【问题描述】：
所以我似乎无法让这段代码正常工作。我在 Find API 下使用了一个非常相似的代码，效果很好，对 Trading API 进行了适当的更改（端点、标题等），但现在它不起作用了。在使用 eBay API 测试工具时，一切似乎都很好，所以我不确定问题可能是什么。
谁能提供见解？ ack 返回失败而不是成功。我的 PHP 启用了 curl，这也不是问题。提前谢谢！
<?php
error_reporting(E_ALL); // Turn on all errors, warnings, and notices for easier debugging
// API request variables
$endpoint = 'https://api.ebay.com/ws/api.dll'; // URL to call
$query = 'username'; // Supply your own query keywords as needed
// Construct the findItemsByKeywords POST call
$resp = simplexml_load_string(constructPostCallAndGetResponse($endpoint, $query));
// Check to see if the call was successful, else print an error
if ($resp->ack == "Success") {
$results = ''; // Initialize the $results variable
// Parse the desired information from the response
foreach($resp->searchResult->item as $item) {
$pic = $item->galleryURL;
$link = $item->viewItemURL;
$price = $item->sellingStatus->currentPrice;
$title = $item->title;
// Build the desired HTML code for each searchResult.item node and append it to $results
$results .= "<tr><td><img src=\"$pic\"></td><td>$price</td><td><a href=\"$link\">$title</a></td></tr>";
}
}
else { // If the response does not indicate 'Success,' print an error
$results = "<h3>Oops! The request was not successful.";
}
