callback - PayPal MECL 重定向失败并返回回调

Question

https://www.x.com/developers/community/blogs/ppmacole/using-callback-api

我正在尝试将 PayPal MECL 与引用上述 url 的即时更新集成。

当我设置带回调的快速结帐时出现问题。结帐后我得到了一个 token 。但是，我使用 token 加载沙箱登录页面构建的 url，如下图所示。

您需要确保您已登录到您的 http://developer.paypal.com另一个选项卡中的帐户，以便在沙盒中测试 Express Checkout。否则，您看到的这个窗口就是您所得到的。
