ssl - PayPal PDT SSL 连接在我的插件域上挂起

Question

在我的 PayPal autoReturn 页面上，使用已知可用的 PHP 脚本来处理支付数据传输，无论我做什么，我都会不断收到此错误消息:"Warning: fgets(): SSL: Connection reset by peer...*(在这一行:'$line = fgets($fp, 1024);'* "

在我问我的问题之前，我只想说我已经尝试了这里和我被建议阅读的任何其他论坛或文章中建议的所有内容，例如将 HTTP 1.0 更改为 HTTP 1.1，使用 $res=stream_get_contents($fp, 1024) 而不是 while 循环 使用 $line = fgets($fp, 1024) 等。我的问题仍然存在。

这就是我认为可能存在的问题(我希望有人能告诉我我是否在正确的轨道上):我的 PDT 自动返回页面在一个附加站点上，我在想当无法识别共享 SSL(对于我在共享服务器上的主域)时，PayPal 挂断。因此，我要求我的虚拟主机专门为我的附加域安装 SSL。

附加域 SSL 问题会不会是我收到警告消息的原因？同样，该消息是:"Warning: fgets(): SSL: Connection reset by peer...*(在行中:'$line = fgets($fp, 1024);'* "

这是我的代码:

 //look if the parameter 'tx' is set in the GET request and that it  does not have a null or empty value
if(isset($_GET['tx']) && ($_GET['tx'])!=null && ($_GET['tx'])!= "") {
    $tx = $_GET['tx'];

    verifyWithPayPal($tx);
}
else {
    exitCode();
}

function verifyWithPayPal($tx) {
    $req = 'cmd=_notify-synch';
    $tx_token = $tx;
    $auth_token = "MY SANDBOX AUTH_TOKEN HERE";
    $req .= "&tx=$tx_token&at=$auth_token";

    // post back to PayPal system to validate
    $header = "POST /cgi-bin/webscr HTTP/1.0\r\n";
    $header .= "Content-Type: application/x-www-form-urlencoded\r\n";
    $header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

    // url for paypal sandbox
    //$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno,   $errstr, 30);    

    // url for payal
    // $fp = fsockopen ('www.paypal.com', 80, $errno, $errstr, 30);
    // If possible, securely post back to paypal using HTTPS
    // Your PHP server will need to be SSL enabled.

     $fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);

    if (!$fp) {
        exitCode();
    } else {
        fputs($fp, $header . $req);        
        // read the body data
        $res = '';
        $headerdone = false;

         while (!feof($fp)) {
            $line = fgets($fp, 1024);
        // $res=stream_get_contents($fp, 1024);
            if (strcmp($line, "\r\n") == 0) {
                // read the header
                $headerdone = true;
            }
            else if ($headerdone) {
                // header has been read. now read the contents
                $res .= $line;
            }
         }

        // parse the data
        $lines = explode("\n", $res);

        $response = array();

        if (strcmp ($lines[0], "SUCCESS") == 0) {

            for ($i=1; $i<count($lines);$i++){
                list($key,$val) = explode("=", $lines[$i]);
                $response[urldecode($key)] = urldecode($val);
            }

            $itemName = $response["item_name"];
            $amount = $response["payment_gross"];
            $myEmail = $response["receiver_email"];
            $userEmailPaypalId = $response["payer_email"];
            $paymentStatus = $response["payment_status"];
            $paypalTxId = $response["txn_id"];
            $currency = $response["mc_currency"];

            // check the payment_status is Completed
            if($paymentStatus!="Completed") {
                payment_complete();
                emailer($userEmailPayPalID);

            } else {
                payment_incomplete($paymentStatus);
            }

            /*
            // check that txn_id has not been previously processed
            checkIfTransactionHasAlreadyBeenProcessed($paypalTxId);
            // check that receiver_email is your Primary PayPal email
            checkThatPaymentIsReceivedAtYourEmailAddress($myEmail);
            // check that payment_amount/payment_currency are correct
            checkPaymentAmountAndCurrency($amount, $currency);
            // process the order
            processOrder();
            } else {
            exitCode();
            */
        }
    }
        fclose ($fp);
}
