我无法为 EbaySDK 创建标签，因此 Ebay API 可能会产生误导。SDK 参考如下。
为什么有些请求需要“输入”，在哪里可以找到？SDK 注释似乎并不清楚每个“呼叫类型”所需的内容。
按照http://devbay.net/sdk/guides/getting-started/basic-usage.html#working-with-responses中的示例，我正在尝试获取已售商品的列表。由于 Ebay 只保留 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（而且显然不完整）
$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。
看来我不是在要求什么，但我不知道。
