Go语言如何处理HTTP身份验证教程示例

client := &http.Client{
    Transport: &http.Transport{},
}
req, err := http.NewRequest("GET", "https://www.example.com", nil)
if err != nil {
    // handle error
}
username := "myusername"
password := "mypassword"
req.SetBasicAuth(username, password)
resp, err := client.Do(req)
if err != nil {
    // handle error
}
defer resp.Body.Close()
// read response

package main
import (
	"fmt"
	"net/http"
	"net/url"
	"strings"
)
func main() {
	// 创建实例
	client := &http.Client{}
	// 设置get方法以及url
	req, err := http.NewRequest("GET", "http://httpbin.org/basic-auth/user/passwd", nil)
	if err != nil {
		fmt.Println("Error creating request:", err)
		return
	}
	// 设置用户名密码header
	username := "user"
	password := "passwd"
	auth := username + ":" + password
	base64Auth := base64.StdEncoding.EncodeToString([]byte(auth))
	req.Header.Add("Authorization", "Basic "+base64Auth)
	// 发送请求
	resp, err := client.Do(req)
	if err != nil {
		fmt.Println("Error sending request:", err)
		return
	}
	defer resp.Body.Close()
	// 检查http状态码
	if resp.StatusCode != http.StatusOK {
		fmt.Println("HTTP Error:", resp.Status)
		return
	}
	// 读取body
	body, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		fmt.Println("Error reading response:", err)
		return
	}
	// 打印body
	fmt.Println("Response Body:", string(body))
}
