golang 设置web请求状态码操作
一名路过的小码农 人气:2这篇文章主要介绍了golang 设置web请求状态码操作，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧
我就废话不多说了，大家还是直接看代码吧~
package main
import (
"net/http"
)
func main() {
//路由处理绑定
http.HandleFunc("/", Hander)
//监听8080端口
http.ListenAndServe(":8080", nil)
}
func Hander(w http.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 // New HTTP status codes from RFC 6585. Not exported yet in Go 1.1. // See discussion at https://codereview.appspot.com/7678043/ statusPreconditionRequired = 428 statusTooManyRequests = 429 statusRequestHeaderFieldsTooLarge = 431 statusNetworkAuthenticationRequired = 511 )
下面修改一下就是这个样子
package main
import (
"net/http"
)
func main() {
//路由处理绑定
http.HandleFunc("/", Hander)
//监听8080端口
http.ListenAndServe(":8080", nil)
}
func Hander(w http.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：go status.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

// HTTP status codes, defined in RFC 2616.

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。如有错误或未考虑完全的地方，望不吝赐教。
