ruby-on-rails – 使用Devise和Omniauth的路由问题

奇怪的是,Google Apps不会出现此问题. (相同的回调路线).

有任何想法吗？

callback_controller：

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController

  def facebook
    # You need to implement the method below in your model
    @user = User.find_for_facebook_oauth(env["omniauth.auth"],current_user)

    if @user.persisted?
      flash[:notice] = I18n.t "devise.omniauth_callbacks.success",:kind => "Facebook"
      sign_in_and_redirect @user,:event => :authentication
    else
      session["devise.facebook_data"] = env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end

  def google_apps
    @user = User.find_for_google_apps_oauth(env["omniauth.auth"],:kind => "Google Apps"
      sign_in_and_redirect @user,:event => :authentication
    else
      session["devise.google_apps_data"] = env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end

  def passthru
    render :file => "#{Rails.root}/public/404.html",:status => 404,:layout => false
  end

end

routes.rb中：

devise_for :users,:controllers => { :omniauth_callbacks => "users/omniauth_callbacks" } do
  get '/users/auth/:provider' => 'users/omniauth_callbacks#passthru'
end

为什么：provider => “facebook”触发RoutingError,但不是：provider => “GOOGLE_APPS”？
