其实ipn才是推荐使用的，因为它是异步处理的，可以避免因为网络问题带来的交易状态更新失败等状况。

你接收到invalid的Response，官方的检查方法如下:

Check that your are posting your response to the correct URL, which is https://www.sandbox.paypal.com/cgi-bi... or https://www.paypal.com/cgi-bin/webscr... depending on whether you are testing in the Sandbox or you are live, respectively.
Verify that your response contains exactly the same IPN variables and values in the same order, preceded with cmd=_notify-validate.
Ensure that you are encoding your response string and are using the same character encoding as the original message.

突然看到你的response里面，test_ipn=1，意思就是你是用来测试paypal的，可是你的response确是从paypal.com收到的，当然Invalid了。把你的接收地址改成sandbox.paypal.com再试试吧。

IPN并不安全，建议用PDT～
