Question

我有以下问题：我的应用程序作为Facebook应用程序运行，但是在用户第一次接受它的Facebook权限时，它被重定向到正确的URL，但在Facebook（画布）之外。我该如何解决？

以下是我的实际设置：

devise.rb：config.omniauth :facebook, ENV['FACEBOOK_APP_ID'], ENV['FACEBOOK_SECRET'], scope: "email,publish_stream"

应用程序/控制器/ omniauth_callback_controller.rb

class OmniauthCallbacksController < Devise::OmniauthCallbacksController

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


      def facebook

        @user = User.find_for_facebook_oauth(request.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"] = request.env["omniauth.auth"]
          redirect_to root_path
        end
      end

      def after_sign_in_path_for(resource)
        inicio_path
      end
    end

的routes.rb

Pl::Application.routes.draw do



      ActiveAdmin.routes(self)

      mount Resque::Server, :at => "/resque"

      devise_for :admin_users, ActiveAdmin::Devise.config

      devise_for :users, :controllers => { :omniauth_callbacks => "omniauth_callbacks" }

      devise_scope :user do
      get '/users/auth/:provider' => 'users/omniauth_callbacks#passthru'
      end

      match 'states'  => 'game_plays#states'
      match 'cities'  => 'game_plays#cities'
      match 'parties' => 'game_plays#parties'
      match 'prefeito' => 'game_plays#prefeito'
      match 'prefeitos' => 'game_plays#prefeitos'
      match 'vereadores' => 'game_plays#vereadores'
      match 'parties' => 'game_plays#parties'
      match 'qualities' => 'game_plays#qualities'
      match 'start' => 'game_plays#start'
      match 'generated_image' => 'game_plays#generated_image'
      match 'save_game_play' => 'game_plays#save_game_play'
      match 'final' => 'game_plays#final', :as => :final

      match 'inicio'  => 'game_plays#index'  


      root :to => 'game_plays#bem_vindo'

    end

任何sugestions？

这是我几个月前在这个问题上的经验，我希望它有所帮助。

从Facebook的角度来看，这正是它所要做的。它无法识别请求来自何处之间的差异。您必须更改请求中的重定向网址才能保留在iframe中。

我发现这样做的最简单方法是让iframe网址转到my_website.com/fb-app，它会设置一个会话变量，让您知道自己在画布中并确保它们已经通过facebook登录。然后，它将它们重定向到画布站点，站点继续正常，用户从不会注意到任何内容。

def fbapp

  session[:fbapp] = true

  if user_signed_in? == false
    redirect_to user_omniauth_authorize_path(:facebook)
  else
    redirect_to $APP_CANVAS_URL + "?auth_token=" + current_user.authentication_token
  end
end

然后，在Application_controller.rb中，您需要更改重定向路径。这就是我的应用程序中的样子，注意$ APP_CANVAS_URL应该是https://apps.facebook.com/your_app_here

的内容

def after_sign_in_path_for(resource_or_scope)  
  if session[:fbapp] == true
    $APP_CANVAS_URL + "?auth_token=" + current_user.authentication_token
  else
    root_path
  end
end

我怀疑这是最好的方式，但这是我在经历了几个小时的挫折之后为我工作的。我希望它有所帮助。
