我是Rails的新手,正在安装我的第一个集成了Facebook登录/注册的应用程序.我关注了Ryan Bates在这里发布的RailsCast视频： https://stackoverflow.com/a/4954443/1302333.

我按照他的教程来整合Twitter,这有用,但我遇到了Facebook的问题.当我访问http：// localhost：3000 / auth / facebook时,我收到此错误：

和authentications_controller.rb文件：

class AuthenticationsController < ApplicationController
  def index
    @authentications = current_user.authentications if current_user
  end

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

解决方法

您正在使用旧教程版本.

如果您使用的是2.0或更高版本,则步骤为：

config / initializers / devise.rb中的1o

require "omniauth-facebook"
config.omniauth :facebook,"YOUR_APP_ID","YOUR_APP_SECRET",:strategy_class => OmniAuth::Strategies::Facebook

2o你必须安装这个宝石：

gem 'omniauth'
gem 'omniauth-facebook'
gem 'oauth2'

你在user.rb模型添加模块3o：omniauthable ……

class User
 # Include default devise modules. Others available are:
 # :token_authenticatable,:encryptable,:confirmable,:lockable,:timeoutable,:omniauthable and :invitable
  devise :database_authenticatable,:registerable,:recoverable,:rememberable,:trackable,:validatable,:omniauthable
end

在您的routes.rb中4o

devise_for :users,:controllers => { :omniauth_callbacks => "users/omniauth_callbacks",:registrations => "registrations" } do

5o在您的控制器文件夹中创建文件夹用户,并且必须在app / controllers / users / omniauth_callbacks_controller.rb中创建文件之后

在这个omniauth_callbacks_controller.rb中

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook

     # with this code you can see the data sent by facebook
     omniauth = request.env["omniauth.auth"] 

    @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 new_user_registration_url
    end
   end
end

6o在你的user.rb模型中添加到最后这两种方法：

def self.find_for_facebook_oauth(auth,signed_in_resource=nil)
  user = User.where(:provider => auth.provider,:uid => auth.uid).first
  unless user
    user = User.create(name:auth.extra.raw_info.name,provider:auth.provider,uid:auth.uid,email:auth.info.email,password:Devise.friendly_token[0,20]
                         )
  end
  user
end

def self.new_with_session(params,session)
    super.tap do |user|
      if data = session["devise.facebook_data"] && session["devise.facebook_data"]["extra"]["user_hash"]
        user.email = data["email"]
      end
    end
  end

7o最后你必须添加一个链接来连接facebook：

在您的devise / registrations / new.html.erb中,您必须添加：

<%= link_to "Sign in with Facebook",user_omniauth_authorize_path(:facebook) %>

就这样.我希望它会有所帮助！问候
