业务代码通常只需要使用接口返回的 `url` 和 `preview`，不需要自己拼接 `/files` 地址或 query 参数。
+
+:::
+
+## 在各个地方的表现
+
+### 附件字段和文件表
+
+附件字段与文件表中的系统托管文件，上传、查询和关联读取后返回的 `url` 都是稳定 URL，`preview` 则是在同一地址上增加 `preview=1`。
+
+图片、PDF、音视频和文本等文件仍可在 NocoBase 中预览。刚上传的本地图片会优先使用浏览器生成的临时本地预览，数据重新读取后再使用稳定 URL，避免上传完成时出现重复请求或缩略图闪烁。
+
+### HTTP API
+
+通过 [HTTP API](./http-api.md) 上传或查询文件时，响应中的 `url` / `preview` 不再暴露本地路径、对象存储域名或预签名下载地址。调用方访问稳定 URL 时需要携带对应应用的登录凭证。
+
+稳定 URL 返回 `302` 重定向，不直接代理文件流。如果使用 `curl` 等客户端读取文件内容，需要允许跟随重定向：
+
+```bash
+curl -L \
+  -H "Authorization: Bearer <JWT>" \
+  "https://example.com/files/main/main/attachments/42.pdf"
+```
+
+浏览器直接打开文件时通常使用登录 cookie。`GET` 和 `HEAD` 可以访问稳定 URL，其他 HTTP 方法会返回 `405`。
+
+### Markdown 编辑器
+
+在 Markdown 编辑器中上传文件后，写入 Markdown 内容的是稳定 URL。私有 S3、OSS、COS 或 S3 Pro 存储也可以使用这种方式，不需要把存储空间调整为公开读取。
+
+如果 Markdown 内容会展示在未登录页面，那么查看者仍需要拥有文件查看权限。仅把稳定 URL 写入 Markdown，不会自动把文件公开。
+
+### 附件 URL 字段
+
+附件 URL 字段上传到 NocoBase 存储引擎后，字段中保存的是稳定 URL。图片缩略图会使用对应的 `preview` 地址。
+
+如果字段保存的是手工输入的外部 URL，并且文件记录没有 `storageId`，NocoBase 会继续保留并返回原始外部 URL。这类文件不经过稳定 URL 的权限检查和重定向流程。
+
+### 普通文件预览
+
+图片、PDF、音频、视频和文本预览会直接使用稳定 URL。浏览器请求会携带 NocoBase 登录 cookie，再按当前角色检查附件表或文件表的 `get/view` 权限。
+
+对于对象存储中的 PDF 等文件，最终预览方式还会受到存储服务 CORS 配置的影响。如果自定义前端通过 `fetch()` 读取重定向后的对象存储地址，也需要确保对象存储允许当前站点跨域访问。
+
+### Office 文件预览
+
+Microsoft Office Online Viewer 由 Microsoft 服务端拉取文件，无法携带用户浏览器中的 NocoBase cookie。因此，用户真正打开 Office 预览时，NocoBase 会先检查该文件的查看权限，再签发一个短期临时 URL。
+
+临时 URL 默认有效 10 分钟，可以通过 `TEMPORARY_FILE_ACCESS_EXPIRES_IN` 配置为 5 到 10 分钟。它只绑定当前文件，过期后无法继续使用。重新打开预览时会重新申请，加载失败时预览器也可能重新申请一次。
+
+:::warning 注意
+
+临时 URL 只用于外部预览服务读取文件。不要把它写回附件字段、Markdown 或业务表，也不要把它当成长期分享链接。
+
+:::
+
+### 公开表单
+
+访客在公开表单中上传文件后，NocoBase 会在当前公开表单会话中记录这些文件。上传者可以继续看到自己刚上传的图片或附件。
+
+这个访问范围只服务于当前公开表单会话，并不是通用的公开文件链接。把地址复制到其他浏览器或当前会话失效后，仍可能无法访问。
+
+## 权限和重定向
+
+访问稳定 URL 时，NocoBase 会按照 URL 中的应用、数据源、文件表和记录 ID 定位文件。其中：
+
+1. 已登录用户使用当前应用的登录 cookie 或认证信息，并检查当前角色的文件查看权限。
+2. 公开表单等插件可以对特定文件提供额外的受限授权。
+3. 检查通过后，NocoBase 返回 `302`，跳转到本地存储或对象存储生成的实际地址。
+
+因此，稳定 URL 隔离了业务数据和存储实现。切换存储域名、更新对象存储签名或调整缩略图规则时，业务字段中保存的地址通常不需要跟着修改。
+
+## 使用注意
+
+- 稳定不等于公开。复制链接给其他人后，对方仍需要登录并拥有文件查看权限
+- 稳定不等于永不失效。删除文件记录、删除文件、变更应用或数据源标识、移动到另一张文件表后，原地址会失效
+- 不要持久化 `temporaryAccessToken`。它是短期凭证，也可能进入浏览器历史和访问日志
+- 不要缓存 `302 Location` 作为永久地址。对象存储签名可能过期，应该每次从稳定 URL 重新解析
+- 不要自行替换 URL 中的 `app`、`dataSource`、`collection`、`id` 或扩展名。路径与文件记录不一致时会被拒绝
+- 反向代理需要把 `APP_PUBLIC_PATH` 下的 `/files/` 路径转发到 NocoBase。使用子路径部署时，还应保留根路径 `/files/` 的兼容转发规则。使用 NocoBase CLI 生成的代理配置时会自动包含这些规则
+- 页面跨源访问 API 的部署（配置了指向其他源的 `API_BASE_URL`）需要把页面来源加入 `CORS_ORIGIN_WHITELIST`，否则登录 cookie 无法写入，稳定 URL 会因缺少凭证返回 `403`，详见[环境变量](../get-started/installation/env.md#api_base_url)
+- 部署多个彼此独立的 NocoBase 服务时，应为每个服务使用不同的 `hostname`，不要只通过端口区分。浏览器 cookie 不按端口隔离，详细说明见[生产环境部署](../get-started/deployment/production.md)
+- 同一个 NocoBase 部署环境内的子应用会按应用名区分 cookie，不需要单独配置 `hostname`；不过另一个端口上的独立服务如果包含同名主应用或子应用，仍需要通过不同的 `hostname` 隔离
+- 如果通过 `<img>`、`<iframe>`、`fetch()` 或第三方客户端访问文件，需要确认它会携带凭证，并能跟随 `302` 重定向
+- 真正需要长期对外分享文件时，应使用专门的分享或公开访问方案，不要把稳定 URL 或 Office 临时 URL 当成分享链接

 在生产环境中部署 NocoBase 时，由于不同系统和环境的构建方式存在差异，安装依赖可能较为繁琐。为获得完整功能体验，我们推荐使用 **Docker** 进行部署。如果系统环境无法使用 Docker，也可以使用 **create-nocobase-app** 进行部署。
 
-:::warning
+:::warning 注意
 
 不建议直接在生产环境中使用源码部署。源码依赖较多、体积庞大，且全量编译对 CPU 和内存要求较高。如果确实需要使用源码部署，建议先构建自定义 Docker 镜像，再进行部署。
 
 :::
 
+:::warning 注意
+
+如果要部署多个彼此独立的 NocoBase 服务，请为每个服务使用不同的 `hostname`（比如不同的子域名），不要只通过端口区分服务，如 `https://example.com:13000` 和 `https://example.com:14000`。
+
+NocoBase 会使用 cookie 维持登录状态和[文件访问权限](../../file-manager/stable-url.md)。浏览器发送 cookie 时不会按端口隔离，同一 `hostname` 下不同端口的服务可能共享同名 cookie，导致登录状态互相覆盖，或出现文件预览、下载鉴权失败等问题。
+
+同一个 NocoBase 部署环境内的子应用不在这个限制范围内。登录 cookie 会按应用名区分，主应用和不同名称的子应用可以共享同一个 `hostname`。
+
+不过不能据此忽略独立服务之间的隔离。如果在同一 `hostname` 的另一个端口运行了另一个 NocoBase 服务，并且其中存在同名主应用或子应用，cookie 仍可能冲突。
+
+推荐分别使用 `app1.example.com` 和 `app2.example.com`，再通过 Nginx 或 Caddy 反向代理到不同的 NocoBase 服务。
+
+:::
+
+## 前后端分离 / 跨源访问 API
+
+推荐让页面和 API 保持同源：通过同一域名下的反向代理，把 `${APP_PUBLIC_PATH}api/` 和 `${APP_PUBLIC_PATH}files/` 转发到 NocoBase 服务，`API_BASE_URL` 留空。
+
+如果页面必须跨源访问 API（配置了指向其他源的 `API_BASE_URL`），需要把页面来源加入 `CORS_ORIGIN_WHITELIST`，否则浏览器会忽略 API 响应中的 `Set-Cookie`，登录 cookie 无法写入，文件稳定 URL 的预览和下载会鉴权失败。
+
+同时注意 cookie 按 `hostname` 存储：页面与 API 域名完全不同时，从页面域名访问 `/files/` 不会携带 API 域名下的登录 cookie，这类部署应改为同源反向代理。详见[环境变量](../installation/env.md#api_base_url)。

+keywords: "stabile URL,Proxy-URL,permanente URL,Dateizugriff,Office-Vorschau,NocoBase"
+---
+
+# Stabile URL
+
+Dateien, die von einer NocoBase-Speicher-Engine verwaltet werden, sind über eine **stabile URL** erreichbar. NocoBase prüft zuerst den Dateidatensatz und die Berechtigungen und leitet anschließend zur tatsächlichen Speicher-URL weiter.
+
+## Format
+
+```text
+/files/<app>/<dataSource>/<collection>/<id><extname>
+```
+
+Bei `APP_PUBLIC_PATH=/nocobase` beginnt der Pfad mit `/nocobase/files/`. ID und Erweiterung können nach dem Erstellen nicht geändert werden. Daher bleibt die URL stabil, solange der Datensatz existiert.
+
+| Zweck | URL | Verhalten |
+|---|---|---|
+| Öffnen | `/files/.../42.pdf` | Prüft die Berechtigung und leitet zur Datei weiter |
+| Vorschau | `/files/.../42.png?preview=1` | Leitet zur Vorschau oder Miniaturansicht weiter |
+| Download | `/files/.../42.pdf?download=1` | Leitet mit Download-Semantik weiter |
+| Office | `/files/.../42.xlsx?temporaryAccessToken=...` | Kurzzeitiger Zugriff für Office Online Viewer |
+
+## Verhalten in NocoBase
+
+- Anhangsfelder, Dateitabellen und die [HTTP API](./http-api.md) geben stabile URLs in `url` und `preview` zurück
+- Markdown speichert die stabile URL und unterstützt private S3-, OSS-, COS- und S3-Pro-Speicher
+- Das Anhang-URL-Feld behält manuell eingegebene externe URLs bei und verwendet für verwaltete Uploads die stabile URL
+- Normale Vorschauen verwenden die aktuelle NocoBase-Sitzung und die Dateiberechtigungen
+- Öffentliche Formulare gewähren nur begrenzten Zugriff auf Dateien, die in der aktuellen Formularsitzung hochgeladen wurden
+
+## Office-Vorschau
+
+Microsoft Office Online Viewer kann das NocoBase-Cookie des Benutzers nicht verwenden. Beim Öffnen prüft NocoBase zuerst die Berechtigung und stellt dann eine temporäre, an die Datei gebundene URL aus. Sie gilt standardmäßig 10 Minuten und kann mit `TEMPORARY_FILE_ACCESS_EXPIRES_IN` auf 5 bis 10 Minuten eingestellt werden.
+
+Speichere diese URL nicht in Feldern, Markdown oder Geschäftsdaten und verwende sie nicht als Freigabelink.
+
+## Hinweise
+
+- Stabil bedeutet nicht öffentlich; der Empfänger benötigt weiterhin eine Berechtigung
+- Löschen oder Verschieben des Datensatzes macht die alte URL ungültig
+- Die Antwort ist eine `302`-Weiterleitung, der Clients folgen müssen
+- `302 Location` und `temporaryAccessToken` dürfen nicht dauerhaft gespeichert werden
+- Der Reverse Proxy muss `/files/` unter `APP_PUBLIC_PATH` an NocoBase weiterleiten. Bei einer Bereitstellung unter einem Unterpfad sollte zusätzlich die kompatible Route `/files/` auf Root-Ebene erhalten bleiben. Von der NocoBase CLI erzeugte Konfigurationen enthalten beide Regeln automatisch
+- Bei Bereitstellungen, bei denen Seiten die API ursprungsübergreifend aufrufen (`API_BASE_URL` zeigt auf einen anderen Origin), muss der Seiten-Ursprung zu `CORS_ORIGIN_WHITELIST` hinzugefügt werden. Andernfalls wird das Anmelde-Cookie nie gespeichert und stabile URLs liefern wegen fehlender Anmeldeinformationen `403`. Siehe [Umgebungsvariablen](../get-started/installation/env.md#api_base_url)
+- Verwende für jeden unabhängigen NocoBase-Dienst einen eigenen `hostname`, statt die Dienste nur durch Ports zu unterscheiden. Browser-Cookies werden nicht nach Port getrennt; weitere Informationen findest du unter [Bereitstellung in einer Produktionsumgebung](../get-started/deployment/production.md)
+- Unteranwendungen innerhalb derselben NocoBase-Bereitstellung werden anhand des Anwendungsnamens unterschieden und benötigen keine eigenen Hostnames. Ein unabhängiger Dienst auf einem anderen Port muss jedoch weiterhin über einen eigenen Hostname isoliert werden, wenn er eine Haupt- oder Unteranwendung mit demselben Namen enthält

 Wenn Sie NocoBase in einer Produktionsumgebung bereitstellen, kann die Installation von Abhängigkeiten aufwendig sein, da die Build-Methoden in verschiedenen Systemen und Umgebungen variieren. Für ein vollständiges Funktionserlebnis empfehlen wir die Bereitstellung mit **Docker**. Wenn Ihre Systemumgebung Docker nicht verwenden kann, können Sie auch **create-nocobase-app** für die Bereitstellung nutzen.
 
-:::warning
+:::warning Hinweis
 
 Es wird nicht empfohlen, NocoBase direkt aus dem Quellcode in einer Produktionsumgebung bereitzustellen. Der Quellcode hat viele Abhängigkeiten, ist umfangreich und eine vollständige Kompilierung stellt hohe Anforderungen an CPU und Arbeitsspeicher. Wenn Sie unbedingt aus dem Quellcode bereitstellen müssen, wird empfohlen, zuerst ein benutzerdefiniertes Docker-Image zu erstellen und es dann bereitzustellen.
 
 :::
 
+:::warning Hinweis
+
+Wenn Sie mehrere voneinander unabhängige NocoBase-Dienste bereitstellen, verwenden Sie für jeden Dienst einen eigenen `hostname`, etwa unterschiedliche Subdomains. Unterscheiden Sie die Dienste nicht nur über Ports wie `https://example.com:13000` und `https://example.com:14000`.
+
+NocoBase verwendet Cookies für den Anmeldestatus und die [Dateizugriffsrechte](../../file-manager/stable-url.md). Browser trennen Cookies nicht nach Port. Dienste auf verschiedenen Ports unter demselben `hostname` können daher gleichnamige Cookies gemeinsam verwenden, wodurch Anmeldestatus überschrieben oder die Autorisierung von Dateivorschau und Download beeinträchtigt werden kann.
+
+Unteranwendungen innerhalb derselben NocoBase-Bereitstellung fallen nicht unter diese Einschränkung. Anmelde-Cookies werden anhand des Anwendungsnamens unterschieden, sodass die Hauptanwendung und unterschiedlich benannte Unteranwendungen denselben `hostname` verwenden können.
+
+Unabhängige Dienste müssen dennoch isoliert werden. Wenn ein weiterer NocoBase-Dienst auf einem anderen Port unter demselben `hostname` läuft und eine gleichnamige Haupt- oder Unteranwendung enthält, können die Cookies weiterhin kollidieren.
+
+Verwenden Sie beispielsweise `app1.example.com` und `app2.example.com` und leiten Sie diese über Nginx oder Caddy an die jeweiligen NocoBase-Dienste weiter.
+
+:::
+
+## Getrenntes Frontend / Ursprungsübergreifender API-Zugriff
+
+Es ist empfehlenswert, Seiten und API auf demselben Origin zu halten: Verwenden Sie einen Reverse-Proxy unter derselben Domain, der `${APP_PUBLIC_PATH}api/` und `${APP_PUBLIC_PATH}files/` an den NocoBase-Dienst weiterleitet, und lassen Sie `API_BASE_URL` leer.
+
+Wenn die Seiten die API ursprungsübergreifend aufrufen müssen (`API_BASE_URL` zeigt auf einen anderen Origin), fügen Sie den Ursprung der Seiten zu `CORS_ORIGIN_WHITELIST` hinzu. Andernfalls ignoriert der Browser `Set-Cookie` in API-Antworten, das Anmelde-Cookie wird nicht gespeichert und Vorschau sowie Download über stabile Datei-URLs schlagen bei der Autorisierung fehl.
+
+Beachten Sie außerdem, dass Cookies pro `hostname` gespeichert werden: Wenn Seiten und API vollständig unterschiedliche Domains verwenden, enthalten Aufrufe von `/files/` über die Seitendomain nicht das Anmelde-Cookie, das unter der API-Domain gespeichert wurde. Solche Bereitstellungen sollten auf einen Same-Origin-Reverse-Proxy umgestellt werden. Siehe [Umgebungsvariablen](../installation/env.md#api_base_url).

+keywords: "stable URL,proxy URL,permanent URL,file access,file permissions,Office preview,NocoBase"
+---
+
+# Stable URL
+
+Files managed by a NocoBase storage engine are accessed through a **stable URL**. The URL first reaches NocoBase, where the file record and access permissions are checked, and then redirects to the actual URL generated by the storage engine.
+
+## URL format
+
+```text
+/files/<app>/<dataSource>/<collection>/<id><extname>
+```
+
+For example:
+
+```text
+/files/main/main/attachments/42.pdf
+```
+
+When `APP_PUBLIC_PATH=/nocobase` is configured, the URL starts with `/nocobase/files/`. The path identifies the app, data source, file collection, record ID, and extension. The ID and extension cannot be changed after creation, which keeps the URL stable for the lifetime of the record.
+
+## URL variants
+
+| Purpose | URL | Behavior |
+|---|---|---|
+| Open or embed | `/files/.../42.pdf` | Checks permission and redirects to the actual file URL |
+| Preview | `/files/.../42.png?preview=1` | Redirects to the preview or thumbnail URL |
+| Download | `/files/.../42.pdf?download=1` | Redirects with download semantics |
+| Office preview | `/files/.../42.xlsx?temporaryAccessToken=...` | Allows Microsoft Office Online Viewer to fetch one file for a short time |
+
+:::tip
+
+Use the `url` and `preview` values returned by NocoBase. Application code normally should not construct `/files` URLs or their query parameters.
+
+:::
+
+## Behavior across NocoBase
+
+- Attachment fields and file collections return stable URLs after upload and when records are queried
+- [HTTP API](./http-api.md) responses no longer expose local paths, storage domains, or presigned download URLs
+- Markdown uploads store the stable URL, including files in private S3, OSS, COS, or S3 Pro storage
+- Attachment URL fields store a stable URL for managed uploads, while manually entered external URLs remain unchanged
+- Image, PDF, audio, video, and text previews use the stable URL and the current NocoBase login session
+- Public forms grant limited access to files uploaded in the current public-form browser session; this does not create a generally public link
+
+## Office preview
+
+Microsoft Office Online Viewer fetches the file from Microsoft servers and cannot use the user's NocoBase cookie. When the user opens an Office preview, NocoBase first checks the user's file permission and then issues a temporary URL for that file.
+
+The URL is valid for 10 minutes by default. `TEMPORARY_FILE_ACCESS_EXPIRES_IN` may be set from 5 to 10 minutes. It is requested again when the preview is reopened and must never be saved in an attachment field, Markdown content, or a business record.
+
+## Permissions and redirects
+
+Logged-in requests use the current app credentials and role. After permission is granted, NocoBase responds with `302` and redirects to the local or object-storage URL.
+
+Stable URLs support `GET` and `HEAD`. Other methods return `405`. A command-line client must follow redirects, for example:
+
+```bash
+curl -L \
+  -H "Authorization: Bearer <JWT>" \
+  "https://example.com/files/main/main/attachments/42.pdf"
+```
+
+## Important notes
+
+- Stable does not mean public; recipients still need permission to view the file
+- Deleting the record or changing its app, data source, or collection context invalidates the old URL
+- Do not persist `temporaryAccessToken` or use it as a sharing link
+- Do not cache the `302 Location` as a permanent URL because storage signatures can expire
+- Do not rewrite the app, data source, collection, ID, or extension in the path
+- Reverse proxies must forward the `/files/` route under `APP_PUBLIC_PATH` to NocoBase. For subpath deployments, keep a compatible root-level `/files/` route as well. Configurations generated by the NocoBase CLI include both routes automatically
+- Deployments where the pages access the API cross-origin (with `API_BASE_URL` pointing to another origin) must add the page origin to `CORS_ORIGIN_WHITELIST`; otherwise the login cookie is never stored and stable URLs return `403` for lack of credentials. See [Environment Variables](../get-started/installation/env.md#api_base_url)
+- Use a different `hostname` for each independent NocoBase service instead of separating services only by port. Browser cookies are not isolated by port; see [Production Environment Deployment](../get-started/deployment/production.md)
+- Sub-apps in the same NocoBase deployment are distinguished by app name and do not need separate hostnames. However, an independent service on another port still needs hostname isolation if it contains a main app or sub-app with the same name
+- Custom `fetch()` code may also need object-storage CORS after following the redirect
+- Use a dedicated sharing or public-access feature when a long-lived public link is required

 When deploying NocoBase in a production environment, installing dependencies can be cumbersome due to differences in build methods across various systems and environments. For a complete functional experience, we recommend deploying with **Docker**. If your system environment cannot use Docker, you can also deploy using **create-nocobase-app**.
 
-:::warning
+:::warning Note
 
 It is not recommended to deploy directly from source code in a production environment. The source code has many dependencies, is large in size, and a full compilation has high CPU and memory requirements. If you must deploy from source code, it is recommended to first build a custom Docker image and then deploy it.
 
 :::
 
+:::warning Note
+
+If you deploy multiple independent NocoBase services, use a different `hostname` for each service, such as separate subdomains. Do not distinguish services only by port, for example `https://example.com:13000` and `https://example.com:14000`.
+
+NocoBase uses cookies to maintain login state and [file access permissions](../../file-manager/stable-url.md). Browsers do not isolate cookies by port, so services on different ports under the same `hostname` may share cookies with the same name. This can overwrite login state or cause file preview and download authorization failures.
+
+Sub-apps within the same NocoBase deployment are outside this restriction. Login cookies are distinguished by app name, so the main app and differently named sub-apps can share one `hostname`.
+
+However, independent services still need isolation. If another NocoBase service runs on a different port under the same `hostname` and contains a main app or sub-app with the same name, its cookies may still conflict.
+
+Use addresses such as `app1.example.com` and `app2.example.com`, then route them to different NocoBase services through Nginx or Caddy.
+
+:::
+
+## Separated Frontend / Cross-Origin API Access
+
+Prefer keeping the pages and the API on the same origin: use a reverse proxy under one domain to forward `${APP_PUBLIC_PATH}api/` and `${APP_PUBLIC_PATH}files/` to the NocoBase service, and leave `API_BASE_URL` empty.
+
+If the pages must access the API cross-origin (with `API_BASE_URL` pointing to another origin), add the page origin to `CORS_ORIGIN_WHITELIST`. Otherwise the browser ignores `Set-Cookie` in API responses, the login cookie is never stored, and preview and download through stable file URLs fail authorization.
+
+Also note that cookies are stored per `hostname`: when the pages and the API use entirely different domains, requests to `/files/` from the page domain will not carry the login cookie stored under the API domain. Such deployments should switch to a same-origin reverse proxy. See [Environment Variables](../installation/env.md#api_base_url).

+Sub-apps within the same NocoBase deployment are distinguished by app name and do not need separate hostnames. However, if another independent NocoBase service runs on a different port under the same `hostname` and contains a main app or sub-app with the same name, its cookies may still conflict.
+
+For example, use `app1.example.com` and `app2.example.com` instead of `example.com:13000` and `example.com:14000`.

+keywords: "URL estable,URL proxy,URL permanente,acceso a archivos,vista previa de Office,NocoBase"
+---
+
+# URL estable
+
+Los archivos administrados por un motor de almacenamiento se abren mediante una **URL estable**. NocoBase comprueba el registro y los permisos, y después redirige a la URL real generada por el almacenamiento.
+
+## Formato
+
+```text
+/files/<app>/<dataSource>/<collection>/<id><extname>
+```
+
+Con `APP_PUBLIC_PATH=/nocobase`, la ruta comienza por `/nocobase/files/`. El ID y la extensión no pueden modificarse después de crear el archivo, por lo que la URL permanece estable mientras exista el registro.
+
+| Uso | URL | Comportamiento |
+|---|---|---|
+| Abrir | `/files/.../42.pdf` | Comprueba permisos y redirige al archivo |
+| Vista previa | `/files/.../42.png?preview=1` | Redirige a la miniatura o vista previa |
+| Descargar | `/files/.../42.pdf?download=1` | Redirige con semántica de descarga |
+| Office | `/files/.../42.xlsx?temporaryAccessToken=...` | Acceso temporal para Office Online Viewer |
+
+## Comportamiento en NocoBase
+
+- Los campos de adjuntos, las tablas de archivos y la [HTTP API](./http-api.md) devuelven la URL estable en `url` y `preview`
+- Markdown guarda la URL estable y admite almacenamiento privado S3, OSS, COS o S3 Pro
+- Un campo URL de adjunto conserva las URL externas introducidas manualmente, pero usa la URL estable para archivos administrados
+- Las vistas previas normales usan la sesión y los permisos actuales de NocoBase
+- Un formulario público solo permite ver los archivos subidos durante la sesión limitada de ese formulario
+
+## Vista previa de Office
+
+Microsoft Office Online Viewer no puede usar la cookie del usuario. Al abrir la vista previa, NocoBase comprueba primero el permiso y emite una URL temporal vinculada al archivo. Dura 10 minutos de forma predeterminada y puede configurarse entre 5 y 10 minutos con `TEMPORARY_FILE_ACCESS_EXPIRES_IN`.
+
+No guardes esa URL temporal en campos, Markdown ni datos de negocio, y no la uses como enlace compartido.
+
+## Precauciones
+
+- Estable no significa público; el destinatario todavía necesita permisos
+- Al eliminar o mover el registro a otro contexto, la URL anterior deja de funcionar
+- La respuesta es una redirección `302`; los clientes deben seguirla
+- No guardes `302 Location` ni `temporaryAccessToken`
+- El proxy inverso debe reenviar a NocoBase la ruta `/files/` situada bajo `APP_PUBLIC_PATH`. En despliegues bajo una subruta, también debe conservarse la ruta compatible `/files/` en la raíz. Las configuraciones generadas por la CLI de NocoBase incluyen ambas reglas automáticamente
+- En despliegues donde las páginas acceden a la API entre orígenes (`API_BASE_URL` apunta a otro origen), debes añadir el origen de la página a `CORS_ORIGIN_WHITELIST`. De lo contrario, la cookie de inicio de sesión nunca se almacenará y las URL estables devolverán `403` por falta de credenciales. Consulta [Variables de entorno](../get-started/installation/env.md#api_base_url)
+- Usa un `hostname` diferente para cada servicio NocoBase independiente, en vez de diferenciarlos únicamente por el puerto. Las cookies del navegador no se aíslan por puerto; consulta [Despliegue en producción](../get-started/deployment/production.md)
+- Las subaplicaciones de un mismo despliegue de NocoBase se distinguen por el nombre de la aplicación y no necesitan hostnames separados. Sin embargo, un servicio independiente en otro puerto sigue necesitando aislamiento por hostname si contiene una aplicación principal o subaplicación con el mismo nombre

 Al desplegar NocoBase en un entorno de producción, la instalación de dependencias puede ser complicada debido a las diferencias en los métodos de construcción entre distintos sistemas y entornos. Para una experiencia funcional completa, le recomendamos desplegarlo con **Docker**. Si su entorno de sistema no puede usar Docker, también puede desplegarlo utilizando **create-nocobase-app**.
 
-:::warning
+:::warning Atención
 
 No se recomienda desplegar directamente desde el código fuente en un entorno de producción. El código fuente tiene muchas dependencias, es de gran tamaño y una compilación completa exige altos requisitos de CPU y memoria. Si realmente necesita desplegar desde el código fuente, le sugerimos construir primero una imagen Docker personalizada y luego proceder con el despliegue.
 
 :::
 
+:::warning Atención
+
+Si despliega varios servicios NocoBase independientes, utilice un `hostname` diferente para cada servicio, como subdominios distintos. No diferencie los servicios únicamente por el puerto, por ejemplo `https://example.com:13000` y `https://example.com:14000`.
+
+NocoBase usa cookies para mantener el estado de inicio de sesión y los [permisos de acceso a archivos](../../file-manager/stable-url.md). Los navegadores no aíslan las cookies por puerto, por lo que los servicios en distintos puertos bajo el mismo `hostname` pueden compartir cookies con el mismo nombre. Esto puede sobrescribir el estado de inicio de sesión o provocar errores de autorización al previsualizar o descargar archivos.
+
+Las subaplicaciones del mismo despliegue de NocoBase no están sujetas a esta restricción. Las cookies de inicio de sesión se distinguen por el nombre de la aplicación, por lo que la aplicación principal y las subaplicaciones con nombres diferentes pueden compartir un mismo `hostname`.
+
+Sin embargo, los servicios independientes todavía deben aislarse. Si otro servicio NocoBase se ejecuta en otro puerto bajo el mismo `hostname` y contiene una aplicación principal o subaplicación con el mismo nombre, las cookies aún pueden entrar en conflicto.
+
+Utilice direcciones como `app1.example.com` y `app2.example.com`, y diríjalas a los distintos servicios NocoBase mediante Nginx o Caddy.
+
+:::
+
+## Frontend separado / Acceso API entre orígenes
+
+Se recomienda mantener las páginas y la API en el mismo origen: utilice un proxy inverso bajo el mismo dominio para reenviar `${APP_PUBLIC_PATH}api/` y `${APP_PUBLIC_PATH}files/` al servicio NocoBase, y deje `API_BASE_URL` vacío.
+
+Si las páginas deben acceder a la API entre orígenes (`API_BASE_URL` apunta a otro origen), añada el origen de la página a `CORS_ORIGIN_WHITELIST`. De lo contrario, el navegador ignorará `Set-Cookie` en las respuestas de la API, la cookie de inicio de sesión no se almacenará y la previsualización y descarga mediante URL de archivo estables fallarán en la autorización.
+
+Tenga en cuenta también que las cookies se almacenan por `hostname`: si las páginas y la API usan dominios completamente distintos, las solicitudes a `/files/` desde el dominio de la página no llevarán la cookie de inicio de sesión almacenada bajo el dominio de la API. En esos despliegues debe usarse un proxy inverso del mismo origen. Consulte [Variables de entorno](../installation/env.md#api_base_url).

+keywords: "URL stable,URL proxy,URL permanente,accès aux fichiers,aperçu Office,NocoBase"
+---
+
+# URL stable
+
+Les fichiers gérés par un moteur de stockage sont accessibles via une **URL stable**. NocoBase vérifie l'enregistrement et les autorisations, puis redirige vers l'URL réelle générée par le stockage.
+
+## Format
+
+```text
+/files/<app>/<dataSource>/<collection>/<id><extname>
+```
+
+Avec `APP_PUBLIC_PATH=/nocobase`, le chemin commence par `/nocobase/files/`. L'ID et l'extension ne peuvent pas être modifiés après la création, ce qui garde l'URL stable tant que l'enregistrement existe.
+
+| Usage | URL | Comportement |
+|---|---|---|
+| Ouvrir | `/files/.../42.pdf` | Vérifie les droits et redirige vers le fichier |
+| Aperçu | `/files/.../42.png?preview=1` | Redirige vers l'aperçu ou la miniature |
+| Télécharger | `/files/.../42.pdf?download=1` | Redirige avec une sémantique de téléchargement |
+| Office | `/files/.../42.xlsx?temporaryAccessToken=...` | Accès temporaire pour Office Online Viewer |
+
+## Comportement dans NocoBase
+
+- Les champs pièce jointe, les tables de fichiers et l'[HTTP API](./http-api.md) renvoient des URL stables dans `url` et `preview`
+- Markdown enregistre l'URL stable et prend en charge les stockages privés S3, OSS, COS et S3 Pro
+- Le champ URL de pièce jointe conserve les URL externes saisies manuellement et utilise l'URL stable pour les fichiers gérés
+- Les aperçus classiques utilisent la session et les autorisations NocoBase actuelles
+- Un formulaire public limite l'accès aux fichiers envoyés pendant la session actuelle du formulaire
+
+## Aperçu Office
+
+Microsoft Office Online Viewer ne peut pas utiliser le cookie NocoBase de l'utilisateur. À l'ouverture, NocoBase vérifie d'abord l'autorisation, puis émet une URL temporaire liée au fichier. Elle est valable 10 minutes par défaut et peut être réglée de 5 à 10 minutes avec `TEMPORARY_FILE_ACCESS_EXPIRES_IN`.
+
+N'enregistrez pas cette URL dans un champ, du Markdown ou des données métier, et ne l'utilisez pas comme lien de partage.
+
+## Précautions
+
+- Stable ne signifie pas public ; le destinataire a toujours besoin d'une autorisation
+- La suppression ou le déplacement de l'enregistrement invalide l'ancienne URL
+- La réponse est une redirection `302` que le client doit suivre
+- Ne conservez pas `302 Location` ni `temporaryAccessToken`
+- Le proxy inverse doit transmettre à NocoBase la route `/files/` située sous `APP_PUBLIC_PATH`. Pour un déploiement dans un sous-chemin, conservez également la route compatible `/files/` à la racine. Les configurations générées par la CLI NocoBase incluent automatiquement ces deux règles
+- Dans les déploiements où les pages accèdent à l'API en cross-origin (`API_BASE_URL` pointe vers une autre origine), vous devez ajouter l'origine des pages à `CORS_ORIGIN_WHITELIST`. Sinon, le cookie de connexion n'est jamais enregistré et les URL stables renvoient `403` faute d'identifiants. Voir [Variables d'environnement](../get-started/installation/env.md#api_base_url)
+- Utilisez un `hostname` différent pour chaque service NocoBase indépendant au lieu de les distinguer uniquement par leur port. Les cookies du navigateur ne sont pas isolés par port ; consultez [Déploiement en production](../get-started/deployment/production.md)
+- Les sous-applications d'un même déploiement NocoBase sont distinguées par leur nom d'application et ne nécessitent pas de hostnames séparés. Un service indépendant exécuté sur un autre port doit toutefois être isolé par hostname s'il contient une application principale ou une sous-application portant le même nom

 Lors du déploiement de NocoBase en environnement de production, l'installation des dépendances peut s'avérer complexe en raison des différentes méthodes de construction selon les systèmes et les environnements. Pour une expérience fonctionnelle complète, nous vous recommandons d'utiliser **Docker** pour le déploiement. Si votre environnement système ne permet pas l'utilisation de Docker, vous pouvez également déployer NocoBase avec **create-nocobase-app**.
 
-:::warning
+:::warning Attention
 
 Il n'est pas recommandé de déployer directement à partir du code source en environnement de production. Le code source comporte de nombreuses dépendances, est volumineux, et une compilation complète exige des ressources CPU et mémoire élevées. Si vous devez impérativement déployer à partir du code source, nous vous suggérons de construire d'abord une image Docker personnalisée, puis de la déployer.
 
 :::
 
+:::warning Attention
+
+Si vous déployez plusieurs services NocoBase indépendants, utilisez un `hostname` différent pour chaque service, par exemple des sous-domaines distincts. Ne distinguez pas les services uniquement par leur port, comme `https://example.com:13000` et `https://example.com:14000`.
+
+NocoBase utilise des cookies pour conserver l'état de connexion et les [autorisations d'accès aux fichiers](../../file-manager/stable-url.md). Les navigateurs n'isolent pas les cookies par port. Des services exécutés sur différents ports sous le même `hostname` peuvent donc partager des cookies portant le même nom, écraser l'état de connexion ou provoquer des échecs d'autorisation lors de l'aperçu et du téléchargement de fichiers.
+
+Les sous-applications d'un même déploiement NocoBase ne sont pas concernées par cette restriction. Les cookies de connexion sont distingués par le nom de l'application, de sorte que l'application principale et les sous-applications portant des noms différents peuvent partager un même `hostname`.
+
+Les services indépendants doivent toutefois rester isolés. Si un autre service NocoBase s'exécute sur un autre port sous le même `hostname` et contient une application principale ou une sous-application portant le même nom, les cookies peuvent encore entrer en conflit.
+
+Utilisez par exemple `app1.example.com` et `app2.example.com`, puis acheminez-les vers les différents services NocoBase avec Nginx ou Caddy.
+
+:::
+
+## Frontend séparé / Accès API cross-origin
+
+Il est recommandé de conserver les pages et l'API sur la même origine : utilisez un proxy inverse sous le même domaine pour transférer `${APP_PUBLIC_PATH}api/` et `${APP_PUBLIC_PATH}files/` vers le service NocoBase, et laissez `API_BASE_URL` vide.
+
+Si les pages doivent accéder à l'API en cross-origin (`API_BASE_URL` pointe vers une autre origine), ajoutez l'origine des pages à `CORS_ORIGIN_WHITELIST`. Sinon, le navigateur ignorera `Set-Cookie` dans les réponses de l'API, le cookie de connexion ne sera pas enregistré et l'aperçu ainsi que le téléchargement via les URL de fichiers stables échoueront à l'autorisation.
+
+Notez également que les cookies sont stockés par `hostname` : si les pages et l'API utilisent des domaines totalement différents, les requêtes vers `/files/` depuis le domaine des pages n'enverront pas le cookie de connexion stocké sous le domaine de l'API. Ce type de déploiement doit être remplacé par un proxy inverse same-origin. Voir [Variables d'environnement](../installation/env.md#api_base_url).

+---
+
+# URL stabil
+
+File yang dikelola oleh storage engine NocoBase diakses melalui **URL stabil**. NocoBase memeriksa record file dan izin akses, lalu mengalihkan permintaan ke URL aktual yang dibuat oleh storage engine.
+
+## Format
+
+```text
+/files/<app>/<dataSource>/<collection>/<id><extname>
+```
+
+Jika `APP_PUBLIC_PATH=/nocobase`, path dimulai dengan `/nocobase/files/`. ID dan ekstensi tidak dapat diubah setelah file dibuat, sehingga URL tetap stabil selama record masih ada.
+
+| Penggunaan | URL | Perilaku |
+|---|---|---|
+| Membuka | `/files/.../42.pdf` | Memeriksa izin dan mengalihkan ke file |
+| Pratinjau | `/files/.../42.png?preview=1` | Mengalihkan ke thumbnail atau URL pratinjau |
+| Unduh | `/files/.../42.pdf?download=1` | Mengalihkan dengan mode unduh |
+| Office | `/files/.../42.xlsx?temporaryAccessToken=...` | Akses sementara untuk Office Online Viewer |
+
+## Perilaku di NocoBase
+
+- Field attachment, file collection, dan [HTTP API](./http-api.md) mengembalikan URL stabil pada `url` dan `preview`
+- Markdown menyimpan URL stabil dan mendukung S3, OSS, COS, serta S3 Pro privat
+- Field URL attachment mempertahankan URL eksternal yang dimasukkan manual dan memakai URL stabil untuk upload yang dikelola NocoBase
+- Pratinjau biasa memakai sesi login dan izin file NocoBase saat ini
+- Form publik hanya memberi akses terbatas ke file yang diunggah dalam sesi form tersebut
+
+## Pratinjau Office
+
+Microsoft Office Online Viewer tidak dapat memakai cookie NocoBase milik pengguna. Saat pratinjau dibuka, NocoBase memeriksa izin terlebih dahulu lalu menerbitkan URL sementara yang terikat pada satu file. Masa berlaku default adalah 10 menit dan dapat diatur antara 5 sampai 10 menit melalui `TEMPORARY_FILE_ACCESS_EXPIRES_IN`.
+
+Jangan simpan URL sementara ini ke field, Markdown, atau data bisnis, dan jangan gunakan sebagai tautan berbagi.
+
+## Catatan penting
+
+- Stabil tidak berarti publik; penerima tetap memerlukan izin
+- Menghapus atau memindahkan record ke konteks lain akan membatalkan URL lama
+- Respons berupa pengalihan `302` yang harus diikuti oleh klien
+- Jangan menyimpan `302 Location` atau `temporaryAccessToken`
+- Reverse proxy harus meneruskan rute `/files/` di bawah `APP_PUBLIC_PATH` ke NocoBase. Untuk deployment pada subpath, pertahankan juga rute kompatibilitas `/files/` di root. Konfigurasi yang dibuat oleh NocoBase CLI otomatis mencakup kedua rute tersebut
+- Pada deployment ketika halaman mengakses API secara lintas origin (`API_BASE_URL` menunjuk ke origin lain), origin halaman harus ditambahkan ke `CORS_ORIGIN_WHITELIST`. Jika tidak, cookie login tidak akan pernah tersimpan dan stable URL akan mengembalikan `403` karena kredensial tidak ikut terkirim. Lihat [Variabel lingkungan](../get-started/installation/env.md#api_base_url)
+- Gunakan `hostname` yang berbeda untuk setiap layanan NocoBase yang berdiri sendiri, bukan hanya membedakannya berdasarkan port. Cookie browser tidak diisolasi berdasarkan port; lihat [Deployment environment produksi](../get-started/deployment/production.md)
+- Sub-app dalam deployment NocoBase yang sama dibedakan berdasarkan nama aplikasi dan tidak memerlukan hostname terpisah. Namun, layanan independen pada port lain tetap harus diisolasi dengan hostname jika memiliki aplikasi utama atau sub-app dengan nama yang sama

 Saat men-deploy NocoBase di lingkungan produksi, karena perbedaan cara build pada sistem dan lingkungan yang berbeda, instalasi dependencies bisa menjadi rumit. Untuk mendapatkan pengalaman fitur yang lengkap, kami merekomendasikan menggunakan **Docker** untuk deployment. Jika lingkungan sistem tidak dapat menggunakan Docker, Anda juga dapat menggunakan **create-nocobase-app** untuk deployment.
 
-:::warning
+:::warning Perhatian
 
 Tidak disarankan untuk langsung men-deploy source code di lingkungan produksi. Source code memiliki banyak dependencies, ukuran yang besar, dan kompilasi penuh memerlukan CPU dan memori yang tinggi. Jika benar-benar perlu menggunakan source code untuk deployment, disarankan untuk membangun image Docker kustom terlebih dahulu, kemudian melakukan deployment.
 
 :::
 
+:::warning Perhatian
+
+Jika men-deploy beberapa layanan NocoBase yang berdiri sendiri, gunakan `hostname` yang berbeda untuk setiap layanan, misalnya subdomain yang berbeda. Jangan hanya membedakan layanan berdasarkan port seperti `https://example.com:13000` dan `https://example.com:14000`.
+
+NocoBase menggunakan cookie untuk mempertahankan status login dan [izin akses file](../../file-manager/stable-url.md). Browser tidak mengisolasi cookie berdasarkan port, sehingga layanan pada port berbeda di bawah `hostname` yang sama dapat berbagi cookie dengan nama yang sama. Hal ini dapat menimpa status login atau menyebabkan kegagalan otorisasi pada pratinjau dan unduhan file.
+
+Sub-app dalam deployment NocoBase yang sama tidak termasuk dalam pembatasan ini. Cookie login dibedakan berdasarkan nama aplikasi, sehingga aplikasi utama dan sub-app dengan nama berbeda dapat berbagi `hostname` yang sama.
+
+Namun, layanan independen tetap harus diisolasi. Jika layanan NocoBase lain berjalan pada port berbeda di bawah `hostname` yang sama dan memiliki aplikasi utama atau sub-app dengan nama yang sama, cookie tetap dapat mengalami konflik.
+
+Gunakan alamat seperti `app1.example.com` dan `app2.example.com`, lalu arahkan ke layanan NocoBase yang berbeda melalui Nginx atau Caddy.
+
+:::
+
+## Frontend terpisah / Akses API lintas origin
+
+Sebaiknya halaman dan API tetap berada pada origin yang sama: gunakan reverse proxy di domain yang sama untuk meneruskan `${APP_PUBLIC_PATH}api/` dan `${APP_PUBLIC_PATH}files/` ke layanan NocoBase, lalu biarkan `API_BASE_URL` kosong.
+
+Jika halaman memang harus mengakses API secara lintas origin (`API_BASE_URL` menunjuk ke origin lain), tambahkan origin halaman ke `CORS_ORIGIN_WHITELIST`. Jika tidak, browser akan mengabaikan `Set-Cookie` pada respons API, cookie login tidak akan tersimpan, dan pratinjau maupun unduhan melalui stable file URL akan gagal otorisasi.
+
+Perhatikan juga bahwa cookie disimpan per `hostname`: jika halaman dan API menggunakan domain yang benar-benar berbeda, permintaan ke `/files/` dari domain halaman tidak akan membawa cookie login yang tersimpan di domain API. Deployment seperti ini sebaiknya diubah ke reverse proxy same-origin. Lihat [Variabel lingkungan](../installation/env.md#api_base_url).

+keywords: "安定 URL,プロキシ URL,永久 URL,ファイルアクセス,Office プレビュー,NocoBase"
+---
+
+# 安定 URL
+
+NocoBase のストレージエンジンで管理されるファイルは、**安定 URL** を通してアクセスされます。NocoBase がファイルレコードと権限を確認した後、ストレージエンジンが生成した実際の URL へリダイレクトします。
+
+## URL 形式
+
+```text
+/files/<app>/<dataSource>/<collection>/<id><extname>
+```
+
+`APP_PUBLIC_PATH=/nocobase` の場合は `/nocobase/files/` から始まります。ファイル作成後は ID と拡張子を変更できないため、レコードが存在する間は URL が安定します。
+
+| 用途 | URL | 動作 |
+|---|---|---|
+| 表示 | `/files/.../42.pdf` | 権限確認後に実ファイルへリダイレクト |
+| プレビュー | `/files/.../42.png?preview=1` | プレビューまたはサムネイルへリダイレクト |
+| ダウンロード | `/files/.../42.pdf?download=1` | ダウンロード用 URL へリダイレクト |
+| Office | `/files/.../42.xlsx?temporaryAccessToken=...` | Office Viewer が短時間だけ取得できる URL |
+
+## 各機能での動作
+
+- 添付フィールド、ファイルテーブル、[HTTP API](./http-api.md) は `url` と `preview` に安定 URL を返します
+- Markdown にアップロードしたファイルも安定 URL を保存し、非公開の S3、OSS、COS、S3 Pro を利用できます
+- 添付 URL フィールドでアップロードした管理対象ファイルは安定 URL を保存し、手入力した外部 URL はそのまま保持します
+- 通常の画像、PDF、音声、動画、テキストプレビューは現在の NocoBase ログイン状態とファイル閲覧権限を使用します
+- 公開フォームでは、同じ公開フォームセッションでアップロードしたファイルだけに限定アクセスできます
+
+## Office プレビュー
+
+Microsoft Office Online Viewer はユーザーの NocoBase cookie を利用できません。Office プレビューを開くと、NocoBase は先に閲覧権限を確認し、そのファイル専用の短期 URL を発行します。既定の有効期間は 10 分で、`TEMPORARY_FILE_ACCESS_EXPIRES_IN` により 5〜10 分に設定できます。
+
+一時 URL を添付フィールド、Markdown、業務データに保存したり、共有リンクとして使用したりしないでください。
+
+## 注意事項
+
+- 安定 URL は公開 URL ではなく、閲覧者にはログインまたは anonymous 権限が必要です
+- ファイルレコードを削除した場合や、アプリ、データソース、ファイルテーブルが変わった場合、元の URL は無効になります
+- 応答は `302` です。CLI クライアントはリダイレクトを追跡する必要があります
+- `302 Location` や `temporaryAccessToken` を永続化しないでください
+- リバースプロキシは `APP_PUBLIC_PATH` 配下の `/files/` を NocoBase に転送する必要があります。サブパスにデプロイする場合は、ルートの `/files/` 互換ルートも残してください。NocoBase CLI が生成する設定には両方のルールが自動的に含まれます
+- ページが API にクロスオリジンでアクセスする構成（`API_BASE_URL` が別オリジンを指す場合）では、ページのオリジンを `CORS_ORIGIN_WHITELIST` に追加する必要があります。そうしないとログイン cookie が保存されず、stable URL は認証情報不足で `403` を返します。詳しくは[環境変数](../get-started/installation/env.md#api_base_url)を参照してください
+- 独立した複数の NocoBase サービスをデプロイする場合は、ポートだけで区別せず、それぞれに異なる `hostname` を使用してください。ブラウザーの cookie はポートでは分離されません。詳細は[本番環境へのデプロイ](../get-started/deployment/production.md)を参照してください
+- 同じ NocoBase デプロイ環境内のサブアプリはアプリ名で区別されるため、個別の hostname は必要ありません。ただし、別ポート上の独立したサービスに同名のメインアプリまたはサブアプリがある場合は、引き続き異なる hostname で分離する必要があります

 本番環境でソースコードから直接デプロイすることは推奨されません。ソースコードは依存関係が多く、サイズが大きいため、フルコンパイルには高いCPUとメモリが要求されます。どうしてもソースコードからデプロイする必要がある場合は、まずカスタムDockerイメージをビルドしてからデプロイすることをお勧めします。

+
+あわせて、cookie は `hostname` ごとに保存される点にも注意してください。ページと API が完全に異なるドメインを使っている場合、ページ側ドメインから `/files/` へ送るリクエストには API ドメインに保存されたログイン cookie が含まれません。この種の構成は、同一オリジンのリバースプロキシへ切り替えるべきです。詳しくは[環境変数](../installation/env.md#api_base_url)を参照してください。

+
+# URL estável
+
+Arquivos gerenciados por um mecanismo de armazenamento são acessados por uma **URL estável**. O NocoBase verifica o registro e as permissões e depois redireciona para a URL real gerada pelo armazenamento.
+
+## Formato
+
+```text
+/files/<app>/<dataSource>/<collection>/<id><extname>
+```
+
+Com `APP_PUBLIC_PATH=/nocobase`, o caminho começa com `/nocobase/files/`. O ID e a extensão não podem ser alterados após a criação, mantendo a URL estável enquanto o registro existir.
+
+| Uso | URL | Comportamento |
+|---|---|---|
+| Abrir | `/files/.../42.pdf` | Verifica a permissão e redireciona para o arquivo |
+| Pré-visualizar | `/files/.../42.png?preview=1` | Redireciona para a miniatura ou pré-visualização |
+| Baixar | `/files/.../42.pdf?download=1` | Redireciona com semântica de download |
+| Office | `/files/.../42.xlsx?temporaryAccessToken=...` | Acesso temporário para o Office Online Viewer |
+
+## Comportamento no NocoBase
+
+- Campos de anexo, tabelas de arquivos e a [HTTP API](./http-api.md) retornam URLs estáveis em `url` e `preview`
+- O Markdown salva a URL estável e pode usar S3, OSS, COS ou S3 Pro privados
+- O campo URL de anexo preserva URLs externas inseridas manualmente e usa a URL estável para uploads gerenciados
+- As pré-visualizações comuns usam a sessão e as permissões atuais do NocoBase
+- Formulários públicos concedem acesso limitado apenas aos arquivos enviados na sessão atual do formulário
+
+## Pré-visualização do Office
+
+O Microsoft Office Online Viewer não pode usar o cookie do usuário. Ao abrir a pré-visualização, o NocoBase verifica a permissão e emite uma URL temporária vinculada ao arquivo. Ela dura 10 minutos por padrão e pode ser configurada entre 5 e 10 minutos com `TEMPORARY_FILE_ACCESS_EXPIRES_IN`.
+
+Não salve essa URL em campos, Markdown ou dados de negócio e não a use como link de compartilhamento.
+
+## Cuidados
+
+- Estável não significa público; o destinatário ainda precisa de permissão
+- Excluir ou mover o registro para outro contexto invalida a URL antiga
+- A resposta é um redirecionamento `302`, que o cliente deve seguir
+- Não persista `302 Location` nem `temporaryAccessToken`
+- O proxy reverso deve encaminhar ao NocoBase a rota `/files/` sob `APP_PUBLIC_PATH`. Em implantações em subcaminhos, mantenha também a rota compatível `/files/` na raiz. As configurações geradas pela CLI do NocoBase incluem ambas as regras automaticamente
+- Em implantações nas quais as páginas acessam a API entre origens (`API_BASE_URL` apontando para outra origem), adicione a origem da página a `CORS_ORIGIN_WHITELIST`. Caso contrário, o cookie de login nunca será armazenado e as URLs estáveis retornarão `403` por falta de credenciais. Consulte [Variáveis de ambiente](../get-started/installation/env.md#api_base_url)
+- Use um `hostname` diferente para cada serviço NocoBase independente, em vez de diferenciá-los apenas pela porta. Os cookies do navegador não são isolados por porta; consulte [Implantação em produção](../get-started/deployment/production.md)
+- Os subaplicativos da mesma implantação do NocoBase são diferenciados pelo nome do aplicativo e não precisam de hostnames separados. No entanto, um serviço independente em outra porta ainda precisa ser isolado por hostname se contiver um aplicativo principal ou subaplicativo com o mesmo nome

 Ao implantar o NocoBase em um ambiente de produção, a instalação de dependências pode ser um pouco trabalhosa devido às diferenças nos métodos de construção entre os diversos sistemas e ambientes. Para ter uma experiência funcional completa, recomendamos a implantação com **Docker**. Se o seu ambiente não puder usar o Docker, você também pode implantar usando o **create-nocobase-app**.
 
-:::warning
+:::warning Atenção
 
 Não é recomendado implantar diretamente do código-fonte em um ambiente de produção. O código-fonte possui muitas dependências, é grande em tamanho e uma compilação completa exige bastante CPU e memória. Se você realmente precisar implantar a partir do código-fonte, sugerimos que primeiro construa uma imagem Docker personalizada e só então faça a implantação.
 
 :::
 
+:::warning Atenção
+
+Ao implantar vários serviços NocoBase independentes, use um `hostname` diferente para cada serviço, como subdomínios distintos. Não diferencie os serviços apenas pela porta, como `https://example.com:13000` e `https://example.com:14000`.
+
+O NocoBase usa cookies para manter o estado de login e as [permissões de acesso a arquivos](../../file-manager/stable-url.md). Os navegadores não isolam cookies por porta, portanto serviços em portas diferentes sob o mesmo `hostname` podem compartilhar cookies com o mesmo nome. Isso pode sobrescrever o estado de login ou causar falhas de autorização na pré-visualização e no download de arquivos.
+
+Os subaplicativos na mesma implantação do NocoBase não estão sujeitos a essa restrição. Os cookies de login são diferenciados pelo nome do aplicativo, portanto o aplicativo principal e subaplicativos com nomes diferentes podem compartilhar o mesmo `hostname`.
+
+No entanto, serviços independentes ainda precisam ser isolados. Se outro serviço NocoBase for executado em outra porta sob o mesmo `hostname` e contiver um aplicativo principal ou subaplicativo com o mesmo nome, os cookies ainda poderão entrar em conflito.
+
+Use endereços como `app1.example.com` e `app2.example.com` e encaminhe-os para serviços NocoBase diferentes por meio do Nginx ou Caddy.
+
+:::
+
+## Frontend separado / Acesso a API entre origens
+
+Prefira manter as páginas e a API na mesma origem: use um proxy reverso no mesmo domínio para encaminhar `${APP_PUBLIC_PATH}api/` e `${APP_PUBLIC_PATH}files/` para o serviço NocoBase e deixe `API_BASE_URL` vazio.
+
+Se as páginas precisarem acessar a API entre origens (`API_BASE_URL` apontando para outra origem), adicione a origem da página a `CORS_ORIGIN_WHITELIST`. Caso contrário, o navegador ignorará `Set-Cookie` nas respostas da API, o cookie de login não será armazenado e a visualização e o download por URLs estáveis de arquivo falharão na autorização.
+
+Observe também que os cookies são armazenados por `hostname`: quando as páginas e a API usam domínios totalmente diferentes, as requisições para `/files/` a partir do domínio da página não enviarão o cookie de login armazenado no domínio da API. Implantações assim devem ser alteradas para um proxy reverso de mesma origem. Consulte [Variáveis de ambiente](../installation/env.md#api_base_url).

+
+# Стабильный URL
+
+Файлы, управляемые хранилищем NocoBase, доступны через **стабильный URL**. NocoBase проверяет запись файла и права доступа, а затем перенаправляет запрос на фактический URL, созданный хранилищем.
+
+## Формат
+
+```text
+/files/<app>/<dataSource>/<collection>/<id><extname>
+```
+
+При `APP_PUBLIC_PATH=/nocobase` путь начинается с `/nocobase/files/`. ID и расширение нельзя изменить после создания, поэтому URL остаётся стабильным, пока существует запись.
+
+| Назначение | URL | Поведение |
+|---|---|---|
+| Открытие | `/files/.../42.pdf` | Проверяет права и перенаправляет к файлу |
+| Предпросмотр | `/files/.../42.png?preview=1` | Перенаправляет к миниатюре или версии для просмотра |
+| Скачивание | `/files/.../42.pdf?download=1` | Перенаправляет с режимом скачивания |
+| Office | `/files/.../42.xlsx?temporaryAccessToken=...` | Временный доступ для Office Online Viewer |
+
+## Поведение в NocoBase
+
+- Поля вложений, таблицы файлов и [HTTP API](./http-api.md) возвращают стабильные значения `url` и `preview`
+- Markdown сохраняет стабильный URL и поддерживает закрытые S3, OSS, COS и S3 Pro
+- Поле URL вложения сохраняет введённые вручную внешние URL, а для управляемых файлов использует стабильный URL
+- Обычный предпросмотр использует текущую сессию и права NocoBase
+- Публичная форма даёт ограниченный доступ только к файлам, загруженным в текущей сессии формы
+
+## Предпросмотр Office
+
+Microsoft Office Online Viewer не может использовать cookie пользователя NocoBase. При открытии NocoBase сначала проверяет право просмотра, а затем выдаёт временный URL, привязанный к файлу. По умолчанию он действует 10 минут; параметр `TEMPORARY_FILE_ACCESS_EXPIRES_IN` допускает значение от 5 до 10 минут.
+
+Не сохраняйте временный URL в полях, Markdown или бизнес-данных и не используйте его как ссылку общего доступа.
+
+## Важные замечания
+
+- Стабильный не означает публичный; получателю всё равно нужны права
+- Удаление или перенос записи делает старый URL недействительным
+- Ответ представляет собой перенаправление `302`, которому должен следовать клиент
+- Не сохраняйте `302 Location` и `temporaryAccessToken`
+- Обратный прокси должен передавать маршрут `/files/` в пределах `APP_PUBLIC_PATH` в NocoBase. При развёртывании в подпути также сохраните совместимый корневой маршрут `/files/`. Конфигурации, созданные NocoBase CLI, автоматически включают оба правила
+- В развёртываниях, где страницы обращаются к API между разными origin (`API_BASE_URL` указывает на другой origin), origin страницы нужно добавить в `CORS_ORIGIN_WHITELIST`. Иначе cookie входа не будет сохранена, а stable URL вернёт `403` из-за отсутствия учётных данных. См. [Переменные окружения](../get-started/installation/env.md#api_base_url)
+- Используйте отдельный `hostname` для каждого независимого сервиса NocoBase, а не различайте сервисы только по порту. Cookies браузера не изолируются по портам; см. [Развёртывание в рабочей среде](../get-started/deployment/production.md)
+- Подприложения в одном развёртывании NocoBase различаются по имени приложения и не требуют отдельных hostnames. Однако независимый сервис на другом порту всё равно должен быть изолирован по hostname, если он содержит основное или дочернее приложение с тем же именем

 При развертывании NocoBase в производственной среде установка зависимостей может быть довольно сложной из-за различий в методах сборки для разных систем и окружений. Для получения полного функционала мы рекомендуем использовать **Docker** для развертывания. Если ваша системная среда не позволяет использовать Docker, вы также можете развернуть NocoBase с помощью **create-nocobase-app**.
 
-:::warning
+:::warning Внимание
 
 Не рекомендуется развертывать NocoBase напрямую из исходного кода в производственной среде. Исходный код имеет множество зависимостей, он объемен, а полная компиляция требует значительных ресурсов CPU и памяти. Если вам все же необходимо развернуть NocoBase из исходного кода, рекомендуется сначала собрать собственный образ Docker, а затем выполнить развертывание.
 
 :::
 
+:::warning Внимание
+
+Если вы развёртываете несколько независимых сервисов NocoBase, используйте отдельный `hostname` для каждого сервиса, например разные поддомены. Не различайте сервисы только по порту, как в `https://example.com:13000` и `https://example.com:14000`.
+
+NocoBase использует cookies для сохранения состояния входа и [прав доступа к файлам](../../file-manager/stable-url.md). Браузеры не изолируют cookies по портам, поэтому сервисы на разных портах под одним `hostname` могут использовать одноимённые cookies. Это может привести к перезаписи состояния входа или ошибкам авторизации при предварительном просмотре и скачивании файлов.
+
+Подприложения в одном развёртывании NocoBase не подпадают под это ограничение. Cookies входа различаются по имени приложения, поэтому основное приложение и подприложения с разными именами могут использовать один `hostname`.
+
+Однако независимые сервисы по-прежнему необходимо изолировать. Если другой сервис NocoBase работает на другом порту под тем же `hostname` и содержит основное или дочернее приложение с тем же именем, cookies всё равно могут конфликтовать.
+
+Используйте адреса наподобие `app1.example.com` и `app2.example.com`, а затем направляйте их к разным сервисам NocoBase через Nginx или Caddy.

+Рекомендуется держать страницы и API на одном origin: используйте обратный прокси под одним доменом, чтобы направлять `${APP_PUBLIC_PATH}api/` и `${APP_PUBLIC_PATH}files/` в сервис NocoBase, а `API_BASE_URL` оставьте пустым.
+
+Если страницы должны обращаться к API с другого origin (`API_BASE_URL` указывает на другой origin), добавьте origin страницы в `CORS_ORIGIN_WHITELIST`. Иначе браузер проигнорирует `Set-Cookie` в ответах API, cookie входа не будет сохранена, а предпросмотр и скачивание через stable file URL завершатся ошибкой авторизации.
+
+Также учитывайте, что cookies хранятся по `hostname`: если страницы и API используют полностью разные домены, запросы к `/files/` с домена страницы не будут отправлять cookie входа, сохранённую для домена API. Для таких развёртываний следует перейти на same-origin reverse proxy. См. [Переменные окружения](../installation/env.md#api_base_url).

+
+# URL ổn định
+
+File do storage engine của NocoBase quản lý được truy cập qua **URL ổn định**. NocoBase kiểm tra bản ghi file và quyền truy cập, sau đó chuyển hướng đến URL thực tế do storage engine tạo ra.
+
+## Định dạng
+
+```text
+/files/<app>/<dataSource>/<collection>/<id><extname>
+```
+
+Khi cấu hình `APP_PUBLIC_PATH=/nocobase`, đường dẫn bắt đầu bằng `/nocobase/files/`. ID và phần mở rộng không thể thay đổi sau khi tạo, vì vậy URL giữ ổn định trong vòng đời của bản ghi.
+
+| Mục đích | URL | Hành vi |
+|---|---|---|
+| Mở file | `/files/.../42.pdf` | Kiểm tra quyền rồi chuyển hướng đến file |
+| Xem trước | `/files/.../42.png?preview=1` | Chuyển hướng đến ảnh thu nhỏ hoặc URL xem trước |
+| Tải xuống | `/files/.../42.pdf?download=1` | Chuyển hướng với chế độ tải xuống |
+| Office | `/files/.../42.xlsx?temporaryAccessToken=...` | Cấp quyền tạm thời cho Office Online Viewer |
+
+## Biểu hiện trong NocoBase
+
+- Field đính kèm, file collection và [HTTP API](./http-api.md) trả về URL ổn định trong `url` và `preview`
+- Markdown lưu URL ổn định và hỗ trợ S3, OSS, COS hoặc S3 Pro riêng tư
+- Field URL đính kèm giữ nguyên URL ngoài được nhập thủ công và dùng URL ổn định cho file do NocoBase quản lý
+- Chế độ xem trước thông thường dùng phiên đăng nhập và quyền file hiện tại của NocoBase
+- Form công khai chỉ cấp quyền giới hạn cho file được tải lên trong phiên form hiện tại
+
+## Xem trước Office
+
+Microsoft Office Online Viewer không thể dùng cookie NocoBase của người dùng. Khi mở xem trước, NocoBase kiểm tra quyền trước rồi cấp một URL tạm thời gắn với file. Thời hạn mặc định là 10 phút và có thể cấu hình từ 5 đến 10 phút bằng `TEMPORARY_FILE_ACCESS_EXPIRES_IN`.
+
+Không lưu URL tạm thời vào field, Markdown hoặc dữ liệu nghiệp vụ, và không dùng nó làm liên kết chia sẻ.
+
+## Lưu ý
+
+- Ổn định không có nghĩa là công khai; người nhận vẫn cần quyền truy cập
+- Xóa hoặc chuyển bản ghi sang ngữ cảnh khác sẽ làm URL cũ mất hiệu lực
+- Phản hồi là chuyển hướng `302`; client phải theo chuyển hướng
+- Không lưu `302 Location` hoặc `temporaryAccessToken`
+- Reverse proxy phải chuyển tiếp route `/files/` dưới `APP_PUBLIC_PATH` đến NocoBase. Khi triển khai dưới subpath, hãy giữ thêm route tương thích `/files/` ở root. Cấu hình do NocoBase CLI tạo sẽ tự động bao gồm cả hai rule
+- Với các deployment mà trang truy cập API theo cơ chế cross-origin (`API_BASE_URL` trỏ sang origin khác), cần thêm origin của trang vào `CORS_ORIGIN_WHITELIST`. Nếu không, cookie đăng nhập sẽ không được lưu và stable URL sẽ trả về `403` do thiếu thông tin xác thực. Xem [Biến môi trường](../get-started/installation/env.md#api_base_url)
+- Dùng `hostname` khác nhau cho từng dịch vụ NocoBase độc lập thay vì chỉ phân biệt bằng port. Cookie của trình duyệt không được cô lập theo port; xem [Triển khai môi trường production](../get-started/deployment/production.md)
+- Các sub-app trong cùng một deployment NocoBase được phân biệt theo tên ứng dụng và không cần hostname riêng. Tuy nhiên, dịch vụ độc lập ở port khác vẫn phải được cô lập bằng hostname nếu chứa main app hoặc sub-app trùng tên

 Khi triển khai NocoBase ở môi trường sản xuất, do cách build khác nhau giữa các hệ thống và môi trường, việc cài đặt phụ thuộc có thể khá phức tạp. Để có được trải nghiệm tính năng đầy đủ, chúng tôi khuyến nghị sử dụng **Docker** để triển khai. Nếu môi trường hệ thống không thể dùng Docker, cũng có thể dùng **create-nocobase-app** để triển khai.
 
-:::warning
+:::warning Lưu ý
 
 Không khuyến nghị triển khai trực tiếp từ mã nguồn ở môi trường sản xuất. Mã nguồn có nhiều phụ thuộc, dung lượng lớn và việc biên dịch toàn bộ yêu cầu cao về CPU và bộ nhớ. Nếu thật sự cần triển khai từ mã nguồn, khuyến nghị build image Docker tùy chỉnh trước, sau đó mới triển khai.
 
 :::
 
+:::warning Lưu ý
+
+Nếu triển khai nhiều dịch vụ NocoBase độc lập, hãy dùng `hostname` khác nhau cho từng dịch vụ, chẳng hạn các subdomain riêng. Không chỉ phân biệt dịch vụ bằng port như `https://example.com:13000` và `https://example.com:14000`.
+
+NocoBase dùng cookie để duy trì trạng thái đăng nhập và [quyền truy cập file](../../file-manager/stable-url.md). Trình duyệt không cô lập cookie theo port, vì vậy các dịch vụ ở những port khác nhau dưới cùng một `hostname` có thể dùng chung cookie trùng tên. Điều này có thể ghi đè trạng thái đăng nhập hoặc gây lỗi xác thực khi xem trước và tải file.
+
+Các sub-app trong cùng một deployment NocoBase không thuộc phạm vi hạn chế này. Cookie đăng nhập được phân biệt theo tên ứng dụng, nên main app và các sub-app khác tên có thể dùng chung một `hostname`.
+
+Tuy nhiên, các dịch vụ độc lập vẫn phải được cô lập. Nếu một dịch vụ NocoBase khác chạy trên port khác dưới cùng `hostname` và chứa main app hoặc sub-app trùng tên, cookie vẫn có thể xung đột.
+
+Hãy dùng các địa chỉ như `app1.example.com` và `app2.example.com`, sau đó định tuyến chúng đến các dịch vụ NocoBase khác nhau qua Nginx hoặc Caddy.
+
+:::
+
+## Frontend tách rời / Truy cập API cross-origin
+
+Nên giữ trang và API cùng origin: dùng reverse proxy dưới cùng một domain để chuyển tiếp `${APP_PUBLIC_PATH}api/` và `${APP_PUBLIC_PATH}files/` đến dịch vụ NocoBase, đồng thời để trống `API_BASE_URL`.
+
+Nếu trang buộc phải truy cập API theo cơ chế cross-origin (`API_BASE_URL` trỏ sang origin khác), hãy thêm origin của trang vào `CORS_ORIGIN_WHITELIST`. Nếu không, trình duyệt sẽ bỏ qua `Set-Cookie` trong phản hồi API, cookie đăng nhập sẽ không được lưu, và việc xem trước hay tải xuống qua stable file URL sẽ thất bại ở bước xác thực.
+
+Đồng thời lưu ý rằng cookie được lưu theo `hostname`: nếu trang và API dùng hai domain hoàn toàn khác nhau, các request tới `/files/` từ domain của trang sẽ không mang theo cookie đăng nhập được lưu dưới domain của API. Với kiểu triển khai này, nên chuyển sang reverse proxy cùng origin. Xem [Biến môi trường](../installation/env.md#api_base_url).
+
 ## Quy trình triển khai
 
 Triển khai môi trường sản xuất có thể tham khảo các bước cài đặt và nâng cấp đã có.
