亚马逊 sp-api更新库存 feed 方式，xsd 验证xml

更新库存遇到的坑，  xml格式不对，因为输出的测试xml ，后面又加了点字符串，因为这个错误，耽误我好几天。。。下次测试结果时候，一定要等变量完全停止定义的后面 输出

        if($debug) echo htmlentities($xml);
        $feedContents = $xml;

        // 原来这个多了一行，导致了错误
        //$xml .= '</AmazonEnvelope>';

feed 更新方式

1，createFeedDocument 返回 

feedDocumentId

(

POST_INVENTORY_AVAILABILITY_DATA

)

2. uploadxml

3 createfeed

检测方式

1 getFeed

2 

getFeedDocument

3 根据返回的url ,打开这个网址 看feed的执行结果

说明1 。inventory 的xml

<?xml version="1.0" encoding="UTF-8"?>
<AmazonEnvelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="amzn-envelope.xsd">
  <Header>
    <DocumentVersion>1.01</DocumentVersion>
    <MerchantIdentifier>A。。。。。。X</MerchantIdentifier>
  </Header>
  <MessageType>Inventory</MessageType>
  <Message>
    <MessageID>1</MessageID>
    <OperationType>Update</OperationType>
    <Inventory>
      <SKU>SY...</SKU>
      <FulfillmentCenterID>DEFAULT</FulfillmentCenterID>
      <Quantity>3</Quantity>
    </Inventory>
  </Message>
</AmazonEnvelope>

2 xsd的位置

3 根据xsd 判断xml是否符合格式

最后演示代码

use SellingPartnerApi\Api\FeedsV20210630Api as FeedsApi;
use SellingPartnerApi\FeedType;
use SellingPartnerApi\Model\FeedsV20210630 as Feeds;
。。。。。




    //POST_INVENTORY_AVAILABILITY_DATA 原来用POST_PRODUCT_DATA 无效
        $feedType = FeedType::POST_INVENTORY_AVAILABILITY_DATA;
        $feedsApi = new FeedsApi($config);


         // Create feed document
         $createFeedDocSpec = new Feeds\CreateFeedDocumentSpecification(['content_type' => $feedType['contentType']]);
         $feedDocumentInfo = $feedsApi->createFeedDocument($createFeedDocSpec);
         $feedDocumentId = $feedDocumentInfo->getFeedDocumentId();
、。。。。。
