设计facebook和tweeter，github身份验证发送错误的url

Question

我在config / initializer / devise.rb中使用rails3 rc和ruby 1.9.2rc进行此操作

 config.warden do |manager|
   manager.oauth(:twitter) do |twitter|
    twitter.consumer_secret = "...key....."
    twitter.consumer_key  = ".....app_key......"
    twitter.options :site => 'http://twitter.com'
   end
#  manager.default_strategies(:scope => :user).unshift :twitter_oauth

Warden::OAuth.access_token_user_finder(:twitter) do |access_token|
   user = User.find_by_access_token_and_access_secret(access_token.token, access_token.secret)
   user ||= User.create(:access_token => access_token.token, :secret => access_token.secret)
   end
end

#Warden::OAuth.access_token_user_finder(:twitter) do |access_token| 
#   User.find_or_create_by(:token => access_token.token, :secret => access_token.secret).tap 
# end

  config.oauth :github, '....app_key...', '...secret........',
    :site              => 'https://github.com/',
    :authorize_path    => 'login/oauth/authorize',
    :access_token_path => 'login/oauth/access_token',
    :scope             => %w(user public_repo)

  config.oauth :facebook, '..app_key....',  '..secret........',
    :site              => 'https://graph.facebook.com',
    :authorize_path    => 'login/oauth/authorize',
    :access_token_path => 'login/oauth/access_token'

当我点击以sing_in形式创建的链接时，它会转到face或者twitter或github，但显示未找到消息页面，或者url不存在应该是什么问题
