这个类位于我的应用中，但它源自 [Setup DiscourseConnect - Official Single-Sign-On for Discourse (sso)](https://meta.discourse.org/t/discourseconnect-official-single-sign-on-for-discourse-sso/13045) 的官方代码，我将其集成到应用中以管理单点登录（SSO）。

同时也参考了 [https://stackoverflow.com/questions/25478510/incorporating-discourse-sso-with-existing-rails-site-with-devise。](https://stackoverflow.com/questions/25478510/incorporating-discourse-sso-with-existing-rails-site-with-devise%E3%80%82)
