PHP-PayPal IPN 301永久移动

Question

我之前用过多次用PHP编写的PayPal IPN脚本时遇到了麻烦，但现在却遇到此错误。

[07/31/2018 4:42 PM] - FAIL: IPN Validation Failed.
IPN POST Vars from Paypal:

    IPN Response from Paypal Server:
     HTTP/1.1 301 Moved Permanently
    Server: AkamaiGHost
    Content-Length: 0

我正在使用Micah Carrick制作的脚本。 我的编辑看起来像这样。 paypal.php

              $complete = mysqli_query($db, "UPDATE matches SET status = '2'");

        }
          break;
     }     

    ?>

我已经尝试了在StackOverflow上找到的多个修复程序。 大多数情况下是代码编辑，但我认为这可能不是问题。 我尝试禁用防火墙，以查看是否最终阻止了某些PayPal IP。 但这不是问题。

我也尝试了PHP 5.3.8和PHP 7.2.7，但都没有用，我在Windows 2016 VPS的IIS 10上运行了此脚本。 我还在网站上使用SSL证书，但也尝试过不使用它。

我知道IPN URL是正确的，因为它可以完成我想要的所有事情，除了验证IPN。 但是价格是正确的，付款会通过。 如您所见，查询$ problem甚至执行，但查询$ complete不执行，这就是我所需要的。

有人知道这可能是由什么引起的吗？

2月份的Paypal电子邮件：

Quote：“”我们还鼓励您与网络托管公司，电子商务软件提供商或内部网络程序员/系统管理员联系，以在实施这些更改时获得进一步的帮助（如果需要的话）。此电子邮件中以及在TLS 1.2和HTTP / 1.1升级微型站点可能会有所更改，请监视我们的TLS 1.2和HTTP / 1.1升级微型站点以获取最新信息。以下是一些有关安全更新的关键点，我们将于6月30日后开始实施，2017年，我们强烈建议您与系统兼容，以确保您的业务不中断：•PayPal沙盒或测试环境已升级为仅允许TLS 1.2和HTTP / 1.1连接•所有生产终结点都将更新为接受2017年6月30日之后只能使用TLS 1.2和HTTP / 1.1连接。请注意，如果您尚未对系统进行必要的升级以使其合规，则您的企业将无法接受通过 贝宝（PayPal），直到进行了所需的更改为止。 •可以使用验证端点，可以在https://tlstest.paypal.com上找到该端点，并具有最新的安全标准，因此客户可以快速检查其系统是否准备在2017年6月30日之后接受交易。”

Quote：“到HTTPS的IPN验证回发–在2017年6月30日之前完成需要更新：是”

Micah暂时没有更新他的脚本，但是这个脚本应该对您有用： https : //github.com/xtuc/Paypal-ipn-SDK/blob/master/paypal.class.php
