Question

即使交易已经过验证和完成，PayPal也会不断向同一交易的 myIPNNotificationURL 发送验证

在我的IPN处理程序URL中，我使用Coldfusion CFHTTP发送回发。

<cfhttp url="https://www.sandbox.paypal.com/cgi-bin/webscr?#loc.parameters#" method="get" resolveURL="false"></cfhttp>

这是我对CFHTTP的转储

我也使用Paypal的（IPN）模拟器，它给了我这个错误信息：IPN传递失败。 HTTP错误代码404：未找到

Answer 1

如果他们向您发送多个请求是myIPNNotificationURL，则表示他们多次为该交易点击该网址。幸运的是，这些交易ID是唯一的。这里的关键是识别你何时复制，以便你可以这样对待它。

您可以编写一个脚本，将这些脚本存储到有状态对象（数据库或应用程序范围）中一段时间，以便您可以识别重复项。

一旦你知道你有一个骗局，你可以忽略它。我不知道他们发送给你的信息是什么或者什么，如果你发布它我可以提供一些示例代码。

很抱歉，问题在于我的框架。

PayPal多次回复我的回发
