Question

在我的网站（本地）上，一切运行正常。

但由于某些原因，我在Azure上运行它时遇到错误：here is the link

这是堆栈跟踪：

似乎是我在其中一个dll中需要的Google OAuth2（使用OAuth2实现了与Google云端硬盘的连接，通过控制台应用和我的本地IIS网站对其进行了测试）......

有关如何解决这个问题或指出我正确方向的想法吗？

Answer 1

我通过读取堆栈跟踪的猜测是，Sapico.CMS.Drive.Connector.GetCredentials（）方法试图打开一个端口正在侦听OAuth2回调。这在Azure网站中是不可能的。

尝试查找是否有一种方法让驱动器连接器提供回调URL，而不是网站已在侦听的位置。这将更符合OAuth2协议（http://tools.ietf.org/html/rfc6749）！
