Question

所以我似乎无法使这段代码正常工作。我在Finding API下使用了一个非常相似的代码，它运行得很好，为Trading API做了适当的更改（端点，标题等），现在它不起作用。在使用eBay API测试工具时，一切似乎都很好，所以我不确定问题是什么。

任何人都可以提供见解吗？ 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.";
}

错误在if ($resp->ack == "Success") {行。正确的字段名称为Ack。 Trading API中的字段与Finding API中的字段不同。将代码更改为if ($resp->Ack == "Success") {应该有效。

Ebay Trading API PHP XML调用失败（确认失败）
