你得到的错误是什么?你在做什么伐木?你有没有试过/想过添加尝试/捕获?制作一个表单,将标准IPN数据提交给脚本并查看显示给您的错误。 – Sugitime 2013-03-15 22:13:20

我正在登录,IPN不是晚上打到我的听众。最后的日志条目是从2013年3月13日起。正如我所说的,这个脚本在几个月里工作得很好...... – baxterxc60 2013-03-15 22:43:24

如果脚本没有改变,那么我们可能无法通过查看代码本身来找到问题。您的脚本正在监听哪个网址?当您从网络浏览器访问此网址时,会发生什么情况? – 2013-03-15 22:57:49

我在这里遇到了同样的问题,PayPal IPN Listener won't work anymore,发现此修复程序,可能会对您有所帮助。 在你的IPN监听年底附近,

if (strpos($this->response, "VERIFIED") !== false) { 
     return true; 
    } elseif (strpos($this->response, "INVALID") !== false) { 
     return false; 
    } else { 
     throw new Exception("Unexpected response from PayPal."); 
    } 

变化与 “== 0”(等于零) “==假的!”在中频条件下。这个对我有用! 现在我已经写了我的问答/自我回答,我已经联系起来,并且等待一些比我更有经验的程序员可以确认并解释这个问题(如果我做得对的话)。
