PHP Paypal“官方”IPN监听器无法正常工作

Question

我是Paypal的新手，我试图用IPN知道交易何时完成。我读过Paypal documentation for IPN，它提供了一些IPN listener code samples。我将PHP示例版本（没有任何更改）上载到我的服务器，并使用IPN模拟器向IPN侦听器生成假IPN消息。我期待IPN侦听器能够成功处理IPN消息，并且IPN模拟器确实返回了以下消息：“发送了IPN并且握手得到了验证”。

但是，由IPN监听器生成的日志文件表明监听器无法正确处理IPN消息。以下是日志文件所说的内容：

为什么IPN侦听器无法正常工作？有关信息，由于我仍处于开发模式，我的网站上仍然没有SSL证书，但apparently SSL certificates are not needed to test the IPN listener。

Answer 1

的IPN代码https://github.com/paypal/ipn-code-samples/blob/master/paypal_ipn.php包含：

if (strcmp ($res, "VERIFIED") == 0) { 

，并在网址收到它是小写。也许这是问题所在。

Answer 2

您发送给PayPal验证的下面的字符串似乎是一些虚拟数据。你能否做一个真正的沙盒支付测试，并将真实的IPN数据发回PayPal再次检查验证结果？
