我正试图让Action Cable与Devise合作.

module ApplicationCable
  class Connection < ActionCable::Connection::Base

    identified_by :current_user

    def connect
      self.current_user = find_verified_user
      logger.add_tags 'ActionCable', current_user.name
    end

    protected

    def find_verified_user
      verified_user = User.find_by(id: cookies.signed['user.id'])
      if verified_user && cookies.signed['user.expires_at'] > Time.now
        verified_user
      else
        reject_unauthorized_connection
      end
    end
  end
end

如果用户已登录,我仍然可以nil从中获取cookies.signed['user.id']
