krequestFutureList<T> function

Future<List<T>?> krequestFutureList<T>(Future<Response> request(), T fromJsonT(dynamic json), { dynamic onFail(String?, String?, Exception)?, })

请求数据，返回集合

  void loading() async {
    var data = await requestFutureList<ShopDto>(
      () => ApiRepository.get.nearbyMaxsShop(1, 0, 0),
      (json) => ShopDto.fromJson(json),
    );
  }

Implementation

Future<List<T>?> krequestFutureList<T>(
    Future<Response> Function() request, T Function(dynamic json) fromJsonT,
    {Function(String?, String?, Exception)? onFail}) async {
  try {
    var response = await request();
    if (response.statusCode == HttpStatus.ok) {
      var json = response.data;
      var result =
          ResultListDto<T>.fromJson(json, (json) => fromJsonT.call(json));
      if (result.isSuccess()) {
        return result.data;
      } else {
        throw BizException(code: result.errorCode, message: result.message);
      }
    } else {
      KHttpPlatform.get.throwHandler
          ?.handleStatusCode(response.statusCode, onFail: onFail);
    }
  } on Exception catch (ex) {
    KHttpPlatform.get.throwHandler?.handleError(ex, onFail: onFail);
  }
  return null;
}
