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：//）,感觉讲的蛮详细的,写了一个小小例子测试.

　　请求响应过程:
复制代码 代码如下:==>
GET /hello HTTP/1.1
Host: 127.0.0.1:12345
<==
HTTP/1.1 401 Unauthorized

==>
GET /hello HTTP/1.1
Host: 127.0.0.1:12345
Authorization: Basic YWRtaW46YWRtaW5wd2Q=
<==
HTTP/1.1 200 OK
Content-Type: text/plain; charset=utf-8

　　golang HTTP基本认证机制的实现
复制代码 代码如下:package main
import (
fmt
io
net/http
log
encoding/base64
strings
)
// hello world, the web server
func HelloServer(w http.ResponseWriter, req *http.Request) {
auth := req.Header.Get(Authorization)
if auth == {
w.Header().Set(
w.WriteHeader(http.StatusUnauthorized)
return
}
fmt.Println(auth)
auths := strings.SplitN(auth, , 2)
if len(auths) != 2 {
fmt.Println(error)
return
}
authMethod := auths[0]
authB64 := auths[1]
switch authMethod {
case Basic:
authstr, err := base64.StdEncoding.DecodeString(authB64)
if err != nil {
fmt.Println(err)
io.WriteString(w, Unauthorized!\n)
return
}
fmt.Println(string(authstr))
userPwd := strings.SplitN(string(authstr), :, 2)
if len(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)
}
func main() {
http.HandleFunc(/hello, HelloServer)
err := http.ListenAndServe(:12345, nil)
if err != 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。
