下面的教程展示了如何将数据显示为HTML，我只需要显示XML的响应，而不是解析它。我试图找到解决办法，但没有任何运气。如有任何帮助，不胜感激。
<?php
$endpoint = 'http://svcs.ebay.com/services/search/FindingService/v1'; // URL to call
$query = 'iphone'; // Supply your own query keywords as needed
// Construct the findItemsByKeywords POST call
// Load the call and capture the response returned by the eBay API
// The constructCallAndGetResponse function is defined below
$resp = simplexml_load_string(constructPostCallAndGetResponse($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) {
$link = $item->viewItemURL;
$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><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";
$results .= "AppID for the Production environment.</h3>";
}
function constructPostCallAndGetResponse($endpoint, $query) {
global $xmlrequest;
// Create the XML request to be POSTed
$xmlrequest = "<?xml version='"1.0'" encoding='"utf-8'"?>'n";
$xmlrequest .= "<findItemsByKeywordsRequest
xmlns='"http://www.ebay.com/marketplace/search/v1/services'">'n";
$xmlrequest .= "<keywords>";
$xmlrequest .= $query;
$xmlrequest .= "</keywords>'n";
$xmlrequest .= "<paginationInput>'n
<entriesPerPage>3</entriesPerPage>'n</paginationInput>'n";
$xmlrequest .= "</findItemsByKeywordsRequest>";
// Set up the HTTP headers
$headers = array(
'X-EBAY-SOA-OPERATION-NAME: findItemsByKeywords',
'X-EBAY-SOA-SERVICE-VERSION: 1.3.0',
'X-EBAY-SOA-REQUEST-DATA-FORMAT: XML',
'X-EBAY-SOA-GLOBAL-ID: EBAY-GB',
'X-EBAY-SOA-SECURITY-APPNAME: ******',
'Content-Type: text/xml;charset=utf-8',
);
$session = curl_init($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, $xmlrequest); // set the body of the POST
curl_setopt($session, CURLOPT_RETURNTRANSFER, true); //
$responsexml = curl_exec($session); // send the request
curl_close($session); // close the session
return $responsexml; // returns a string
} // End of constructPostCallAndGetResponse function
?>
试着改变这个(为清晰起见，已换行):
$resp = simplexml_load_string(
constructPostCallAndGetResponse($endpoint, $query)
);
:
$xmlString = constructPostCallAndGetResponse($endpoint, $query);
$resp = simplexml_load_string($xmlString);
// Now you have your raw XML to play with
echo htmlentities($xmlString);
// The XML document $resp is available too, if you wish to do
// something with that
原始程序立即将XML响应提供给XML解析器，并用它创建一个XML对象(有关详细信息，请参阅PHP手册中的SimpleXML)。在这里，我们将这两个调用分开，因此XML字符串现在保存在一个中间变量中。
