如何使用 Ebay SDK 使用 davidtsadler/ebay-sdk-php 进行联合通话？

Question

在问这个问题之前，我是一名公认的 SDK 新手，现在这一切对我来说都是一场斗争，此外，我想我可能还没有完全理解 Ebay 的政策/限制。我不确定什么是“允许的”或“适当的”，所以我不会因为不当使用而被阻止（比如调用太多或类似的事情）。

问题：你能否在另一个请求的循环中调用一个请求，类似于 MySQL/PHP，当你第一次请求 ID 时，它们会遍历它们以返回详细信息？

示例：我想查找目标 ebay-motors 卖家，从这些卖家返回一组编号或关键字搜索列表。 （我相信 SDK 会将此作为一个请求处理 - ItemFilter SellerID / 关键字）

然后，对于每个列表，我希望为每个列表列出兼容车辆（这是每个列表的“第二”循环/请求）。

这是我得到我想要的结果的“逻辑”（或缺乏逻辑）。如果我不能使用循环，但我可以像电子表格一样“加入”兼容列表，那也可以。

//Two responses?..one from each request
$response = $service->findItemsAdvanced($request);

// how to get compatibles from item id in request/response 1 ?//
$response2 = $service-> /* ??? */  ($request2);


// Iterate over the items returned in the response.
foreach ($response->searchResult->item as $item) {
    //an easy var name for reference
    var mylistId = $item->itemId, 
    // lets the see the ID's //
    printf(  
        "(%s) %s\n",
        $item->itemId,
        $item->title
    );

   //maybe the request and response is in the loop???
   // $requestTWO = get compatibles linked to mylistId
   // $responseTWO = return compatibles
   foreach ($responseTWO->searchResult->item as $compats) {
       // print new responses
       printf(  
        "(%s) %s\n",
        $compats->make, 
        $compats->model,
        $compats->year
    );
} 

要求更多细节的新请求似乎有点过头了。

Finding 服务不会返回您需要的兼容性信息。对于退回的每件商品，您必须在购物服务中单独调用 GetSingleItem。
