Get dan Set Cookie

Cookie merupakan data yang dibuat di server dan dikirimkan ke web browser dan sengaja agar disimpan di sisi client. Penerapan semisal untuk menyimpan data user saat login, sehingga user tidak perlu login lagi setelah saat durasi login berakhir.

package main

import (
	"fmt"
	"net/http"
)

func main() {
	mux := http.NewServeMux()
	mux.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		// request cookie
		key = r.Cookie("key")
		fmt.Println(key)
		// set cookie in response
		cookie1 := new(http.Cookie)
		cookie1.Name = "username"
		cookie1.Value = "member_01"
		cookie2 := new(http.Cookie)
		cookie2.Name = "password"
		cookie2.Value = "Test123"
		http.SetCookie(w, cookie1)
		http.SetCookie(w, cookie2)
	})

	server := http.Server{
		Addr: 	"localhost:5000",
		Handler: mux,
	}

	fmt.Println("Server running on", server.Addr)
	err := server.ListenAndServe()
	if err != nil {
		panic(err)
	}
