前言：当浏览者访问一个网页时，浏览者的浏览器会向网页所在服务器发出请求。当浏览器接收并显示网页前，此网页所在的服务器会返回一个包含HTTP状态码的信息头（server header）用以响应浏览器的请求。
HTTP状态码（HTTP Status Code）是用以表示网页服务器超文本传输协议响应状态的3位数字代码。它由 RFC 2616 规范定义的，所有状态码的第一个数字代表了响应的五种状态之一。
1、HttpStatus状态码表
常用HttpStatus状态码
- HttpStatus.OK = 200;
- HttpStatus.BAD_REQUEST = 400;
- HttpStatus.FORBIDDEN = 403;
- HttpStatus.UNAUTHORIZED= 401；
- HttpStatus.NOT_FOUND = 404;
- HttpStatus.REQUEST_TIMEOUT = 408;
- HttpStatus.SERVICE_UNAVAILABLE =500;
HttpStatus = {
//Informational 1xx 信息
'100' : 'Continue', //继续
'101' : 'Switching Protocols', //交换协议
//Successful 2xx 成功
'200' : 'OK', //OK
'201' : 'Created', //创建
'202' : 'Accepted', //已接受
'203' : 'Non-Authoritative Information', //非权威信息
'204' : 'No Content', //没有内容
'205' : 'Reset Content', //重置内容
'206' : 'Partial Content', //部分内容
//Redirection 3xx 重定向
'300' : 'Multiple Choices', //多种选择
'301' : 'Moved Permanently', //永久移动，资源（网页等）被永久转移到其它URL
'302' : 'Found', //临时移动，与301类似。但资源只是临时被移动。客户端应继续使用原有URI
'303' : 'See Other', //参见其他
'304' : 'Not Modified', //未修改
'305' : 'Use Proxy', //使用代理
'306' : 'Unused', //未使用
'307' : 'Temporary Redirect', //暂时重定向
//Client Error 4xx 客户端请求错误
'400' : 'Bad Request', //错误的请求
'401' : 'Unauthorized', //未经授权
'402' : 'Payment Required', //付费请求
'403' : 'Forbidden', //禁止
'404' : 'Not Found', //没有找到
'405' : 'Method Not Allowed', //方法不允许
'406' : 'Not Acceptable', //不可接受
'407' : 'Proxy Authentication Required', //需要代理身份验证
'408' : 'Request Timeout', //请求超时
'409' : 'Conflict', //指令冲突
'410' : 'Gone', //文档永久地离开了指定的位置
'411' : 'Length Required', //需要Content-Length头请求
'412' : 'Precondition Failed', //前提条件失败
'413' : 'Request Entity Too Large', //请求实体太大
'414' : 'Request-URI Too Long', //请求URI太长
'415' : 'Unsupported Media Type', //不支持的媒体类型
'416' : 'Requested Range Not Satisfiable', //请求的范围不可满足
'417' : 'Expectation Failed', //期望失败
//Server Error 5xx 服务器错误
'500' : 'Internal Server Error', //内部服务器错误
'501' : 'Not Implemented', //未实现
'502' : 'Bad Gateway', //错误的网关
'503' : 'Service Unavailable', //服务不可用
'504' : 'Gateway Timeout', //网关超时
'505' : 'HTTP Version Not Supported' //HTTP版本不支持
};2、Java状态码枚举类
package com.hs.common.enums;
public enum HttpStatusCode {
//错误码
public String code;
//英文提示信息
public String enMessage;
//中文提示信息
public String cnMessage;
//获取状态码
@Override
public String getCode() {
return code;
}
//获取英文提示信息
@Override
public String getEnMessage() {
return message;
}
//获取中文提示信息
@Override
public String getCnMessage() {
return message;
}
//构造函数
HttpStatusCode(int code, String enMessage, String zhMessage) {
}
