IFrame 已正确创建。我在 IFrame 中正确填写了所有内容，结果是:

HTTP Status Code:   500
HTTP Status Message:    The request was unsuccessful due to an unexpected condition encountered by the server.
Error Code :    5006
Error Description : Unable to redirect to Vendor's web site. The Vendor failed to provide a RedirectionURL.

在PHP的demo中是在哪里创建的，这个RedirectionURL是怎么生成的？

Answer 1

当您的 notificationURL 收到来自 Sage Pay 的结果发布时，它需要响应，提供 RedirectURL - 当 Sage Pay 无法到达指定的 notificationURL 或没有返回重定向 URL 时，通常会发生此错误。
