【中文标题】302 url重定向到paypal主页【英文标题】：302 url redirect to paypal home page 【发布时间】：2017-05-29 23:22:40 【问题描述】：我们使用 PayPal AdaptivePayments SDK 已有一段时间了，
现在，50% 的时间使用 302 临时重定向将客户重定向到贝宝主页。
https://www.paypal.com/webscr&cmd=_ap-payment&paykey=XXXXXXXXXX.
代码主要是从贝宝示例中复制过去

【问题讨论】：
【参考方案1】：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上。如果您从 Paypal 主屏幕返回，使用浏览器的后退按钮并使用新令牌再次发布，它可以工作。
任何知道解决方案的人都会有很大帮助！
【讨论】：
这里是来自 paypal 的答案：我们的工程师仍在调查这个问题。我会尽快为您提供更新。谢谢你，祝你有美好的一天！ 您有指向 paypal 上未决问题的链接吗？我们如何跟进？谢谢【参考方案2】：我们也遇到了同样的问题，但通过做一个小改动就能解决。
您需要更改重定向网址：
来自： https://www.paypal.com/webscr&cmd=_ap-payment&paykey=XXXXXXXXXX
收件人： https://www.paypal.com/webscr?cmd=_ap-payment&paykey=XXXXXXXXXX
注意“webscr”后面的“?”。
