5xx（服务器错误）
这些状态代码表示，服务器在尝试处理请求时发生内部错误。这些错误可能是服务器本身的错误，而不是请求出错。
代码 说明
500（服务器内部错误） 服务器遇到错误，无法完成请求。
501（尚未实施） 服务器不具备完成请求的功能。例如，当服务器无法识别请求方法时，服务器可能会返回此代码。
502（错误网关） 服务器作为网关或代理，从上游服务器收到了无效的响应。
503（服务不可用） 目前无法使用服务器（由于超载或进行停机维护）。通常，这只是一种暂时的状态。
504（网关超时） 服务器作为网关或代理，未及时从上游服务器接收请求。
505（HTTP 版本不受支持） 服务器不支持请求中所使用的 HTTP 协议版本。
