用于设计的自定义身份验证策略

我在 this thread 论设计谷歌集团

初始化程序/some_initializer.rb:

Warden::Strategies.add(:custom_strategy_name) do 
  def valid? 
    # code here to check whether to try and authenticate using this strategy; 
    return true/false 
  end 

  def authenticate! 
    # code here for doing authentication; 
    # if successful, call  
    success!(resource) # where resource is the whatever you've authenticated, e.g. user;
    # if fail, call 
    fail!(message) # where message is the failure message 
  end 
end 

在initializers/designe.rb中添加以下内容

  config.warden do |manager| 
     manager.default_strategies.unshift :custom_strategy_name 
  end
