路由管理器 ServeMux

func main() {

	myMux := http.NewServeMux()
	myMux.HandleFunc("/", func(writer http.ResponseWriter, request *http.Request) {
		_, _ = writer.Write([]byte("hello"))
	})
	_ = http.ListenAndServe(":8089", myMux)
}

func main() {
	myMux := http.NewServeMux()
	myMux.HandleFunc("/", func(writer http.ResponseWriter, request *http.Request) {
		_, _ = writer.Write([]byte("hello"))
	})
	myMux.HandleFunc("/login", func(writer http.ResponseWriter, request *http.Request) {
		_, _ = writer.Write([]byte("这是登录页面"))
	})
	_ = http.ListenAndServe(":8089", myMux)
}

cookie

myMux := http.NewServeMux()
	myMux.HandleFunc("/login", func(writer http.ResponseWriter, request *http.Request) {
		// 获取url上的参数
		userName := request.URL.Query().Get("user_name")
		if userName != "" {
			cookie := &http.Cookie{Name:"userName",Value:userName,Path:"/"}
			http.SetCookie(writer,cookie)
		}

		_, _ = writer.Write([]byte("这是登录页面"))
	})
	_ = http.ListenAndServe(":8089", myMux)

在这里插入图片描述

清除cookie

	myMux.HandleFunc("/logout", func(responseWriter http.ResponseWriter, request *http.Request) {
		// cookie清空
		cookie := &http.Cookie{Name: "userName", Value: "", Path: "/", Expires: time.Now().AddDate(-1, 0, 0)}
		http.SetCookie(responseWriter, cookie)
	})
