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 >第12章HTTP基本认证机制（本站下载地址：//HdhCmsTestjb51.net/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:
复制代码 代码如下:
==>
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
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("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。
