php - PayPal IPN 在付款重定向到成功 URL 后不起作用

我在本地主机上工作。我已经在我的网站上成功实现了 Payza 而不是我也已经开始整合 Paypal。我从某个网站下载了一个代码(不记得从哪里下载了)并尝试在收到的本地主机上测试它，然后我可以根据我的要求在我的网站上修改和实现它。该代码似乎适用于所有步骤，而不是接收发送到我的 URL 的 IPN 数据。由于我使用 localhost 进行开发，因此我使用 ngrok 进行测试(在 Internet 上运行我的 localhost)。下面是两个页面。

最佳答案

IPN 不会在本地主机中接收，它只会在域或实时站点中接收。如果你想查看IPN代码，

  1. 登录到sandbox.paypal.com
  2. 去IPN历史，点击任何一个历史，你会得到IPN完整的url。
  3. 使用 postman 向您的本地主机发送请求。现在您可以验证 IPN 响应
