我们正在使用PayPal AdaptivePayments SDK一段时间，
现在，与之前相同的网址会在50％的时间内通过302临时重定向将客户重定向到paypal主页。

我们也有同样的问题，但能够通过做一些小改动来解决它。
您需要更改重定向网址：
从此： https://www.paypal.com/webscr&cmd=_ap-payment&paykey=XXXXXXXXXX
要 https://www.paypal.com/webscr?cmd=_ap-payment&paykey=XXXXXXXXXX
请注意'webscr'之后的“？”。

自2017年1月13日星期五以来，我们遇到了完全相同的问题。它似乎主要发生在第一次付款重定向请求中。如果您从Paypal主屏幕导航回来，使用浏览器的后退按钮并再次使用新令牌发布，则可以正常工作。
任何知道解决方案的人都会有很大的帮助！
