使用PHP和CURL的Barclaycard ePDQ API不想工作，没有响应，不确定CURL是否正常工作？

Question

I've been putting this off for a while as I just don't seem to have a clue with what I'm doing. I'm trying to use PHP and Curl to talk to the Barclaycard ePDQ MPI. I've done this before using the HSBC XML API but the Barclaycard ePDQ MPI seems to be giving me a few headaches. I have a form which posts card details/address details and the to a page that contains the following functions Please note that I have SSL set up on the domain, CURL is installed on the server, I had the HSBC XML API working just fine on the same box/URL.

<?php
    function process_card($users_ip, $Temp_Order_ID, $User_NameX, $First_Name, $Surname, $Address_Line1, $Address_Line2, $Town, $Country, $Postcode, $CardNumber, $CardExpiryDate, $issue_node, $CardCVV, $totalCost ) {

    if ($CardCVV == "")
        $cvvindicator = 0;
    else
        $cvvindicator=1;

    global $status;
    //$amount = $amount * 100;

        $xml = '

        $url = "https://secure2.epdq.co.uk:11500";

        $params = array("CLRCMRC_XML" => $xml);
        $params = formatData($params);

        $response = post_to_epdq($url, $xml);   
        $auth_code = strstr($response, "<AuthCode>");

        echo "auth_code=" . $auth_code;

        if ($auth_code <> "") {

            $splt = split("</AuthCode>", $auth_code);

    function post_to_epdq($url, $data) {


        set_time_limit(120);
        $output = array();
        $curlSession = curl_init();
        curl_setopt($curlSession, CURLOPT_URL, $url);
        curl_setopt($curlSession, CURLOPT_PORT, 443);
        curl_setopt($curlSession, CURLOPT_HEADER, 0);
        curl_setopt($curlSession, CURLOPT_POST, 1);
        curl_setopt($curlSession, CURLOPT_POSTFIELDS, $data);
        curl_setopt($curlSession, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curlSession, CURLOPT_TIMEOUT, 60);
        #$response = split(chr(10),curl_exec ($curlSession));

        $response = curl_exec($curlSession);

        if (curl_error($curlSession)) {
            $this->error = curl_error($curlSession);
            return "ERROR";
        }

        curl_close($curlSession);
        return $response;
    }

    function formatData($data) {

        $output = "";
        foreach ($data as $key => $value)
            $output .= "&" . $key . "=" . urlencode($value);
            $output = substr($output, 1);
            return $output;
    }

Needless to say I validate the user input, generate their IP and determine a country code, I then call the above function:

process_card($users_ip,$Temp_Order_ID,$User_NameX,$First_Name,$Surname,$Address_Line1,$Address_Line2,$Town,$Country,$Postcode,$CardNumber, $CardExpiryDate, $issue_node, $CardCVV, $totalCost );

I don't get a response? I'm unsure if the port and url items are incorrect or if the whole CURL request is wrong. Nothing is returned from the request.

Sorry about this being a long post but this is really doing my head in!

Has anyone done this before?

Howdy, after some playing around here's the correct CURL set up you have to do...

I realise that the variables could be better and I should make this as an object but I just want to get a quick answer up there. The script also needs to sift through the different accept and error messages but this is what I've got so far...

$ch = curl_init();
$url = "https://secure2.epdq.co.uk:11500"; // Don't need to add curl_setopt($curlSession, CURLOPT_PORT, 443); as port is included
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $vars); // $vars is your XML 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

$data = curl_exec($ch);
curl_close ($ch);

$xml = new domDocument;
$xml->loadXML($data);

if (!$xml) {
    echo 'Error while parsing the document - Please Contact to determine if payment has gone though';
    exit;
}

$x = $xml->getElementsByTagName( "CcErrCode" );
$approved = $x->item(0)->nodeValue;

$xx = $xml->getElementsByTagName( "CcReturnMsg" );
$CcReturnMsg = $xx->item(0)->nodeValue;

if($approved) {

// the card is valid.
    $y = $xml->getElementsByTagName( "Id" );
    $BCardId = $y->item(1)->nodeValue;

    $z = $xml->getElementsByTagName( "MessageList" );
    $MessageList = $z->item(0)->nodeValue;

    $zz = $xml->getElementsByTagName( "AvsRespCode" );
    $AvsRespCode = $zz->item(0)->nodeValue;

    $zzz = $xml->getElementsByTagName( "AvsDisplay" );
    $AvsDisplay = $zzz->item(0)->nodeValue;

    $zzzz = $xml->getElementsByTagName( "ProcReturnMsg" );
    $ProcReturnMsg = $zzzz->item(0)->nodeValue;

     if($approved == "1"){
       echo "approved!<br />";
       echo "BCardId: " . $BCardId . ", MessageList=" . $MessageList . ", " . $AvsRespCode . ", " . $AvsDisplay . ", " . $ProcReturnMsg;
       die();
     }else{
       // raise that it's been partially accepted, 
       echo "partially approved";
       echo "BCardId: " . $BCardId . ", MessageList=" . $MessageList . ", " . $AvsRespCode . ", " . $AvsDisplay . ", " . $ProcReturnMsg;
       die();
     }

}else{
   echo "you have been completely knocked back";
   $zzzzz = $xml->getElementsByTagName( "Text" );
   $BCard_Text = $zzzzz->item(0)->nodeValue;
   echo "The reason:" . $BCard_Text;    
   die();
}

hope this helps other people who have to set this up!
