paypal ipn notify_url 工作正常，但在我设置的 return url 上没有任何显示

Question

我起床了运行我的电子商务网站在服务器上。我使用 Paypal IPN 通知向客户发送有关他们付款的通知。我目前正在使用 Paypal 沙箱进行测试。

我继续结帐 => 贝宝开发者帐户 => 付款 => 我在我的贝宝帐户中收到消息，因为 ipn 请求已发送，但我没有在我的订单中获得 ipn 请求的值 table 在数据库中。这可能是什么原因？

我已经按照下面的屏幕截图设置了我的 IPN 详细信息。和我还有我的 Paypal 开发者帐户的 IPN 历史截图。任何人都可以帮助我并告诉我数据库中的值未更新的原因吗？

以下是我的代码：

请帮我解决这个问题。

Answer 1

IPN 与您的 return URL 无关。如果您在 IPN 被触发到您的 return URL 时添加您期望运行的代码，您将不会得到预期的结果。

要向您的 return URL 获取数据，您需要使用 PDT，它与 IPN 非常相似，但旨在发送至 return URL . IPN 转到您的通知 URL，它不应与您的 return URL.
