Php 尝试将PDF发票上载到Amazon MWS时出现错误：“；上传发票时请仅提供一个有效的市场“；

我目前正在研究如何使用php/curl将我自己的发票pdf文件上传到Amazon MWS： 1.）使用操作：SubmitFeed和FeedType:Upload_VAT_INVOICE将pdf上载到Amazon MWS 这是对FeedSubmissionId的肯定回应

2.）获取Feed提交结果，FeedSubmissionId报告错误79523“上传发票时，请仅提供一个有效市场。”

因此，我假设我的上传工作不正常，但我找不到错误

错误代码在Amazon的PDF文件第21页中描述：

到目前为止，我已经花了两天时间试图解决这个问题，但我在谷歌上找不到任何关于它的信息。希望这里有人能帮我。谢谢

代码如下：

此提要中没有可发布的XML。FeedContent（

CURLOPT\u POSTFIELDS

）是PDF的内容（

$PDF\u feed

）

您是否发布到正确的端点？您的marketplace ID表示使用mws eu端点的德国：我还希望参数名称应该是单数，

MarketplaceId

，因为

MarketplaceIdList

表示多个端点。我已经尝试了几个端点，“mws.amazonservices.de”正在工作。对于参数“MarketplaceId”，我已经尝试了我可以在网上找到的所有不同格式：

“Marketplace”、“MarketplaceId”、“MarketplaceList.Id”、“MarketplaceId.Id.1”

，这似乎没有任何区别。在端点

mws.amazonservices.de

和

mws eu.amazonservices.com

之间似乎没有功能上的区别。我已经找到了解决方案并更新了代码。解决方案：Marketplace Id参数名称必须是

MarketplaceIdList.Id.1

您能在回答中编写工作代码吗$amazon\u提要也没有定义
