"CSRF检测到"与Omniauth和Google合作

Question

我得到了这个

OmniAuth :: Strategies :: OAuth2 ::/auth/google/callback中的CallbackError csrf_detected | CSRF检测到

我的代码:

require 'sinatra'
require "sinatra/json"
require "sinatra/config_file"
require 'omniauth-oauth2'
require 'omniauth-google-oauth2'

use Rack::Logger

config_file "config/app_config.yml"
use Rack::Session::Cookie, secret: '5fb7w345y3489f523y4h'

configure do
  enable :sessions
end

use OmniAuth::Builder do
  provider :google_oauth2, settings.google[:client_id], settings.google[:secret],
    {
      :scope => "userinfo.profile",
      :access_type => "offline",
      :prompt => "select_account consent",
      :name => "google"
    }
end

get '/list' do
  json get_list
end

get '/' do
  %Q|<a href='/auth/google'>Sign in with Google</a>|
end

get '/auth/:name/callback' do
  @auth = request.env['omniauth.auth']
  @auth.inspect
end

我的回调是返回代码和状态.

Answer 1

得到了同样的问题

(google_oauth2)已启动回调阶段.
(google_oauth2)身份验证失败!csrf_detected:OmniAuth :: Strategies :: OAuth2 :: CallbackError,csrf_detected | CSRF检测到

最后一次Omniauth-oauth2更新引入了"state"param有一个必填字段.

有些人建议使用provider_ignores_state:true但这是一个坏主意,因为它引入了csrf缺陷

猜猜我们将不得不降级到以前的版本以保持google_oauth2正常运行.

Answer 2

当定义的域/config/initializer/session_store.rb与google api控制台中定义的origin/redirect_uri不同时,rails会出现此问题.

MyApp::Application.config.session_store :cookie_store, key: '_app_session', domain: 'my_app.com'

删除域params或双方使用相同的域修复了该问题.

如果你正在使用Devise和OmniAuth,你需要跳过额外的omniauth.rb初始化文件,只需在initializers/devise.rb中添加config.provider"KEY","SECRET",然后继续执行.
