php - Paypal IPN php脚本

Question

我刚刚意识到我在 php 中的 paypal ipn 处理程序不再工作(我什么也没改变)，我使用 the sample php script provided by paypal.

我试图通过多次测试来隔离问题，此时我可以说问题不是“已验证”或“无效”，而是来自以下几行:

[...]

fputs ($fp, $header . $req);
    while (!feof($fp))
    {
        $res = fgets ($fp, 1024);
        if (strcmp ($res, "VERIFIED") == 0)
        {
        // check the payment_status is Completed

[...]

有人知道 paypal 是否改变了什么或者为什么它不起作用吗？

谢谢'

ps:如果我把我的代码放在所有 paypal 测试之前(在“if (!$fp)”行之前)，它就可以正常工作

这是我的代码，我注释了“数据库进程”起作用的地方和不起作用的地方。

<?php

// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';

foreach ($_POST as $key => $value)
{
    $value = urlencode(stripslashes($value));
    $req .= "&$key=$value";
}

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

// assign posted variables to local variables
$payment_status = $_POST['payment_status'];


// DATABASE PROCESS WORKS (BEFORE THE PAYPAL TESTS)



if (!$fp)
{
    // HTTP ERROR
}
else
   {

// DATABASE PROCESS WORKS

    fputs ($fp, $header . $req);
    while (!feof($fp))
    {
        $res = fgets ($fp, 1024);
        if (strcmp ($res, "VERIFIED") == 0)
        {
            // check the payment_status is Completed
            // check that txn_id has not been previously processed
            // check that receiver_email is your Primary PayPal email
            // check that payment_amount/payment_currency are correct
            // process payment


// DATABASE PROCESS NOT WORKING

        }
        else if (strcmp ($res, "INVALID") == 0)
        {
            // log for manual investigation

// DATABASE PROCESS NOT WORKING
        }
    }
fclose ($fp);
}

?>

尝试在 x.xom 上使用更新后的脚本 https://www.x.com/instant-payment-notification-4

它使用 CURL 而不是 fsock
