Amazon MWS _GET_MERCHANT_LISTINGS_DATA_为空

Question

当我调用GetReport时，我只得到制表符分隔的响应的头。但是，当我使用便签簿进行RequestReport、RequestReportList操作时，使用RequestId获取GeneratedReportId，然后使用该Id获取GetReport。我得到了预期的结果。

有人知道为什么我的代码不能像scrathpad那样拉取报表吗？

            RequestReportRequest request = new RequestReportRequest();
            request.Merchant = settings.SellerId;
            request.MarketplaceIdList = new IdList();
            request.MarketplaceIdList.Id = new List<string>(new string[] { settings.MarketplaceId });
            request.ReportType = "_GET_MERCHANT_LISTINGS_DATA_";

            RequestReportResponse requestResponse = _mws.RequestReport(request);
            Thread.Sleep(15000);
            Console.WriteLine(requestResponse.RequestReportResult.ReportRequestInfo.ReportProcessingStatus);
            GetReportRequestListRequest reportRequestListRequest = new GetReportRequestListRequest();

            reportRequestListRequest.Merchant = settings.SellerId;
            List<ReportRequestInfo> requestInfos = new List<ReportRequestInfo>();

            GetReportRequestListResponse reportRequestListResponse = new GetReportRequestListResponse();
            reportRequestListResponse = _mws.GetReportRequestList(reportRequestListRequest);
            GetReportRequestListResult reportRequestListResult = new GetReportRequestListResult();
            reportRequestListResult = reportRequestListResponse.GetReportRequestListResult;
            requestInfos = reportRequestListResult.ReportRequestInfo;

            while (requestInfos[0].ReportProcessingStatus.ToString() != "_DONE_")
            {
                Thread.Sleep(20000);
                reportRequestListResponse = _mws.GetReportRequestList(reportRequestListRequest);
                reportRequestListResult = reportRequestListResponse.GetReportRequestListResult;
                requestInfos = reportRequestListResult.ReportRequestInfo;

            }

            GetReportListRequest listRequest = new GetReportListRequest();
            listRequest.Merchant = settings.SellerId;
            listRequest.ReportRequestIdList = new IdList();
            listRequest.ReportRequestIdList.Id.Add(requestResponse.RequestReportResult.ReportRequestInfo.ReportRequestId);

            GetReportListResponse listResponse = _mws.GetReportList(listRequest);

            GetReportListResult getReportListResult = listResponse.GetReportListResult;

            GetReportRequest reportRequest = new GetReportRequest();
            reportRequest.Merchant = settings.SellerId;
            reportRequest.WithReportId(getReportListResult.ReportInfo[0].ReportId);

            GetReportResponse reportResponse = new GetReportResponse();
            string fileName = dataPath + "\\report-" + getReportListResult.ReportInfo[0].ReportId + ".txt";
            reportRequest.Report = File.Open(fileName, FileMode.OpenOrCreate, FileAccess.ReadWrite); 
            reportResponse = _mws.GetReport(reportRequest); 

Answer 1

我从ReportRequest中删除了MarketplaceId，它工作正常。我不知道为什么它没有拉出指定的报告，但它在没有信息的情况下工作。

从上面的代码中删除了这两行。

        request.MarketplaceIdList = new IdList();
        request.MarketplaceIdList.Id = new List<string>(new string[] { settings.MarketplaceId });
