ruby-on-rails - actioncable 无法与生产设备配合使用

Question

我无法使用 docker 在我的 ubuntu 服务器上正确运行 actioncable

这似乎是一种设备验证错误，这是我的终端日志

  There was an exception - NoMethodError(undefined method `user' for nil:NilClass)
        cable_1    | /var/www/acim/public/app/channels/application_cable/connection.rb:17:in `find_verified_user'

这是我的/app/chanels/application_cable/connection.rb

        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
              if (current_user = env['warden'].user)
              #if current_user = User.find_by(id: cookies.signed[:user_id])
                current_user
              else
                reject_unauthorized_connection
              end
            end
          end
        end

我有一个工作设置，使用您评论过的 Warden Cookie 变体以及 Warden_hooks 初始化程序来管理 Cookie 的创建和失效

/app/chanels/application_cable/connection.rb

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

    def connect
      self.current_user = find_verified_user
    end

    private

    def find_verified_user
      if current_user = User.find_by(id: cookies.signed['user_token'])
        current_user.id
      else
        reject_unauthorized_connection
      end
    end
  end
end

/app/config/initializers/warden_hooks.rb

# frozen_string_literal: true

# Set user_token cookie after sign in
Warden::Manager.after_set_user do |user, auth, opts|
  scope = opts[:scope]
  auth.cookies.signed["#{scope}_token"] = user.id
end

# Invalidate user.id cookie on sign out
Warden::Manager.before_logout do |user, auth, opts|
  scope = opts[:scope]
  auth.cookies.signed["#{scope}_token"] = nil
end
