# 🔌 客户端接入
|
||
|
||
本文档说明如何将下游客户端连接到 Metapi 代理网关。
|
||
|
||
[返回文档中心](./README.md)
|
||
|
||
---
|
||
|
||
## 通用配置
|
||
|
||
Metapi 暴露标准 OpenAI / Claude 兼容接口,下游客户端只需配置两项:
|
||
|
||
| 配置项 | 值 |
|
||
|--------|-----|
|
||
| **Base URL** | `https://your-domain.com`(不要拼接 `/v1`,客户端会自动加) |
|
||
| **API Key** | 你设置的 `PROXY_TOKEN` 值,或创建的下游 API Key |
|
||
|
||
模型列表自动从 `GET /v1/models` 获取,无需手动配置。
|
||
|
||
## 支持的接口
|
||
|
||
| 接口 | 方法 | 说明 |
|
||
|------|------|------|
|
||
| `/v1/responses` | POST | OpenAI Responses |
|
||
| `/v1/chat/completions` | POST | OpenAI Chat Completions |
|
||
| `/v1/messages` | POST | Claude Messages |
|
||
| `/v1/completions` | POST | OpenAI Completions(Legacy) |
|
||
| `/v1/embeddings` | POST | 向量嵌入 |
|
||
| `/v1/images/generations` | POST | 图像生成 |
|
||
| `/v1/models` | GET | 模型列表 |
|
||
|
||
## 已验证兼容的客户端
|
||
|
||
### ChatGPT-Next-Web
|
||
|
||
| 配置项 | 值 |
|
||
|--------|-----|
|
||
| Settings → Custom Endpoint | `https://your-domain.com` |
|
||
| API Key | `PROXY_TOKEN` |
|
||
|
||
### Open WebUI
|
||
|
||
| 配置项 | 值 |
|
||
|--------|-----|
|
||
| Settings → Connections → OpenAI API URL | `https://your-domain.com/v1` |
|
||
| API Key | `PROXY_TOKEN` |
|
||
|
||
### Cherry Studio
|
||
|
||
| 配置项 | 值 |
|
||
|--------|-----|
|
||
| 模型提供商 → OpenAI → API 地址 | `https://your-domain.com` |
|
||
| API Key | `PROXY_TOKEN` |
|
||
|
||
### Cursor
|
||
|
||
| 配置项 | 值 |
|
||
|--------|-----|
|
||
| Settings → Models → OpenAI API Key | `PROXY_TOKEN` |
|
||
| Override OpenAI Base URL | `https://your-domain.com/v1` |
|
||
|
||
### Claude Code
|
||
|
||
在 `~/.claude/settings.json` 中配置:
|
||
|
||
```json
|
||
{
|
||
“env”: {
|
||
“ANTHROPIC_BASE_URL”: “https://your-domain.com”,
|
||
“ANTHROPIC_API_KEY”: “your-proxy-sk-token”,
|
||
“ANTHROPIC_AUTH_TOKEN”: “your-proxy-sk-token”,
|
||
“CLAUDE_CODE_ATTRIBUTION_HEADER”: “0”,
|
||
“CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC”: “1”
|
||
}
|
||
}
|
||
```
|
||
|
||
> 说明:不同版本客户端可能读取 `ANTHROPIC_API_KEY` 或 `ANTHROPIC_AUTH_TOKEN`,建议同时设置。
|
||
> 上述变量由 Claude Code 客户端读取,属于客户端行为开关;
|
||
> `metapi` 服务端无法替代客户端”设置这些变量”,只能处理已经发来的请求。
|
||
|
||
### Codex CLI
|
||
|
||
`~/.codex/config.toml`
|
||
|
||
```toml
|
||
model = “gpt-5”
|
||
model_provider = “metapi”
|
||
|
||
[model_providers.metapi]
|
||
name = “metapi”
|
||
base_url = “https://your-domain.com/v1”
|
||
```
|
||
|
||
`~/.codex/auth.json`
|
||
|
||
```json
|
||
{
|
||
“OPENAI_API_KEY”: “your-proxy-sk-token”
|
||
}
|
||
```
|
||
|
||
> 提示:`model` 需要是你在 Metapi `GET /v1/models` 可见的模型名。
|
||
|
||
### Roo Code / Kilo Code
|
||
|
||
配置方式与 Cursor 类似,在设置中填入 Base URL 和 API Key。
|
||
|
||
### 其他客户端
|
||
|
||
所有支持 OpenAI API 格式的客户端均可接入,只需找到 Base URL 和 API Key 的配置位置即可。
|
||
|
||
## 下游 API Key 策略
|
||
|
||
除了全局 `PROXY_TOKEN`,你还可以在 **系统设置 → 下游 API Key 策略** 中创建多个项目级下游 Key,每个 Key 可独立配置:
|
||
|
||
| 配置项 | 说明 |
|
||
|--------|------|
|
||
| **过期时间**(ExpiresAt) | Key 到期后自动失效 |
|
||
| **费用上限**(MaxCost) | 累计消费超限后拒绝请求 |
|
||
| **请求上限**(MaxRequests) | 累计请求数超限后拒绝请求 |
|
||
| **模型白名单**(SupportedModels) | 限制可用模型,支持 exact / glob / `re:regex` |
|
||
| **路由白名单**(AllowedRouteIds) | 限制可走的路由规则 |
|
||
| **站点倍率**(SiteWeightMultipliers) | 按站点调整路由权重,控制上游偏好 |
|
||
|
||
适用于多团队/多项目共用一个 Metapi 实例但需要独立计量和权限控制的场景。

||
## 快速自检
|
||
|
||
部署完成后,用以下命令验证链路:
|
||
|
||
```bash
|
||
# 1. 检查模型列表
|
||
curl -sS https://your-domain.com/v1/models \
|
||
-H "Authorization: Bearer <PROXY_TOKEN>" | head -50
|
||
|
||
# 2. 测试对话(非流式)
|
||
curl -sS https://your-domain.com/v1/chat/completions \
|
||
-H "Authorization: Bearer <PROXY_TOKEN>" \
|
||
-H "Content-Type: application/json" \
|
||
-d '{"model":"gpt-4o-mini","messages":[{"role":"user","content":"hi"}]}'
|
||
|
||
# 3. 测试流式
|
||
curl -sS https://your-domain.com/v1/chat/completions \
|
||
-H "Authorization: Bearer <PROXY_TOKEN>" \
|
||
-H "Content-Type: application/json" \
|
||
-d '{"model":"gpt-4o-mini","messages":[{"role":"user","content":"hi"}],"stream":true}'
|
||
```
|
||
|
||
## 常见问题
|
||
|
||
### 流式响应异常
|
||
|
||
如果非流式正常但流式异常,原因几乎都是反向代理配置问题:
|
||
|
||
1. Nginx 未设置 `proxy_buffering off`
|
||
2. CDN 或中间层缓存了 SSE 响应
|
||
3. 中间层改写了 `text/event-stream` Content-Type
|
||
|
||
参考 [部署指南 → Nginx 配置](./deployment.md#nginx) 解决。
|
||
|
||
### 模型列表为空
|
||
|
||
- 检查是否已添加站点和账号
|
||
- 检查账号是否处于 `healthy` 状态
|
||
- 检查是否已同步 Token
|
||
- 在管理后台手动触发「刷新模型」
|
||
|
||
### 客户端提示 401 / 403
|
||
|
||
- 确认使用的是 `PROXY_TOKEN` 而非 `AUTH_TOKEN`
|
||
- 确认反向代理透传了 `Authorization` 请求头
