golang 设置web请求状态码
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"))
}
