php - 如何使用亚马逊市场网络服务更新亚马逊卖家的现有数量

Question

如何使用亚马逊市场网络服务更新亚马逊卖家的现有数量。更新产品时，删除旧数量并添加新数量。但我想要现有数量更新。例如。旧数量 5，然后再更新 10 个数量，然后总数量 5+10 = 15。

1. 我的代码。

   require_once '供应商/autoload.php';

   if ($client->validateCredentials()) {

               $product = new MCS\MWSProduct();
   
               $product->sku             = $request['ItemSKU'];
               $product->price           = $request['SalePrice'];
               $product->quantity        = $request['Qty'];
               $product->product_id      = $request['ASINNo'];;
               $product->product_id_type = $request['ProductType'];;
               $product->condition_type  = $request['ConditionType'];;
               $product->title           = $request['Title'];;
               $product->sale_price      = $request['SalePrice'];
   

   //print_r($product); if ($product->validate()) {

                   $result = $client->postProduct($product);  
   
                   if($result){
   
                      $arr['status']   = TRUE; 
                      $arr['submitid'] = $result['FeedSubmissionId'];
                      $info = $client->GetFeedSubmissionResult($result['FeedSubmissionId']);                      
                   }                      
   
               }
   

2. 另一个代码：

$client = new MCS\MWSClient([
                'Marketplace_Id'      => $Amazon_MarketPlaceId,
                'Seller_Id'           => $Amazon_SellerId,
                'Access_Key_ID'       => $Amazon_AWSAccessKeyId,
                'Secret_Access_Key'   => $Amazon_SecretKey,
                'MWSAuthToken'        => $Amazon_MWSAuthToken
            ]);
            if ($client->validateCredentials()) {  
                foreach($request as $key => $value){

                $SKU_Prices[$key]   = $value;
                }

                if(!empty($SKU_Prices)){    
            $result = $client->updatePrice($SKU_Prices);

    if($result){

    $arr['status']      = TRUE; 
    $arr['submitid']    = $result['FeedSubmissionId'];
    }else{

    $arr['status']      = FALSE;
    $arr['submitid']    = 0;    
    }
      }
     }

请让我知道如何更新。
