Rails设计动作电缆 [英] Rails Devise Action Cable

问题描述

我正在尝试让Action Cable与Devise一起使用。

I'm trying to get Action Cable working with Devise.

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

如果用户登录，我仍然会从 cookies.signed中获得 nil ['user.id']

If an user is logged in I still get nil from cookies.signed['user.id']

推荐答案

更新您的 connection.rb 以及以下内容：

Update your connection.rb with the following:

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.studentid
    end

    protected

    def find_verified_user # this checks whether a user is authenticated with devise
      if verified_user = env['warden'].user
        verified_user
      else
        reject_unauthorized_connection
      end
    end
  end
end
