身份验证失败：Devise + OmniAuth + Facebook

Question

我得到（脸书）身份验证失败！ 错误 - omniauth：（facebook）身份验证失败！ csrf_detected：OmniAuth :: Strategies :: OAuth2 :: CallbackError，csrf_detected | CSRF检测到 会员处理:: OmniauthCallbacksController #dailed as HTML

这是我的应用代码

控制器

class Members::OmniauthCallbacksController < Devise::OmniauthCallbacksController   
    def facebook     
        @user = Member.find_for_facebook_oauth(request.env["omniauth.auth"], current_user)      
        if @user.persisted?       
            sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated
            set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
        else
             session["devise.facebook_data"] = request.env["omniauth.auth"]
            redirect_to new_user_registration_url
        end
    end
end

模型

class Member < ActiveRecord::Base
  devise :omniauthable, :database_authenticatable, :confirmable, :registerable, :recoverable, :rememberable, :trackable, :validatable
  validates :lastName, :presence => true
  def self.find_for_facebook_oauth(auth, signed_in_resource=nil)
    user = Member.where(:provider => auth.provider, :uid => auth.uid).first
    if user
      return user
    else
      registered_user = Member.where(:email => auth.info.email).first
      if registered_user
        return registered_user
      else
        user = Member.create(name:auth.extra.raw_info.name,
                            provider:auth.provider,
                            uid:auth.uid,
                            email:auth.info.email,
                            password:Devise.friendly_token[0,20],
                          )
      end    end
  end

end

路线

TestDevice::Application.routes.draw do
  devise_for :members, :controllers => { :omniauth_callbacks => "members/omniauth_callbacks", :sessions => "members/sessions", :passwords => "members/passwords", :registrations => "members/registrations" }
  root "home#index"

  get "boot/new"
  get "boot/show"

  devise_scope :members do

  end

端

布局

-if member_signed_in?
    %h3.text-center.page-header
        You have succesfully signed in
        =link_to "Sign Out", destroy_member_session_path, :method => :delete, :class => "btn btn-primary"
-else
    %h1.text-center.page-header
        Welcome to rails community
    %div.text-center
        =link_to "Sign In", new_member_session_path, :method => :get, :class => "btn btn-primary"
        |
        =link_to "Sign up", new_member_registration_path, :method => :get, :class => "btn btn-primary"
        |
        =link_to "Sign in with Facebook", member_omniauth_callback_path(:facebook), :class => "btn btn-primary"\

devise.rb文件

   require "omniauth-facebook"
  config.omniauth :facebook, "**********", "****************"

控制台看起来像

Started GET "/members/auth/facebook/callback" for 127.0.0.1 at 2014-02-13 09:53:12 +0500
I, [2014-02-13T09:53:12.166717 #74319]  INFO -- omniauth: (facebook) Callback phase initiated.

Processing by Members::OmniauthCallbacksController#failure as HTML

我不明白这是什么意思？我只有config / initializers / devise.rb文件而不是这个文件config / initializers / omniauth.rb。

您必须确保将Facebook应用设置为公开视图。
