Go post重定向的两种方式

1、Location
2、http.Redirect

代码

/index -> /login -> /home

package main
import (
	"fmt"
	"log"
	"net/http"
	"strings"
)


func index(w http.ResponseWriter, r *http.Request) {
	flag := true
	if strings.Contains("/index", r.URL.Path){
		flag = false
	}
	fmt.Println(flag)
	w.Header().Set("Content-Type", "text/html")
	w.Write(indexHTML)
}

var indexHTML = []byte(`
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<button class="button">发送POST请求，登录</button>
<script src="https://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>
<script>
    $(".button").click(
        function (){
            $.post("http://127.0.0.1:9090/login", {}, function (res){
                console.log(res)
            })
        }
    )

</script>

</body>
</html>
`)

func login(w http.ResponseWriter, r *http.Request) {
	// way 1
	fmt.Print(fmt.Sprintf("%v \n", r))
	w.Header().Set("Cache-Control", "must-revalidate, no-store")
	w.Header().Set("Content-Type", " text/html;charset=UTF-8")
	w.Header().Set("Location", "http://127.0.0.1:9090/home")//跳转地址设置
	w.Header().Set("Access-Control-Allow-Origin", "*")
	w.Header().Set("Access-Control-Allow-Credentials", "true")
	w.Header().Set("Access-Control-Allow-Method", "GET,OPTION,POST")
	w.Header().Set("Access-Control-Allow-Headers", "http://127.0.0.1:9090/home")
	w.WriteHeader(301)//关键在这里！
	// way 2
	// http.Redirect(w, r, "/home", 301)

}

func home(w http.ResponseWriter, r *http.Request) {
	w.Header().Set("Content-Type", "text/html")
	w.Write(homeHTML)
}

var homeHTML = []byte(`
<!DOCTYPE html>

                console.log("success !")
            })
        }
    )

</script>

</body>
</html>
`)


func main() {
	http.HandleFunc("/index", index)
	http.HandleFunc("/login", login)
	http.HandleFunc("/home", home)
	err := http.ListenAndServe(":9090", nil) //设置监听的端口
