)

type User struct {
	Id string
}

func (u *User) UnmarshalJSON(data []byte) error {
	var um map[string]string
	err := json.Unmarshal(data, &um)
	if err != nil {
		return err
	}

	if v, ok := um["uid"]; ok {
		u.Id = v
	}
	return nil
}

func main() {
	data := `{"uid": "123", "uname": "456"}`
	var u User
	err := gjson.New(data).Scan(&u)
	if err != nil {

@wlynxg Hi, the gjson does not support json.Unmarshaler as the json string you passed to gjson.New was already converted to map[string]interface{} for hierarchical access feature.
