PayPal IPN和fsockopen

标签： php paypal paypal-ipn fsockopen

我无法使用cURL，我的网站主机上安装的无法更改的版本不支持TLS。

我正在尝试使用fsockopen来查看我是否能够使用IPN。

它只是挂起，浏览器抛出连接超时。

PHP 7，启用open_ssl 

<?php
    header('HTTP/1.1 200 OK'); 

    $item_name        = $_POST['item_name'];
    $item_number      = $_POST['item_number'];
    $payment_status   = $_POST['payment_status'];
    $payment_amount   = $_POST['mc_gross'];
    $payment_currency = $_POST['mc_currency'];
    $txn_id           = $_POST['txn_id'];
    $receiver_email   = $_POST['receiver_email'];
    $payer_email      = $_POST['payer_email'];

    $req = 'cmd=_notify-validate';               // Add 'cmd=_notify-validate' to beginning of the acknowledgement
    foreach ($_POST as $key => $value) {         // Loop through the notification NV pairs
        $value = urlencode(stripslashes($value));  // Encode these values
        $req  .= "&$key=$value";                   // Add the NV pairs to the acknowledgement
    }

    // Set up the acknowledgement request headers
    $header  = "POST /cgi-bin/webscr HTTP/1.1\r\n";                    // HTTP POST request
    $header .= "Content-Type: application/x-www-form-urlencoded\r\n";
    $header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

    // Open a socket for the acknowledgement request
     $fp = fsockopen('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);

    // Send the HTTP POST request back to PayPal for validation
    fputs($fp, $header . $req);

    while (!feof($fp)) {                     // While not EOF

    $res = trim(fgets ($fp, 1024));

    if (strcmp ($res, "VERIFIED") == 0) {  // Response contains VERIFIED - process notification

      file_put_contents('./log_'.date("j.n.Y").'.txt', 'VERIFIED', FILE_APPEND);
    } 
    else if (strcmp ($res, "INVALID") == 0) { Response contains INVALID - reject notification
        file_put_contents('./log_'.date("j.n.Y").'.txt', 'INVALID', FILE_APPEND);
    }
  }
  //close
  fclose($fp);
?>

更新

因此，我的当前代码似乎存在问题。我使用以下内容来查看是否可以与PayPal通信。

<?php

$site = "sandbox.paypal.com";//works
$port = 443;

$fp = fsockopen($site, $port, $errno, $errstr, 30);

if(!$fp){
  echo "<b>The port is NOT open!</b>";
}else{
  echo "<b>The port is open!</b>";
  fclose($fp);
}

?>

结果为The port is open!

更新2

好的我现在正在使用以下代码从IPN模拟器获得响应。我遇到的其他问题是我没有使用我的听众的FQDN并且离开了http：//。

所以现在下一个问题是$res = trim($res);总是空白但我的帖子变量不是。这是因为它是沙盒吗？

<?php 
    $debug            = 1;
    $sandbox          = 1;

    $item_number      = $_POST['item_number'];
    $payment_status   = $_POST['payment_status'];   
    if ($_POST['mc_gross'] != null) {
        $payment_amount   = $_POST['mc_gross'];
    } else {
        $payment_amount   = $_POST['mc_gross1'];
    }
    $payment_currency = $_POST['mc_currency'];
    $txn_id           = $_POST['txn_id'];
    $receiver_email   = $_POST['receiver_email'];
    $payer_email      = $_POST['payer_email'];
    $payment_date     = $_POST['payment_date'];
    $first_name       = $_POST['first_name'];

如果您尝试通过循环在某处记录$res变量，您只需逐行找到响应，例如

$res

这不是解决而是......只是一个想法。 ：）

感谢您的发帖！我有一个类似的问题，IPN被发送，我的服务器使用fsocket验证它，执行代码写入数据库，但PayPal仍然报告了一个＆＃39;交付状态＆＃39; ＆＃39;失败＆＃39;重试几次后，在我的数据库中导致重复。在查看了您的代码后，我发现我正在处理的教程遗漏了这一行，导致PayPal的请求超时而不是显示200：

    $header .= "Connection: close\r\n";

答案 2 :(得分：0)

我遇到了同样的问题，沙箱返回一个空结果。我的代码类似于Tsukasa提供的Update 2.

我不得不将sandbox.paypal.com更改为ipnbp.sandbox.paypal.com，并在其前面加上ssl。 fsocket调用看起来像：

wget --no check certificate --user=my username --password=my password URL
