Ruby on rails 设计+；谷歌认证&x2B；可安装引擎路由错误

我正在构建一个用于身份验证的rails应用程序。这里我使用了rails引擎，它包含了整个身份验证过程，我正在使用googleauth和Desive。 问题：当用户用谷歌点击“登录”时，它会成功重定向gmail登录，成功登录后会重定向到

http://localhost:3000/users/auth/google_oauth2/callback?......

下面是它显示的问题

Routing Error
uninitialized constant OmniauthCallbacksController

my_engine/routes.rb

devise_for :users, :controllers => { :omniauth_callbacks => "omniauth_callbacks" }, 
  :class_name => "MyEngine::User", module: :devise

omniauth\u回调\u控制器.rb

require_dependency "my_engine/application_controller"

module MyEngine
  class OmniauthCallbacksController < Devise::OmniauthCallbacksController   
    def googleoauth2
      .....
    end
  end
end

 def googleoauth2  
  @auth = env[OMNI_AUTH]
  @auth_user = AuthUsers.find_by_email(@auth.info.email)
  unless @auth_user
    flash[:error] = "Sorry, you are not authorized."
    redirect_to "/users/sign_in"
  end
  @signed_up_user = User.find_by_email(@auth.info.email)
  email = @auth.info.email
  unless @signed_up_user
    @user = User.find_for_google_oauth2(request.env[OMNI_AUTH], current_user)
  end
  if @auth_user && @signed_up_user
    @user = User.find_for_google_oauth2(request.env[OMNI_AUTH], current_user)
    sign_in_and_redirect @user, :event => :authentication
  end
end

omniauth\u回调\u控制器.rb

require_dependency "my_engine/application_controller"

  class OmniauthCallbacksController < Devise::OmniauthCallbacksController   
    def googleoauth2

  @auth = env[OMNI_AUTH]

目录结构：：

MyEngine ->app -> controllers -> my_engine -> omniauth_callbacks_controller.rb

---

my_engine/routes.rb中的更改

devise_for :users, :controllers => { :omniauth_callbacks => "omniauth_callbacks" }, 
  :class_name => "MyEngine::User", module: :devise

为：用户、：控制器=>{:omniauth\u回调=>“omniauth\u回调”}设计， ：class_name=>“MyEngine:：User”，模块：：设计

到

为：用户，：控制器=>{:omniauth\u回调=>“我的引擎/omniauth\u回调”}，

---

：class_name=>“MyEngine:：User”，module:：designe

你能发布你点击链接后发生的事情的日志吗？它成功重定向到谷歌登录页面，只有回调阶段产生问题。你能发布回调代码吗，那里肯定有问题。@CaffeineCoder你是在要求谷歌OAuth2采取行动吗？是的，它的控制器代码。
