Ruby on rails 设计+；Heroku上的omniauth路由问题

我在这件事上花了好几个小时。。。我有一个Desive和omniauth设置，允许用户使用他们的Facebook帐户登录。我正在使用以下gem版本：

Installing devise (1.4.7)
Installing oauth2 (0.4.1)
Installing oa-oauth (0.2.6)
Installing omniauth (0.2.6)

在我的Desive初始值设定项中包含应用程序id和密码：

config.omniauth :facebook, 'app_id', 'app_secret',
          {:scope => 'email, offline_access', :client_options => {:ssl => {:verify => false}}}

虽然我也尝试过，但运气不好：

config.omniauth :facebook, 'app_id', 'app_secret',
          # {:scope => 'email, offline_access', :client_options => {:ssl => {:ca_file => '/usr/lib/ssl/certs/ca-certificates.crt'}}}

get '/users/auth/:provider' => 'user/authentications#passthru'

我的用户模型中有：omniauthable指令，我在routes文件中定义了自己的回调控制器：

devise_for :users, :controllers => { :omniauth_callbacks => 'user/authentications', :registrations => 'registrations' }

root :to => 'pages#home'

我还尝试将此添加到routes文件，但没有成功：

config.omniauth :facebook, 'app_id', 'app_secret',
          # {:scope => 'email, offline_access', :client_options => {:ssl => {:ca_file => '/usr/lib/ssl/certs/ca-certificates.crt'}}}

get '/users/auth/:provider' => 'user/authentications#passthru'

这是我的身份验证控制器：

class AuthenticationsController < Devise::OmniauthCallbacksController
  def index
    @authentications = current_user.authentications if current_user
  end

  def facebook
    omniauth = request.env["omniauth.auth"]
    authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid'])
    if authentication
      flash[:notice] = "Signed in successfully."
      sign_in_and_redirect(:user, authentication.user)
    elsif current_user
      current_user.authentications.create!(:provider => omniauth['provider'], :uid => omniauth['uid'])
      flash[:notice] = "Authentication successful."
      redirect_to authentications_url
    else
      user = User.new
      user.apply_omniauth(omniauth)
      if user.save
        flash[:notice] = "Signed in successfully."
        sign_in_and_redirect(:user, user)
      else
        session[:omniauth] = omniauth.except('extra')
        redirect_to new_user_registration_url
      end
    end
  end

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

  def destroy
    @authentication = current_user.authentications.find(params[:id])
    @authentication.destroy
    flash[:notice] = "Successfully destroyed authentication."
    redirect_to authentications_url
  end
end

我试图重置我的数据库，但也没用

以下是我从Heroku出发的路线：

        new_user_session GET    /users/sign_in(.:format)               {:action=
>"new", :controller=>"devise/sessions"}
            user_session POST   /users/sign_in(.:format)               {:action=
>"create", :controller=>"devise/sessions"}
    destroy_user_session GET    /users/sign_out(.:format)              {:action=
>"destroy", :controller=>"devise/sessions"}
  user_omniauth_callback        /users/auth/:action/callback(.:format) {:action=
>/facebook/, :controller=>"user/authentications"}
           user_password POST   /users/password(.:format)              {:action=
>"create", :controller=>"devise/passwords"}
       new_user_password GET    /users/password/new(.:format)          {:action=
>"new", :controller=>"devise/passwords"}
      edit_user_password GET    /users/password/edit(.:format)         {:action=
>"edit", :controller=>"devise/passwords"}
                         PUT    /users/password(.:format)              {:action=
>"update", :controller=>"devise/passwords"}
cancel_user_registration GET    /users/cancel(.:format)                {:action=
>"cancel", :controller=>"registrations"}
       user_registration POST   /users(.:format)                       {:action=
>"create", :controller=>"registrations"}
   new_user_registration GET    /users/sign_up(.:format)               {:action=
>"new", :controller=>"registrations"}
  edit_user_registration GET    /users/edit(.:format)                  {:action=
>"edit", :controller=>"registrations"}
                         PUT    /users(.:format)                       {:action=
>"update", :controller=>"registrations"}
                         DELETE /users(.:format)                       {:action=
>"destroy", :controller=>"registrations"}
                    root        /                                      {:control
ler=>"pages", :action=>"home"}

非常感谢您的帮助。如果您需要任何其他信息，请告诉我。我知道它很小，但我觉得我已经尝试了上千种不同的方法，但都没有效果。

我认为，您的authenicatine行应该使用find_或create

authentication = Authentication.find_or_create_by_provider_and_uid(omniauth['provider'], omniauth['uid']) 身份验证=身份验证。通过提供程序和uid查找或创建（omniauth['provider']，omniauth['uid']） 最后我换了衣服

devise_for :users, :controllers => { :omniauth_callbacks => 'user/authentications', :registrations => 'registrations' }

到

它开始在本地和Heroku上工作。

您的“passthru”操作不是在呈现404.html吗。如果您正在执行get'/users/auth/：provider'=>“user/authentications#passthru”，则它是，但我当前未使用它。我在查找后检查身份验证是否为零。如果它是nil，则在我的控制器中该方法的下一步创建它。
