env ['warden']不能使用Rails 5

Question

按照本指南使用Websockets創建聊天功能。 https://www.sitepoint.com/rails-and-actioncable-adding-advanced-features/

我堅持一個問題，即env['warden'].user甚至在用標準設計窗體登錄到應用程序時也沒有任何修復。

如果我用另一種方法（也就是現在評論） - 它返回錯誤的用戶

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

我找到解決方案這篇文章 https://rubytutorial.io/actioncable-devise-authentication/

林不知道它是如何工作的，但它完成了交易。它將如何幫助有類似問題的人。

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 

而且我還創建/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, auth, opts| 
    scope = opts[:scope] 
    auth.cookies.signed["#{scope}.id"] = nil 
    auth.cookies.signed["#{scope}.expires_at"] = nil 
end
