Php Codeigniter Paypal IPN问题-它没有'；付款成功后，请不要应用任何设置

我已经成功地实现了Ran的Paypal库，我正在使用下面的Paypal IPN控制器。就我用Paypal sandbox测试而言，它工作正常。付款后，我点击返回商户，成功代码正确显示。只是IPN不想发送任何电子邮件，所以我可以验证它是否100%有效。IPN电子邮件发送功能是否存在任何可能导致此行为的问题

谢谢

IPN的发送与按下“后退”按钮无关。据我所知，您的日志是否显示IPN已发送？请记住，您还需要允许paypal帐户使用IPN。我正在使用paypal沙箱，并使用进行测试demo@demo.com贝宝帐户作为商家。我不拥有它。我是否也必须在Paypal沙箱中创建商户帐户？我只有一个做假货的测试demo@demo.comI很久没有和paypal打过交道了，但我记得我有一个注册为开发者的选项——你可以创建自己的
假
商户帐户和买家帐户。在商户账户本身就是你设置IPN url的地方，我的话有点言过其实，因为已经有一段时间了：）我就是这么做的。并对其进行了全面测试。Paypal根本不发送IPN通知。我检查了商户帐户的IPN历史记录，没有发送IPN。可能是什么原因造成的？我想最后一件事，对不起，我帮不了你什么忙，就是确保你在商户账户中激活了IPN选项，因为我猜整个交易都可以正常进行，但它不会通知你。
