PayPal IPN不再工作了
[英]PayPal IPN not working anymore
问题描述
Since yesterday the PayPal IPN was working fine, but today I can't receive any IPNs. 
从昨天起，PayPal IPN工作正常，但今天我无法接收任何IPN。 I checked the MySQL, checkt the IPN Adresse and everything is fine. 我检查了MySQL，检查了IPN Adresse，一切都很好。 I was thinking PayPal did some changes on their IPN Server, that woman on the Phone told me no. 我以为PayPal在他们的IPN服务器上做了一些改变，电话里的女人告诉我没有。 Kind of weird. 有点奇怪。
So could someone check the ipn.php & the add.php? 那么有人可以检查ipn.php和add.php吗？

I had the same problem. 我有同样的问题。 They started adding "\\r\\n" to the end of the response so I was comparing "VERIFIED" to "VERIFIED\\r\\n" and it was failing. 他们开始在响应结束时添加“\\ r \\ n”，因此我将“已验证”与“已验证\\ r \\ n”进行比较，但失败了。 You can do: 你可以做：
trim($res)
before testing for VERIFIED, or you can use strpos instead of strcmp : 在测试VERIFIED之前，或者你可以使用strpos而不是strcmp ：
if (strpos($res, "VERIFIED") === 0) (needs ===, not ==) if (strpos($res, "VERIFIED") === 0) （需要===，而不是==）
Finally, they also asked all customers a while back to start adding the Connection header: 最后，他们还要求所有客户回过头来开始添加Connection标头：
$header .= "Connection: close\\r\\n";
