首先，对ActionCable功能非常陌生。我一直在这里学习教程：https://www.driftingruby.com/episodes/push-notifications-with-actioncable
创建名为web_notifications_channel和web_notifications_channel.rb的通道：

class WebNotificationsChannel < ApplicationCable::Channel
  def subscribed
    stream_from "web_notifications_channel"
  end

  def unsubscribed
    # Any cleanup needed when channel is unsubscribed
  end
end

网络通知通道.js：

import consumer from "./consumer"

consumer.subscriptions.create("WebNotificationsChannel", {
  connected() {
    // Called when the subscription is ready for use on the server
  },

  disconnected() {
    // Called when the subscription has been terminated by the server
  },

  received(data) {
    // Called when there's incoming data on the websocket for this channel
    console.log(`wtf`)
    
  }
});

控制台中未显示任何内容。
已将cable.yml中的适配器设置更改为redis，以便从控制台请求：

development:
  adapter: redis

test:
  adapter: test

production:
  adapter: redis
  url: <%= ENV.fetch("REDIS_URL") { "redis://localhost:6379/1" } %>
  channel_prefix: community_rails_production

正在运行控制台命令：

ActionCable.server.broadcast 'web_notifications_channel', 'You have visited the welcome page.'

我得到的响应如下：

Broadcasting to web_notifications_channel: "You have visited the welcome page."
 => 0

但是我的received方法从来没有被调用过！！我在这里疯了，因为我不明白发生了什么！！我已经检查了一些类似的问题，但没有一个帮助我。
PS：我已经为Redis添加了宝石，并从我的控制台启动了Redis。
