我已经按照this link中的指南进行操作,并最终获得了以下日志消息:

我已经在线搜索了,所有解决方案都建议检查各种文件中的拼写。我将它们包括在下面。

Google控制台
我已使用以下授权重定向URL设置了我的Google控制台:
http://localhost:3000/users/auth/google_oauth2/callback
铁路路线
当我做rails routes
时,我有:
user_google_oauth2_omniauth_authorize GET|POST /users/auth/google_oauth2(.:format) users/omniauth_callbacks#passthru
user_google_oauth2_omniauth_callback GET|POST /users/auth/google_oauth2/callback(.:format) users/omniauth_callbacks#google_oauth2
非常感谢您提供任何帮助,以了解为什么此方法不起作用。
答案 0 :(得分:1)
/app/controllers/users/omniauth_callbacks_controllers.rb
这是不正确的。您的控制器名称中还有一个s
。这就是Rails无法找到类的原因。您应该将控制器名称重命名为omniauth_callbacks_controller.rb
。
