今天项目中要将map存入cookie，于是大象哥研究了下json和base64，写了个小例子

一、将map存入cookie

//要存入cookie的map
your := map[string]string{}
your["isuser"] = isuser
your["username"] = username
your["password"] = d.Strtomd5(password)
//将map转成json  转换后的是[]byte，需要string(your_byte)后就是json了
your_byte,_ := json.Marshal(your)
//将json base64一下
b64 := base64.NewEncoding("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/")
your_string := b64.EncodeToString(your_byte)
fmt.Println(your_string)
//第二种base64的方式
your_string = base64.StdEncoding.EncodeToString(your_byte)
fmt.Println(your_string)
//存储cookie
this.Ctx.SetCookie("your",your_string)

//读取cookie中的变量
your_string := this.Ctx.Input.Cookie("your")
//解析成json
b64 := base64.NewEncoding("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/")
your_to_byte,_ := b64.DecodeString(your_string)
your := string(your_to_byte)
fmt.println(your)
