使用eBay Shopping API和PHP时遇到问题（GetSingleItem请求）

Question

我已经阅读了很多文档，并尝试了在Internet上找到的解决方案，并且我正努力使用GetSingleItem请求从eBay Shopping API中检索所需的数据。我相信我已经根据文档中的示例正确设置了标头和xml请求，但是我无法弄清楚如何实际发送请求并检索xml响应。有人可以帮助我进行下一步吗？

我实际上如何发送请求并检索响应？

我的标头和xml请求看起来像这样：

    // Create headers
    $headers = array 
    (
        'X-EBAY-API-APP-ID: ' . $app_id,
        'X-EBAY-API-SITE-ID: ' . $site_id,
        'X-EBAY-API-CALL-NAME: ' . $call_name,
        'X-EBAY-API-VERSION: ' . $version,          
        'X-EBAY-API-REQUEST-ENCODING: ' . $encoding,
    );

    // Generate XML request
    $xml_request = '<?xml version="1.0" encoding="utf-8"?>\n';
    $xml_request .= '<GetSingleItemRequest xmlns="urn:ebay:apis:eBLBaseComponents">\n';
    $xml_request .= '<ItemID>283814879195</ItemID>\n';
    $xml_request .= '<IncludeSelector>Details</IncludeSelector>\n';
    $xml_request .= '</GetSingleItemRequest>';

下一步是什么？

[如果有帮助，这是到目前为止我已经尝试过的完整代码，但是当我尝试使用simplexml_load_string时，我收到“无法加载”的信息。为了安全起见，我也删除了我的app_id：

<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');

function getItem($itemID) {
    $endpoint = 'https://open.api.ebay.com/shopping';

    $app_id = 'XXXXXXXXXXX';
    $site_id = '3';
    $call_name = 'GetSingleItem';
    $version = '863';
    $encoding = 'xml';

    // Create headers to send with CURL request.
    $headers = array 
    (
        'X-EBAY-API-APP-ID: ' . $app_id,
        'X-EBAY-API-SITE-ID: ' . $site_id,
        'X-EBAY-API-CALL-NAME: ' . $call_name,
        'X-EBAY-API-VERSION: ' . $version,          
        'X-EBAY-API-REQUEST-ENCODING: ' . $encoding,
    );

    // Generate XML request
    $xml_request = '<?xml version="1.0" encoding="utf-8"?>\n';
    $xml_request .= '<GetSingleItemRequest xmlns="urn:ebay:apis:eBLBaseComponents">\n';
    $xml_request .= '<ItemID>283814879195</ItemID>\n';
    $xml_request .= '<IncludeSelector>Details</IncludeSelector>\n';
    $xml_request .= '</GetSingleItemRequest>';

    $session  = curl_init($endpoint);                       // create a curl session
    curl_setopt($session, CURLOPT_POST, true);              // POST request type
    curl_setopt($session, CURLOPT_HTTPHEADER, $headers);    // set headers using $headers array
    curl_setopt($session, CURLOPT_POSTFIELDS, $xml_request); // set the body of the POST
    curl_setopt($session, CURLOPT_RETURNTRANSFER, true);    // return values as a string, not to std out

    $responsexml = curl_exec($session);                     // send the request
    curl_close($session);                                   // close the session    

    return $responsexml;                                    // returns a string
}


$itemID = '283814879195';
$resp = simplexml_load_string(getItem($itemID)) or die("Failed to load");

print($resp->Item->ItemID);

?>

我遇到了同样的问题。完成后，我将在我的Github上公开发布我的项目，所以就到这里。

注意，ItemID正在传递到函数中。如果打算对itemID进行硬编码，则可以忽略代码的第一位中的GET。

$ItemID = $_GET['itemid'];
itemDetails($ItemID);

然后

function itemDetails($ItemID) {
$url = 'https://open.api.ebay.com/shopping';
$app_id = '[ADD YOUR APP ID]';
$site_id = '0';
$call_name = 'GetSingleItem';
$version = '863';
$encoding = 'xml';

$xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>";
$xml.= "<GetSingleItemRequest xmlns=\"urn:ebay:apis:eBLBaseComponents\">";
$xml .= "<ItemID>".$ItemID."</ItemID>";
$xml .= "</GetSingleItemRequest>";

    $headers = array(
    'X-EBAY-API-APP-ID:'.$app_id,
    'X-EBAY-API-SITE-ID:'.$site_id,
    'X-EBAY-API-CALL-NAME:'.$call_name,
    'X-EBAY-API-VERSION:'.$version,          
    'X-EBAY-API-REQUEST-ENCODING:'.$encoding,
    'Content-type:text/xml;charset=utf-8'
    );

    $connection = curl_init();
    curl_setopt($connection, CURLOPT_URL, $url); 
    curl_setopt($connection, CURLOPT_HTTPHEADER, $headers); 
    curl_setopt($connection, CURLOPT_POST, 1);
    curl_setopt($connection, CURLOPT_POSTFIELDS, $xml); 
    curl_setopt($connection, CURLOPT_RETURNTRANSFER, 1); 

    $result = curl_exec($connection); 
    echo $result;
    curl_close($connection);
}

希望这会有所帮助！
