gin-jwt

1. Authenticator 回傳的 data
2. data 會丟入到 PayloadFunc
3. PayloadFunc 整理資料寫入 MapClaims
4. Authorizator 再拿 MapClaims 資料出來判斷

新版和舊版有地方不同

type xxxxx struct{

     aaaaaaa:string

}

1、
Authenticator: func(userId string, password string, c *gin.Context) (interface{}, bool) {

return xxxxx{aaaaaaa: ooooxxxx}   or   string

2、

PayloadFunc: func(data interface{})   jwt.MapClaims {

if v, ok := data.(xxxxx); ok {
  id = data.(xxxxx).aaaaaaa
}

return jwt.MapClaims{“aaaaaaa”: ooooxxxx, “bbbbbbb”: ooooxxxx}

3、

Authorizator: func(data interface{}, c *gin.Context) bool {

claims := jwt.ExtractClaims(c)
id := claims[“aaaaaaa”].(string)

！注意！  Here data is string   fmt.Println(reflect.TypeOf(data))
