asp.net - 从 Expedia 获取酒店和房间图片列表

Question

使用 Asp.Net，我想从 Expedia 获取酒店和所有相应的属性，例如酒店和房间图像。

它给出了图像之外的所有属性。我想通过酒店列表服务获取酒店和房间图片。我该怎么做才能实现这一目标？这是我的要求

var serviceClient = new HotelServicesClient("ExpediaServicePort");

            var serviceRequest = new HotelListRequest();
            serviceRequest.apiKey = _apiKey;
            serviceRequest.locale = _culture == "tr" ? LocaleType.tr_TR : LocaleType.en_US;
            serviceRequest.localeSpecified = true;
            serviceRequest.currencyCode = _culture == "tr" ? "TRY" : "EUR";
            serviceRequest.supplierType = "E";
            serviceRequest.searchRadius = 100;
            serviceRequest.searchRadiusSpecified = true;
            serviceRequest.searchRadiusUnit = SearchRadiusUnitType.KM;
            serviceRequest.searchRadiusUnitSpecified = true;
            serviceRequest.arrivalDate = hotelListRequest.ArrivalAt.ToString("MM/dd/yyyy", CultureInfo.InvariantCulture);
            serviceRequest.departureDate = hotelListRequest.DepartureAt.ToString("MM/dd/yyyy", CultureInfo.InvariantCulture);
            serviceRequest.RoomGroup = new[] { new Room { numberOfAdults = hotelListRequest.AdultCount, numberOfChildren = hotelListRequest.ChildCount } };
            serviceRequest.sort = SortType.PRICE;
            serviceRequest.sortSpecified = true;
            serviceRequest.numberOfResults = 50;
            serviceRequest.numberOfResultsSpecified = true;

            if (hotelListRequest.Latitude.HasValue && hotelListRequest.Longitude.HasValue)
            {
                serviceRequest.latitude = (float)hotelListRequest.Latitude.Value;
                serviceRequest.latitudeSpecified = true;
                serviceRequest.longitude = (float)hotelListRequest.Longitude.Value;
                serviceRequest.longitudeSpecified = true;
            }
            else
            {
                serviceRequest.destinationString = hotelListRequest.City;
            }

            var hotelListResponse = new Entity.HotelList.HotelListResponse();

            var response = serviceClient.getList(serviceRequest);

            if (response.EanWsError != null)
                throw new Exception(response.EanWsError.verboseMessage);

            hotelListResponse.CacheKey = response.cacheKey;
            hotelListResponse.CacheLocation = response.cacheLocation;
            hotelListResponse.HasMore = response.moreResultsAvailable;

            if (true)
            {
                foreach (var serviceHotel in response.HotelList.HotelSummary)
                {
                    var hotel =

                        new Entity.Hotel
                            {
                                RefID = serviceHotel.hotelId,
                                Url = hotelUrl(serviceHotel.hotelId, _htmlDecodeFunc(serviceHotel.name)),  .......

Answer 1

LIST api 不提供酒店图片，仅提供缩略图。
有三个地方可以获取图片，INFO(酒店图片)、ROOMIMAGES 和 AVAIL(房间图片)。

使用 LIST(或任何 api)提供的缩略图，您还可以通过替换最后的“_b”来获得各种格式。 '_l.' (风景),'_s.' (小)，或 .... 此处列出了完整的替换值:

请记住，您在生产中被限制为每秒 40 个请求，因此获取 LIST 结果的所有图像会很快消耗掉它。如果您使用的是他们数据库文件的本地版本，则可以从 LIST 中获取所有图像，而无需 ping 其 API。上面的第一个链接包含该文件的下载位置，只需要一些本地(无)SQL 集成。
