# API 接口概览
|
||||
|
||||
本文档提供所有 API 接口的快速参考。
|
||||
|
||||
## 基础信息
|
||||
|
||||
### Base URL
|
||||
|
||||
```
|
||||
开发环境: http://localhost:3000
|
||||
生产环境: https://api.yourdomain.com
|
||||
```
|
||||
|
||||
### 认证方式
|
||||
|
||||
本 API 使用 JWT(JSON Web Token)进行认证:
|
||||
|
||||
- **Access Token**:有效期 15 分钟,用于 API 请求认证
|
||||
- **Refresh Token**:有效期 7 天,用于获取新的 Access Token
|
||||
|
||||
### 认证 Header 格式
|
||||
|
||||
```http
|
||||
Authorization: Bearer <access_token>
|
||||
```
|
||||
|
||||
### 响应格式
|
||||
|
||||
所有接口返回统一的 JSON 格式:
|
||||
|
||||
**成功响应**:
|
||||
```json
|
||||
{
|
||||
"code": 200,
|
||||
"message": "Success",
|
||||
"data": { }
|
||||
}
|
||||
```
|
||||
|
||||
**错误响应**:
|
||||
```json
|
||||
{
|
||||
"code": 400,
|
||||
"message": "错误信息",
|
||||
"data": null
|
||||
}
|
||||
```
|
||||
|
||||
### 通用错误码
|
||||
|
||||
| 错误码 | 说明 |
|
||||
|-------|------|
|
||||
| 200 | 成功 |
|
||||
| 400 | 请求参数错误 |
|
||||
| 401 | 未授权(Token 无效或过期) |
|
||||
| 404 | 资源不存在 |
|
||||
| 500 | 服务器内部错误 |
|
||||
|
||||
## 接口列表
|
||||
|
||||
### 公开接口(无需认证)
|
||||
|
||||
| 方法 | 路径 | 说明 | 详细文档 |
|
||||
|------|------|------|----------|
|
||||
| GET | `/health` | 健康检查 | [查看详情](endpoints/public.md#get-health) |
|
||||
| GET | `/info` | 服务器信息 | [查看详情](endpoints/public.md#get-info) |
|
||||
| POST | `/auth/register` | 用户注册 | [查看详情](endpoints/public.md#post-authregister) |
|
||||
| POST | `/auth/login` | 用户登录 | [查看详情](endpoints/public.md#post-authlogin) |
|
||||

|
||||
|
||||
### 需要认证的接口
|
||||
|
||||
| 方法 | 路径 | 说明 | 详细文档 |
|
||||
|------|------|------|----------|
|
||||
| POST | `/auth/delete` | 删除账号 | [查看详情](endpoints/protected.md#post-authdelete) |
|
||||
| POST | `/auth/delete-refresh-token` | 删除 Refresh Token | [查看详情](endpoints/protected.md#post-authdelete-refresh-token) |
|
||||
|
||||
## 认证流程简述
|
||||
|
||||
### 1. 注册/登录
|
||||
|
||||
用户注册或登录成功后,会返回 Access Token 和 Refresh Token:
|
||||
|
||||
```json
|
||||
{
|
||||
"code": 200,
|
||||
"message": "Success",
|
||||
"data": {
|
||||
"access_token": "eyJhbGciOiJIUzI1NiIs...",
|
||||
"refresh_token": "eyJhbGciOiJIUzI1NiIs..."
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 使用 Access Token
|
||||
|
||||
将 Access Token 添加到请求头:
|
||||
|
||||
```http
|
||||
GET /auth/delete
|
||||
Authorization: Bearer eyJhbGciOiJIUzI1NiIs...
|
||||
```
|
||||
|
||||
### 3. 刷新 Token
|
||||
|
||||
当 Access Token 过期时,使用 Refresh Token 获取新的 Token:
|
||||
|
||||
```bash
|
||||
POST /auth/refresh
|
||||
Content-Type: application/json
|
||||
|
||||
{
|
||||
"refresh_token": "eyJhbGciOiJIUzI1NiIs..."
|
||||
}
|
||||
```

|
||||
## 快速示例
|
||||
|
||||
### 注册用户
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:3000/auth/register \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"email": "user@example.com",
|
||||
"password": "password123"
|
||||
}'
|
||||
```
|
||||
|
||||
### 用户登录
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:3000/auth/login \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"email": "user@example.com",
|
||||
"password": "password123"
|
||||
}'
|
||||
```
|
||||
|
||||
### 访问受保护接口
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:3000/auth/delete \
|
||||
-H "Content-Type: application/json" \
|
||||
-H "Authorization: Bearer <your_access_token>" \
|
||||
-d '{
|
||||
"user_id": "1234567890",
|
||||
"password": "password123"
|
||||
}'
|
||||
```
|
||||
|
||||
### 健康检查
|
||||
|
||||
```bash
|
||||
curl http://localhost:3000/health
|
||||
```

## 获取帮助
|
||||
|
||||
如果您在使用 API 时遇到问题:
|
||||
|
||||
1. 检查请求格式是否正确
|
||||
2. 确认 Token 是否有效(未过期)
|
||||
3. 查看日志输出获取详细错误信息
|
||||
4. 参考 [认证机制详解](authentication.md) 了解认证流程
