# Pixel Game Server API 文档

**版本**: 1.1.1  
**更新时间**: 2025-12-25

## 🚨 后端对前端的提示与注意点

### 重要提醒
1. **邮箱冲突检测**: 发送邮箱验证码前会检查邮箱是否已被注册，已注册邮箱返回409状态码
2. **HTTP状态码**: 所有接口根据业务结果返回正确状态码（409冲突、400参数错误、401认证失败等）
3. **验证码有效期**: 所有验证码有效期为5分钟
4. **频率限制**: 验证码发送限制1次/分钟，注册限制10次/5分钟
5. **测试模式**: 开发环境下邮件服务返回206状态码，验证码在响应中返回
6. **冷却时间自动清除**: 注册、密码重置、验证码登录成功后会自动清除验证码冷却时间，方便后续操作
7. **邮件模板修复**: 登录验证码现在使用正确的邮件模板，内容为"登录验证码"而非"密码重置"

### 错误处理规范
- **409 Conflict**: 资源冲突（用户名、邮箱已存在）
- **400 Bad Request**: 参数错误、验证码错误
- **401 Unauthorized**: 认证失败、密码错误
- **429 Too Many Requests**: 频率限制
- **206 Partial Content**: 测试模式（验证码未真实发送）

### 前端开发建议
1. 根据HTTP状态码进行错误处理，不要只依赖success字段
2. 邮箱注册流程：先发送验证码 → 检查409冲突 → 使用验证码注册
3. 测试模式下验证码在响应中返回，生产环境需用户查收邮件
4. 实现重试机制处理429频率限制错误
5. 注册/重置密码成功后，验证码冷却时间会自动清除，可立即发送新验证码
