What did you do?

What did you expect to see?

type User struct {
	Id       int
	NickName string
}

switch err.(type) {
	case *json.UnmarshalTypeError:
		unmarshalTypeError := err.(*json.UnmarshalTypeError)
		if unmarshalTypeError.Field == "" {
			err = fmt.Errorf("%s 类型错误，期望类型 %s", unmarshalTypeError.Field, "json")
		} else {
			err = fmt.Errorf("%s 类型错误，期望类型 %s", unmarshalTypeError.Field, unmarshalTypeError.Type.String())
		}
	}

json.decode

unmarshalTypeError.Field value is "id."

this "unmarshalTypeError.Field" is "id." One more point. Is this correct?

What did you see instead?

unmarshalTypeError.Field value is "id." => "id"
