亚马逊MWS请求报告API

Question

我使用亚马逊MWS请求报告API来请求报告，但API返回的响应是

服务响应

    GetReportRequestListResponse
        GetReportRequestListResult
            NextToken
                string
            HasNext

            ReportRequestInfo
                ReportRequestId
                    string
                ReportType
                    string
                StartDate

在上面的结果中没有值只有值类型我从https://developer.amazonservices.com/doc/bde/reports/v20090101/php.html/187-0944446-1656165下载客户端库

以下是我用来调用它的代码：

$serviceUrl = "mws.amazonservices.com";; 

$config = array(
    'ServiceURL' => $serviceUrl, 
    'ProxyHost' => null, 
    'ProxyPort' => -1, 
    'MaxErrorRetry' => 3, 
); 

$marketplaceIdArray = array("Id" => array(MARKETPLACE_ID)); 
$request = new MarketplaceWebService_Model_RequestReportRequest(); 
$request->setMarketplaceIdList($marketplaceIdArray); 
$request->setMerchant(MERCHANT_ID); 
$request->setReportType('GET_MERCHANT_LISTINGS_DATA'); 
$request->setReportOptions('ShowSalesChannel=true'); 
$requestReportArray = invokeRequestReport($service, $request);

任何想法？
