+# API 测试指南
+
+## 测试后端 API
+
+### 1. 获取 Token (登录)
+
+```bash
+curl -X POST http://localhost:8000/api/auth/login/ \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "your@email.com",
+    "password": "your_password"
+  }'
+```
+
+响应示例：
+```json
+{
+  "access": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
+  "refresh": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
+  "user": {
+    "id": 1,
+    "email": "your@email.com",
+    "username": "your_username",
+    "first_name": "First",
+    "last_name": "Last"
+  }
+}
+```
+
+### 2. 刷新 Token
+
+```bash
+curl -X POST http://localhost:8000/api/auth/token/refresh/ \
+  -H "Content-Type: application/json" \
+  -d '{
+    "refresh": "your_refresh_token"
+  }'
+```
+
+### 3. 获取用户列表 (需要认证)
+
+```bash
+curl -X GET http://localhost:8000/api/users/ \
+  -H "Authorization: Bearer your_access_token"
+```
+
+### 4. 获取当前用户
+
+```bash
+curl -X GET http://localhost:8000/api/users/me/ \
+  -H "Authorization: Bearer your_access_token"
+```
+
+## GraphQL 测试
+
+访问 http://localhost:8000/graphql/?graphiql
+
+### 查询所有用户
+
+```graphql
+query {
+  allUsers {
+    id
+    email
+    username
+    firstName
+    lastName
+  }
+}
+```
+
+### 查询当前用户
+
+```graphql
+query {
+  me {
+    id
+    email
+    username
+    firstName
+    lastName
+  }
+}
+```
+
+## Postman 集合
+
+你可以导入以下 Postman 集合来测试 API：
+
+### 环境变量
+- `base_url`: http://localhost:8000
+- `access_token`: (登录后自动填充)
+
+### 请求示例
+
+**1. 登录**
+- Method: POST
+- URL: `{{base_url}}/api/auth/login/`
+- Body:
+```json
+{
+  "email": "test@example.com",
+  "password": "testpass123"
+}
+```
+- Tests (自动提取 token):
+```javascript
+var jsonData = pm.response.json();
+pm.environment.set("access_token", jsonData.access);
+```
+
+**2. 获取用户**
+- Method: GET
+- URL: `{{base_url}}/api/users/`
+- Headers:
+```
+Authorization: Bearer {{access_token}}
+```
+
+**3. 获取当前用户**
+- Method: GET
+- URL: `{{base_url}}/api/users/me/`
+- Headers:
+```
+Authorization: Bearer {{access_token}}
+```
+
+## 自动化测试
+
+### 后端测试
+
+```bash
+cd backend
+python manage.py test
+```
+
+### 前端测试
+
+```bash
+cd frontend
+npm test
+```
+
+## 常见错误
+
+### 401 Unauthorized
+- Token 过期，使用 refresh_token 刷新
+- Token 格式错误，确保 `Bearer` 前缀存在
+- Token 被吊销
+
+### 403 Forbidden
+- 权限不足，检查用户是否有相应权限
+- CSRF token 问题（开发环境可能遇到）
+
+### 404 Not Found
+- 端点不存在，检查 URL 路径
+- 检查 Django 是否正确启动
+
+### 500 Server Error
+- 检查 Django 日志
+- 检查数据库连接
+- 检查代码语法错误
