DC3 API Auth

Overview

dc3-api-auth provides gRPC service definitions for authentication and authorization in the IoT DC3 platform. It defines the interfaces for tenant management, user authentication, token validation, and user login operations.

Module Information

• Group ID: io.github.pnoker
• Artifact ID: dc3-api-auth
• Version: 2026.5.17
• Package: io.github.pnoker.api.center.auth

Proto Definitions

tenant.proto

Defines tenant-related RPC calls and data structures.

Service: TenantApi

• SelectByCode - Query tenant information by tenant code

Key Messages:

• GrpcCodeQuery - Request wrapper for tenant code queries
• GrpcRTenantDTO - Response wrapper containing tenant information
• GrpcTenantDTO - Tenant data structure (name, code, enable flag)

token.proto

Defines token validation RPC calls and data structures.

Service: TokenApi

• CheckValid - Validate authentication tokens

Key Messages:

• GrpcLoginQuery - Request wrapper with login credentials (tenant, name, password, token)
• GrpcRTokenDTO - Response wrapper with validation result

user.proto

Defines user-related RPC calls and data structures.

Service: UserApi

• SelectById - Query user information by user ID

Key Messages:

• GrpcIdQuery - Request wrapper for user ID queries
• GrpcRUserDTO - Response wrapper containing user information
• GrpcUserDTO - User data structure (nickname, username, phone, email)

user_login.proto

Defines user login-related RPC calls and data structures.

Service: UserLoginApi

• SelectByName - Query user login information by login name

Key Messages:

• GrpcNameQuery - Request wrapper for name-based queries
• GrpcRUserLoginDTO - Response wrapper containing login information
• GrpcUserLoginDTO - User login data structure (login name, user ID, password ID)

Dependencies

This module depends on common proto definitions:

• api/common/base.proto - Base entity fields (ID, timestamps)
• api/common/r.proto - Common response wrapper

Usage

1. Add Dependency

<dependency>
    <groupId>io.github.pnoker</groupId>
    <artifactId>dc3-api-auth</artifactId>
    <version>2026.5.17</version>
</dependency>

2. Import Proto Files

import "api/common/auth/tenant.proto";
import "api/common/auth/token.proto";
import "api/common/auth/user.proto";
import "api/common/auth/user_login.proto";

3. Implement Service

public class TenantServiceImpl extends TenantApiGrpc.TenantApiImplBase {
    @Override
    public void selectByCode(GrpcCodeQuery request,
                             StreamObserver<GrpcRTenantDTO> responseObserver) {
        // Implementation
    }
}

API Features

Multi-Tenancy Support

• Tenant isolation through tenant codes
• Tenant-scoped user management
• Cross-tenant operations support

Authentication Flow

1. Client queries tenant by code
2. User login validation via UserLoginApi
3. Token validation via TokenApi
4. User information retrieval via UserApi

Security Features

• Encrypted password storage (salt-based)
• Token-based authentication
• User credential management
• Login tracking with password IDs

Data Models

Tenant Model

• tenant_name: Display name of the tenant
• tenant_code: Unique tenant identifier
• enable_flag: Active/inactive status (1=enabled, 0=disabled)

User Model

• nick_name: Display name
• user_name: Unique username
• phone: Contact phone number
• email: Email address
• social_ext: Encrypted social account information
• identity_ext: Encrypted identity verification data

User Login Model

• login_name: Username for authentication
• user_id: Reference to user entity
• user_password_id: Reference to password record
• enable_flag: Account status
