- 防止SQL注入和XSS攻击

## 8. 集成指南

### 8.1 前端集成

前端应用可以通过以下步骤集成订单管理API：

1. 获取认证Token
2. 设置Trace Context头
3. 调用相应的API端点
4. 处理响应和错误

### 8.2 第三方平台集成

第三方平台可以通过Webhook方式与订单系统集成：

1. 在平台设置Webhook URL: `https://your-domain.com/api/v1/orders/webhook/:platform`
2. 确保包含必要的认证信息
3. 按照平台的格式发送订单数据

## 9. 监控与日志

- 所有API调用都有详细的日志记录
- 关键操作有审计追踪
- 性能指标实时监控
- 异常情况自动告警

## 10. 版本控制

- **v1**: 当前版本
- 后续版本将通过URL路径进行区分
