我按照本指南使用Websockets创建聊天功能.

我遇到了env [‘warden’]的问题.即使我使用标准的Devise表单登录到应用程序,用户也不会重新调整任何内容.

如果我使用另一种方法(现在已经注释) – 它会返回错误的用户

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.email
    end

    protected

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

      if verified_user
        verified_user
      else
        reject_unauthorized_connection
      end
    end

    # def find_verified_user
    #     user_id = request.headers['HTTP_AUTHORIZATION']
    #     if verified_user = User.find_by(user_id)
    #        verified_user
    #     else
    #        reject_unauthorized_connection
    #     end
    # end

  end
end

日志说

Started GET "/cable/" [WebSocket] for 127.0.0.1 at 2017-04-06 17:40:17 +0300
Successfully upgraded to WebSocket (REQUEST_METHOD: GET,HTTP_CONNECTION: Upgrade,HTTP_UPGRADE: websocket)
An unauthorized connection attempt was rejected
Failed to upgrade to WebSocket (REQUEST_METHOD: GET,HTTP_UPGRADE: websocket)

解决方法

我找到了解决这篇文章的方法
https://rubytutorial.io/actioncable-devise-authentication/

我不确定它是如何工作的,但它确实达成了协议.如何对有类似问题的人有所帮助.

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.email
    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

我还创建了/config/initializers/warden_hooks.rb文件

Warden::Manager.after_set_user do |user,auth,opts|
  scope = opts[:scope]
  auth.cookies.signed["#{scope}.id"] = user.id
  auth.cookies.signed["#{scope}.expires_at"] = 60.minutes.from_now
end

Warden::Manager.before_logout do |user,opts|
  scope = opts[:scope]
  auth.cookies.signed["#{scope}.id"] = nil
  auth.cookies.signed["#{scope}.expires_at"] = nil
end
