Php PayPal IPN沙盒返回HTTP 302

有人能给我解释一下为什么它总是返回HTTP 302响应代码吗

我已经通过几十个测试付款，我开始拔我的头发在这一点上

编辑。。。第二行应该是：

$data='cmd=\u notify-validate&'。http\u build\u查询（$\u POST）

给我：

请注意，我正在使用ssl://

和端口443。

您应该试试

https://www.sandbox.paypal.com

作为您的端点。我使用它作为我的端点从来没有遇到过问题。

解决方案：忘记在POST请求数据中包含

cmd=\u notify-validate

。

有趣的是，我发现的一切都指向

ssl://

。使用

https://

还触发了一个服务器错误，可能是由于配置错误。@RecoveringNerdaholic确实很奇怪。我建议你改成卷发。
