ruby – 使用Omniauth和Google检测到“CSRF”

我得到这个

OmniAuth::Strategies::OAuth2::Callbackerror at /auth/google/callback
csrf_detected | CSRF detected

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.

解决方法

有同样的问题

(google_oauth2) Callback phase initiated.
(google_oauth2)
Authentication failure! csrf_detected:
OmniAuth::Strategies::OAuth2::Callbackerror,csrf_detected | CSRF
detected

最后一个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

猜测我们必须降级到以前的版本,以保持google_oauth2的工作.
