golang的HTTP基本认证机制实例详解
本文实例讲述了golang的HTTP基本认证机制。分享给大家供大家参考,具体如下:
看了<<http权威指南>>第12章HTTP基本认证机制(本站下载地址:https://www.nhooo.com/books/93254.html),感觉讲的蛮详细的,写了一个小小例子测试.
请求响应过程:
==> GET/helloHTTP/1.1 Host:127.0.0.1:12345 <== HTTP/1.1401Unauthorized WWW-Authenticate:Basicrealm="DotcooUserLogin" ==> GET/helloHTTP/1.1 Host:127.0.0.1:12345 Authorization:BasicYWRtaW46YWRtaW5wd2Q= <== HTTP/1.1200OK Content-Type:text/plain;charset=utf-8
golangHTTP基本认证机制的实现
packagemain import( "fmt" "io" "net/http" "log" "encoding/base64" "strings" ) //helloworld,thewebserver funcHelloServer(whttp.ResponseWriter,req*http.Request){ auth:=req.Header.Get("Authorization") ifauth==""{ w.Header().Set("WWW-Authenticate",`Basicrealm="DotcooUserLogin"`) w.WriteHeader(http.StatusUnauthorized) return } fmt.Println(auth) auths:=strings.SplitN(auth,"",2) iflen(auths)!=2{ fmt.Println("error") return } authMethod:=auths[0] authB64:=auths[1] switchauthMethod{ case"Basic": authstr,err:=base64.StdEncoding.DecodeString(authB64) iferr!=nil{ fmt.Println(err) io.WriteString(w,"Unauthorized!\n") return } fmt.Println(string(authstr)) userPwd:=strings.SplitN(string(authstr),":",2) iflen(userPwd)!=2{ fmt.Println("error") return } username:=userPwd[0] password:=userPwd[1] fmt.Println("Username:",username) fmt.Println("Password:",password) fmt.Println() default: fmt.Println("error") return } io.WriteString(w,"hello,world!\n") } funcmain(){ http.HandleFunc("/hello",HelloServer) err:=http.ListenAndServe(":12345",nil) iferr!=nil{ log.Fatal("ListenAndServe:",err) } }
希望本文所述对大家Go语言程序设计有所帮助。
