我是 Rails 和 Microsoft Graph/Omniauth 等的完全新手，并且有点卡住了。
我已经按照Microsoft Graph 教程逐字逐句地遵循了https://docs.microsoft.com/en-us/graph/tutorials/ruby Build Ruby on Rails 应用程序。在添加 Azure AD 身份验证实现登录，我开始启动服务器应该重定向到https://login.microsoftonline.com我得到：
OmniAuth::AuthenticityError Forbidden.
当显示上述错误时，我没有被定向到登录我的 URL 是：http://localhost:3000/auth/microsoft_graph_auth。
我正在运行 Ruby 2.7。而不是 2.6.6（如文档中所述）。
有没有人有任何指示和/或建议？
提前致谢！
