Php 为什么notify script向我发送电子邮件，告诉我交易无效？

我已经为paypal的付款做了一个脚本，我通过发送电子邮件检查信息是否正确

notify脚本表示该事务不正确

我想知道为什么。谢谢

你在做很多毫无意义的工作。您所有的fsock/header定义内容都可以被几个

curl

调用所取代，您所有的电子邮件mime垃圾邮件也可以被几行phpmailer/swiftmailer代码所取代。另外，你的身体构造不正确，你在前面加了一个不正确的

&

。@MarcB使用的代码是贝宝提供的默认IPN脚本。它不依赖于给定扩展（如cURL或PHPMailer）的存在。我确信这是非常简单的事情，但法国人正在抛弃我，而且已经很晚了。。对不起，祝你好运。您联系过贝宝支持吗？
