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（他们常规）

我已经尝试了一切但没有成功，我也认为可能是我的服务器不能正确地发布请求，但这是我知道的第一个问题，如果是这样，我如何更改这些文件以允许发布请求？

我还在paypal社区中提出了一个问题......这个问题很常见，但没有人能正确回答 https://www.paypal-community.com/t5/IPN-PDT/Missing-POST-Data/m-p/1448349#M153

Paypal缺少POST数据
