当我在PayPal IPN模拟器中尝试使用这两个脚本时,两者都报告...
IPN已发送且握手已得到验证。
但是,这两个脚本都不会与PayPal进行通信,并且永远不会到达“If VERIFIED”条件。因此,在这种情况之后还没有后端代码是无关紧要的 - 只是想让听众现在能够工作!
我已经和我的虚拟主机谈过了,他们表示他们禁用了SSLv3,希望导致这个问题。它没有任何区别,两个脚本在返回PayPal的地方仍然失败。我的主机声称这不是“他们”的错,而且这是PayPal的问题。尽管将主持人指向相关SO线程的方向(我不能发布,因为没有声望)。

我希望有人能帮助我解决这个,至少可以确认这是“我的”脚本在故障或服务器有过错,因为我一无所获!!
P.S.我对PHP很陌生。
