Ruby on Rails Devise Oauth-facebook OmniAuth::Strategies::OAuth2::CallbackError

我使用 facebook 实现 oauth 登录并设计，当从接受应用程序（弹出窗口）返回时，我收到以下错误：

由于“检测到 Csrf”，无法通过 Facebook 验证您的身份。

这是日志：

于 2014-01-23 23:59:58 +0100 开始获取 127.0.0.1 的“/users/auth/facebook/callback” ActiveRecord::SchemaMigration 加载（0.3ms）从“schema_migrations”中选择“schema_migrations”。* (facebook) 回调阶段启动。 （脸书）身份验证失败！ csrf_Detected：OmniAuth::Strategies::OAuth2::CallbackError，csrf_Detected |检测到 CSRF

我的用户模型

class User < ActiveRecord::Base
    devise :token_authenticatable, :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable, :confirmable,
     :omniauthable, :omniauth_providers => [:facebook]
    before_save :ensure_authentication_token

    has_one :user_settings
    has_many :predictions
    has_many :user_leagues
    has_many :leagues, through: :user_leagues # this wasn't working, solution found: http://stackoverflow.com/questions/1781202/could-not-find-the-association-problem-in-rails

    valid_email_regex = /\A[\w+\-.]+@[a-z\d\-]+(\.[a-z]+)*\.[a-z]+\z/i
     validates :email, format: { with: valid_email_regex }

    validates :firstName, :lastName, :username, presence:true
    acts_as_voter

    def self.find_for_facebook_oauth(auth)
      where(auth.slice(:provider, :uid)).first_or_initialize.tap do |user|
        user.provider = auth.provider
        user.uid = auth.uid
        user.email = auth.info.email
        user.password = Devise.friendly_token[0,20]
        user.firstName = auth.info.name   # assuming the user model has a name
        # user.image = auth.info.image # assuming the user model has an image
        user.save!
      end
    end
end

我在 devise.rb 中有我的 facebook id 和我的秘密

  require "omniauth-facebook"
  OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE if Rails.env.development?
  config.omniauth :facebook, ENV["APP_ID"], ENV['FACEBOOK_SECRET']

我正在通过 javascript 进行验证

jQuery ->
  $('body').prepend('<div id="fb-root"></div>')

  $.ajax
    url: "#{window.location.protocol}//connect.facebook.net/en_US/all.js"
    dataType: 'script'
    cache: true

window.fbAsyncInit = ->
  FB.init(appId: '123512341234', cookie: true)

  $('#sign_in').click (e) ->
    e.preventDefault()
    FB.login (response) ->
      #console.log(response)
      window.location = '/users/auth/facebook/callback' if response.authResponse

  $('#sign_out').click (e) ->
    FB.getLoginStatus (response) ->
      FB.logout() if response.authResponse
    true

导轨4.0.0

非常感谢！

我将其添加到我的 app_name/config/initializers/devise.rb 中

{ provider_ignores_state: true }

所以它最终成为

  require "omniauth-facebook"
  config.omniauth :facebook, ENV["FACEBOOK_APP_ID"], ENV['FACEBOOK_SECRET'], provider_ignores_state: true

希望这对其他人有帮助！
