可以安装多条 ActionCable 电缆吗? [英] Possible to mount multiple ActionCable cables?

问题描述

是否可以安装多个ActionCablecables相同的 Rails 应用程序?例如:

Is it possible to mount multiple ActionCable cables in the same Rails application? For example as such:

#routes.rb
Rails.application.routes.draw do
  ...
  mount ActionCable.server => '/cable'
  mount ActionCable.server => '/cable2'
end

我知道我可以使用相同的电缆拥有多个频道，但我需要对我的频道使用不同的身份验证方法.根据我的理解，使用同一根电缆是不可能的.

I am aware I can have multiple channels using the same cable, but I require to use different authentication methods for my channels. From my understanding, this is not possible using the same cable.

感谢您的帮助.

推荐答案

如 将 ActionCable 与多种识别方法结合使用，在同一个 Rails 应用中使用不同身份验证方法的一种方法可以是:

As elaborated in Using ActionCable with multiple identification methods, one approach to use different authentication methods in the same Rails app can be:

# app/channels/application_cable/connection.rb

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

    def connect
      self.uuid = SecureRandom.urlsafe_base64
      if env['warden'].user
        self.current_user = find_verified_user
      end
    end

    protected

    def find_verified_user
      return User.find_by(id: cookies.signed['user.id'])
    end
  end
end

经过身份验证的频道:

class AuthenticatedChannel < ApplicationCable::Channel
  def subscribed
    reject and return if current_user.blank?
    stream_for current_user
  end
  ...

匿名频道:

class AnonymousChannel < ApplicationCable::Channel
  def subscribed
    stream_from "channel_#{self.uuid}"
  end
  ...
