状态 Code 分类
HTTP 状态 codes are divided into 5 major 分类, with the first digit indicating the 分类: 1xx (信息性), 2xx (成功), 3xx (重定向), 4xx (客户端错误), 5xx (服务器错误). Each 状态 code has specific meaning and purpose.
最佳实践
Always return appropriate 状态 codes in API responses. Use 2xx for 成功, 4xx for client errors, and 5xx for server errors. Include helpful error messages in response body for 4xx and 5xx codes.
Debugging 提示
Use browser DevTools Network tab to inspect 状态 codes and response headers. Check server logs for 5xx errors. Verify API documentation for correct 状态 code usage. Test error scenarios in development environment before production.
