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。
