从Ebay SDK销售中获取销售商品 - 获取＆＃34;缺少所需的输入元素＆＃34;错误

Question

我无法为EbaySDK创建标记，因此Ebay API可能会产生误导。 SDK参考文献如下。

为什么有些请求需要＆＃34;输入＆＃34;他们在哪里可以找到？ SDK注意事项似乎并不清楚每个＆＃34;呼叫类型＆＃34;所需的内容。

根据http://devbay.net/sdk/guides/getting-started/basic-usage.html#working-with-responses的示例，我试图获取已售商品的清单。由于Ebay仅保留90天的数据，因此我对我的请求没有任何限制。

他们的示例请求是：

// Create the API request object.
 $request = new Types\FindItemsByKeywordsRequest();
// Assign the keywords.
 $request->keywords = 'Harry Potter';
// Output the response from the API.
  if ($response->ack !== 'Success') {
     foreach ($response->errorMessage->error as $error) {
       printf("Error: %s\n", $error->message);
     }
    } else {
      foreach ($response->searchResult->item as $item) {
         printf("(%s) %s:%.2f\n", $item->itemId, $item->title, $item->sellingStatus->currentPrice->value);
     }
  }

我的更简单（显然不完整）

$request = new Types\GetItemStatusRequestType;
$response = $service->getItemStatus();
if ($response->Ack !== 'Success') {
    if (isset($response->Errors)) {
        foreach ($response->Errors as $error) {
            printf("Error: %s\n", $error->ShortMessage);
        }
    }
} else {
    print_r($response->getItemStatus); //should return all avail values (works with other types of requests)
}

这是令人讨厌的错误

错误：缺少必需的输入元素。

似乎我没有问过要求，但我不知道。

GetItemStatus调用要求您提供ItemID。请参阅以下API参考：GetItemStatus

您声明您正在寻找销售历史记录。我不相信这是你应该使用的电话。这是一个似乎位于购物API中的函数调用，它更像是一个产品搜索工具。

你可能想要使用＆＃39; GetOrders＆＃39;如果您希望获得特定帐户销售历史记录，请拨打API电话。请参阅以下内容：GetOrders
