小村上空升起袅袅炊烟，好像一个身穿白纱的少女在翩翩起舞，在夕阳的照耀下婀娜多姿。
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：//www.haodaima.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 /hello HTTP/1.1
Host: 127.0.0.1:12345
<==
HTTP/1.1 401 Unauthorized
WWW-Authenticate: Basic realm="Dotcoo User Login"
==>
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
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("WWW-Authenticate", `Basic realm="Dotcoo User Login"`)
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。
到此这篇关于golang的HTTP基本认证机制实例详解就介绍到这了。心绷得太紧，就容易烦躁。尝试给自己一份松弛的柔软，对暂时不顺心的事，抱以理解与包容。当你的心不再那么紧绷，你会发现你与他人之间多了几分宽和，与世界也会多了几分契合。更多相关golang的HTTP基本认证机制实例详解内容请查看相关栏目，小编编辑不易，再次感谢大家的支持！
