php - paypal IPN突然失效(无HTTP响应)

Question

我的 paypal IPN 脚本突然不能用了。在 paypal IPN 历史记录中，IPN 现在失败并且 HTTP 响应代码保持为空。是什么原因造成的以及如何解决？我没有更改任何代码，它只是停止工作了。

这是我的 PHP 代码:

<?php
   //Change these with your information
$paypalmode = ''; //Sandbox for testing or empty ''
$dbusername     = 'xxx'; //db username
$dbpassword     = 'xxx'; //db password
$dbhost     = 'xxx.com'; //db host
$dbname     = 'xxx'; //db name

if($_POST)
{
    if($paypalmode=='sandbox')
    {
        $paypalmode     =   '.sandbox';
    }
    $req = 'cmd=' . urlencode('_notify-validate');
    foreach ($_POST as $key => $value) {
        $value = urlencode(stripslashes($value));
        $req .= "&$key=$value";
    }
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://www'.$paypalmode.'.paypal.com/cgi-bin/webscr');
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: www'.$paypalmode.'.sandbox.paypal.com'));
    $res = curl_exec($ch);
    curl_close($ch);

    if (strcmp ($res, "VERIFIED") == 0)
    {
        $transaction_id = $_POST['txn_id'];
        $ebaytxnid = $_POST['ebay_txn_id1'];
        $payerid = $_POST['payer_id'];
        $firstname = $_POST['first_name'];
        $lastname = $_POST['last_name'];
        $ebayname = $_POST['auction_buyer_id'];
        $email = $_POST['payer_email'];
        $shippingname = $_POST['address_name'];
        $shippingstreet = $_POST['address_street'];
        $shippingcity = $_POST['address_city'];
        $shippingstate = $_POST['address_state'];
        $shippingzip = $_POST['address_zip'];
        $shippingcountry = $_POST['address_country'];
        $shippingcountrycode = $_POST['address_country_code'];
        $currency = $_POST['mc_currency'];
        $paymentfee = $_POST['payment_fee'];
        $total = $_POST['payment_gross'];
        $mcfee = $_POST['mc_fee'];
        $mcgross = $_POST['mc_gross'];
        $ebayitemno = $_POST['item_number'];
        $ebayitemname = $_POST['item_name'];
        $quantity = $_POST['quantity1'];
        $paymentdate = $_POST['payment_date'];
        $mdate= date('Y-m-d h:i:s',strtotime($paymentdate));
        $paymentstatus = $_POST['payment_status'];
        $payerstatus = $_POST['payer_status'];
        $paymenttype = $_POST['payment_type'];
        $addressstatus = $_POST['address_status'];
        $forauction = $_POST['for_auction'];
        $protectioneligibility = $_POST['protection_eligibility'];
        $otherstuff = json_encode($_POST);

        $conn = mysql_connect($dbhost,$dbusername,$dbpassword);
        if (!$conn)
        {
         die('Could not connect: ' . mysql_error());
        }

        mysql_select_db($dbname, $conn);

        // insert in our IPN record table
        $query = "INSERT INTO ibn_table
        (itransaction_id,iebaytxnid,ipayerid,ifirstname,ilastname,iebayname,iemail,ishippingname,ishippingstreet,ishippingcity,ishippingstate,ishippingzip,ishippingcountry,ishippingcountrycode,icurrency,ipaymentfee,itotal,imcfee,imcgross,iebayitemno,iebayitemname,iquantity,itransaction_date,ipaymentstatus,ipayerstatus,ipaymenttype,iaddressstatus,iforauction,iprotectioneligibility,ieverything_else)

        if(!mysql_query($query))
        {
            //mysql error..!
        }
        mysql_close($conn);

    }
}
?>

更新:太平洋夏令时间 2017 年 3 月 15 日上午 11:47 突然恢复工作

我在使用 Godaddy 上的多个托管帐户时也遇到了问题。截至 2017 年 3 月 13 日太平洋标准时间上午 10 点至 12 点左右，后端停止从 Paypal 接收 IPN。

对不起，如果事情没有意义，我是一个自学成才的白痴。我尝试过的事情:删除 SSL 证书添加 SSL 证书手动检查 ipn url (Works)白名单 Paypal IP将所有内容重命名为 https将所有内容重命名为 http四重检查以确保:IPN 未禁用且 IPN url 正确

我发现的有趣的事情:所有托管帐户在 3 年内一切正常。Paypal 沙盒帐户发回 IPN 的完美一切正常。在交易的 IPN 历史记录中，没有 HTTP 状态代码。paypal 根本没有 IPN 访问权限，我这边没有错误或访问日志。问题是在多个托管帐户中只有一个在上个月发生了变化。

让我知道您的想法和事情，希望 Paypal 能够回应或修复它，因为现在所有迹象都指向它们。厌倦了他们的复制粘贴回复。
