如何在同一个表单中使用 Paypal IPN 通知和 notify_url？
How to use Paypal IPN notification and notify_url in the same form?
我正在使用这种贝宝表格（付款可以）订阅计划并且没有收到任何 IPN 通知，但是当我使用贝宝生成的标准贝宝表格时，所有带有 IPN 通知的东西都可以。有没有办法通过此表格获得 IPN？谢谢
这是我的表格。如果我从此表单中删除 notify_url，我只能通过 notify_url 或 IPM 获取数据。
PS>正题！有没有办法同时使用 ipn + notify_url？例如?

Example?
简而言之：没有
但是你想要的结果能达到吗？ 是
多年来，这一直困扰着 Paypal，现在仍然如此。
有一种非常流行的方法（对于那些知道的人）使用 php 和 curl 来解决这个问题，由 Codeseekah 分发。 （不附属）
The concept
An single IPN URL is setup for PayPal to notify your application of
payments. The IPN handler code broadcasts PayPal’s payload to other
IPN URLs you may have selectively or in bulk.
- multiple PayPal IPN URLs now possible
- no need to change any IPN code unless it filters requests by IP
- can centralize IP filtering into the broadcast IPN, which means easier to maintain when PayPal’s IP ranges change
- can centralize logging
- can have queuing and rebroadcast if satellites (all your other IPN URLs) are unreachable
代码
此 IPN 广播代码在 PHP 中，但概念与语言无关。简单地移植代码，它会做得同样好，甚至更好。
