记得有监狱长

Question

对于我最新的项目,我使用的是https://github.com/hassox/rails_warden.它非常适合我的需求,除了我找不到实现remember_me的好方法.我知道从安全的角度来看,记住这一点是非常困难的,所以我希望有一个能够完成工作的项目.有人见过什么或得到一个好主意？

Answer 1

好的,这就是我如何解决它

 # User model must have remember_token attribute

 # in config.ru
 use Rack::Cookies
 run MyApp

  # in lib/strategies.rb
  Strategies.add(:cookie) do
    def valid?
      env['rack.cookies']['user.remember.token']      
    end

    def authenticate!
      if user = User.find_by_remember_token(cookies['user.remember.token'])
        success! user
      else
        fail! "Could not log in"
      end
    end
  end

  Manager.after_authentication :scope => :user do |user, auth, opts|
    auth.env['rack.cookies']['user.remember.token'] = user.generate_remember_token! # sets its remember_token attribute to some large random value and returns the value
  end

  Manager.before_logout :scoper => :user do |user, auth, opts|
    user.update_attribute :remember_token, nil
  end
