Rails omniauth和设计vk的麻烦

Question

我将为我的rails应用程序实现facebook和vkontakte登录（注册），使用facebook一切都可以（登录和注册都可以），就像手册中一样此处

但是vkontakte出了问题，我仍然会得到"空"页面

这是我的代码：

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook
    # You need to implement the method below in your model (e.g. app/models/user.rb)
    @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
  def vkontakte
    @user = User.find_for_vkontakte_oauth(request.env["omniauth.auth"], current_user)
    if @user.persisted?
      flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Vkontakte"
      sign_in_and_redirect @user, :event => :authentication
    else
      session["devise.vkontakte_data"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end
end

型号：

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable,
         :token_authenticatable, :lockable, :timeoutable, :omniauthable #:confirmable, 
  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me, :provider, :uid, :name
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"]["raw_info"]
        user.email = data["email"] if user.email.blank?
      end
      if data = session["devise.vkontakte_data"] && session["devise.vkontakte_data"]["extra"]["raw_info"]
        user.email = data["email"] if user.email.blank?
      end
    end
  end

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

怎么了？

Answer 1

你试过Ryan Bates制作的omniauth railscasts吗？

http://railscasts.com/episodes/360-facebook-authentication-这里是facebook

http://railscasts.com/episodes/235-omniauth-part-1http://railscasts.com/episodes/236-omniauth-part-2

这些用于来自不同社交网络的身份验证。我刚开始使用VK-api，所以如果你在实现这些railscasts时遇到问题，请告诉我。

检查您的服务器主机是否在vk中注册。为了进行开发，您可以编辑/etc/hosts并通过此主机访问您的网站。

示例：站点在myhouse.su 中

/etc/hosts:127.0.1.1 local.inmyhouse.su
