PayPal缺少帖子数据

Question

我正在使用paypal

的常规文件

这是zzz.php

 <?php namespace Listener;
    require('PaypalIPN.php');
    use PaypalIPN;
    $ipn = new PaypalIPN();
    // Use the sandbox endpoint during testing.
    $ipn->useSandbox();
    $verified = $ipn->verifyIPN();
    if ($verified) {
        $response = "verified";
        file_put_contents("test.txt", $response);
        /*
         * Process IPN
         * A list of variables is available here:
         * https://developer.paypal.com/webapps/developer/docs/classic/ipn/integration-guide/IPNandPDTVariables/
         */
    }
    header("HTTP/1.1 200 OK");

这是paypalipn.php(来自它们的常规一个(

我正在收到服务器的错误日志中的消息，该消息说：

我已经尝试了一切，但没有成功，我还读过，这可能是我的服务器不允许发布请求正确，但这是我对此知道的第一个问题，如果是这样，我该如何更改这些文件以允许发布请求？

我也在PayPal社区中开了一个问题...这个问题很常见，但没有人正确回答https://www.paypal-community.com/t5/ipn-pdt/missing-post-data/m-p/1448349#m153

非常感谢@Athrun Zara＆amp;@RTFM。我有解决方案!!!!

如果您发现自己有这个问题，只需检查您的Web服务器，如果他们已经解除了空的邮政请求，那就是阻止整个过程而不是编程问题的原因。问题是PayPal首先检查Adress是否是真实的，您的Web服务器将拒绝。

。

垃圾箱已经完成了10个多小时的工作...好吧，我已经学习了整个过程，并在每个编程网站上都开了一个不存在和不可思议的问题。
