env['warden'] 不适用于 Rails 5 [英] env['warden'] not working with Rails 5

问题描述

我按照本指南使用 Websockets 创建聊天功能.https://www.sitepoint.com/rails-and-actioncable-添加高级功能/

Im following this guide to create Chatting feature with a use of Websockets. https://www.sitepoint.com/rails-and-actioncable-adding-advanced-features/

我遇到了一个问题，即使我使用标准设计表单登录到应用程序，env['warden'].user 也没有重新调整任何内容.

Im stuck with a problem that env['warden'].user is retuning nothing even when Im loggined to the app with standard Devise form.

如果我使用另一种方法(现在已评论) - 它返回错误的用户

And if I use another method (which is commented now) - it return wrong user

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

推荐答案

我在这篇文章中找到了解决方案https://rubytutorial.io/actioncable-devise-authentication/

I found solution on this article https://rubytutorial.io/actioncable-devise-authentication/

我不确定它是如何工作的，但它确实有效.它将如何帮助有类似问题的人.

Im not sure how it works, but it does the deal. How it would help for people with similar problem.

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

And I also created /config/initializers/warden_hooks.rb file

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