设计的自定义身份验证策略

问题描述

我需要为 https://github.com/plataformatec/devise 编写自定义身份验证策略但似乎没有任何文档.它是怎么做的?

I need to write a custom authentication strategy for https://github.com/plataformatec/devise but there doesn't seem to be any docs. How's it done?

推荐答案

我在 此主题 在设计谷歌组

初始化器/some_initializer.rb:

initializers/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

将以下内容添加到 initializers/devise.rb

add following to initializers/devise.rb

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