golang 设置web请求状态码操作
我就废话不多说了，大家还是直接看代码吧~
packagemain
import(
"net/http"
)
funcmain(){
//路由处理绑定
http.HandleFunc("/",Hander)
//监听8080端口
http.ListenAndServe(":8080",nil)
}
funcHander(whttp.ResponseWriter,req*http.Request){
//设置http请求状态
w.WriteHeader(500)
//写入页面数据
w.Write([]byte("xiaochuan"))
}
你也可以用http包里面的常量我这边直接写数字方便理解而已
const( StatusContinue=100 StatusSwitchingProtocols=101 StatusOK=200 StatusCreated=201 StatusAccepted=202 StatusNonAuthoritativeInfo=203 StatusNoContent=204 StatusResetContent=205 StatusPartialContent=206 StatusMultipleChoices=300 StatusMovedPermanently=301 StatusFound=302 StatusSeeOther=303 StatusNotModified=304 StatusUseProxy=305 StatusTemporaryRedirect=307 StatusBadRequest=400 StatusUnauthorized=401 StatusPaymentRequired=402 StatusForbidden=403 StatusNotFound=404 StatusMethodNotAllowed=405 StatusNotAcceptable=406 StatusProxyAuthRequired=407 StatusRequestTimeout=408 StatusConflict=409 StatusGone=410 StatusLengthRequired=411 StatusPreconditionFailed=412 StatusRequestEntityTooLarge=413 StatusRequestURITooLong=414 StatusUnsupportedMediaType=415 StatusRequestedRangeNotSatisfiable=416 StatusExpectationFailed=417 StatusTeapot=418 StatusInternalServerError=500 StatusNotImplemented=501 StatusBadGateway=502 StatusServiceUnavailable=503 StatusGatewayTimeout=504 StatusHTTPVersionNotSupported=505 //NewHTTPstatuscodesfromRFC6585.NotexportedyetinGo1.1. //Seediscussionathttps://codereview.appspot.com/7678043/ statusPreconditionRequired=428 statusTooManyRequests=429 statusRequestHeaderFieldsTooLarge=431 statusNetworkAuthenticationRequired=511 )
下面修改一下就是这个样子
packagemain
import(
"net/http"
)
funcmain(){
//路由处理绑定
http.HandleFunc("/",Hander)
//监听8080端口
http.ListenAndServe(":8080",nil)
}
funcHander(whttp.ResponseWriter,req*http.Request){
//设置http请求状态为500
w.WriteHeader(http.StatusInternalServerError)
//写入页面数据
w.Write([]byte("xiaochuan"))
}
补充：gostatus.go状态码定义
status.go使用了一个map集合定义了http的响应状态码

以上为个人经验，希望能给大家一个参考，也希望大家多多支持毛票票。如有错误或未考虑完全的地方，望不吝赐教。
