Ruby on rails 发送后，广播消息将不会显示在浏览器控制台中，actioncable和redis development env

我已经在redis cli中为运行服务器的windows安装了redis

C:\program files\redis>redis-cli
127.0.0.1:6379>

开发电缆.yml是

development:
  adapter: redis
  url: redis://127.0.0.1:6379/0

通知频道rb

class NotificationsChannel < ApplicationCable::Channel
  def subscribed
    stream_from "notifications_#{current_user.id}"
  end
end

第页上的notifications.js是

App.notifications = App.cable.subscriptions.create("NotificationsChannel", {
  connected:  function() {
    alert("hello")
  },
  recieved: function(data) {
    console.log(data)
  }
});

在页面加载时弹出警告，说明已连接。在另一个终端运行rails控制台

irb> ActionCable.server.broadcast("notifications_501", body: "hello")

在rails服务器输出中回顾

NotificationsChannel transmitting {"body"=>"hello"} (via streamed from notifications_501)

但是控制台没有显示JSON对象

**编辑**

创建redis server的另一个实例

C:\program files\redis>redi-cli
127.0.0.1:6379>subscribe "notifications_501"
1)"subscribe"
2)"notifications_501"
3)(integer) 1

打开另一个cli

127.0.0.1:6379>publish "notifications_502" "{\"body\":\"hello\"}"

它传输到rails服务器和订阅的redis服务器

NotificationsChannel transmitting {"body"=>"hello"} (via streamed from notifications_501)

将

notifications.js

更改为

notifications.coffee

并使用如下代码

App.notificationss = App.cable.subscriptions.create "NotificationsChannel",
  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) ->
    alert("hello")
  # Called when there's incoming data on the websocket for this channel

不确定普通javascript为什么不起作用。

我认为，在您第一次尝试时，它不起作用的原因可能是命名

接收的
函数时输入了一个错误。您确实收到了
。
有人有什么想法吗？我已经开始工作了，但不得不将我的notifications.js改为coffee。不知道为什么你肯定是对的！我当时试过了，效果很好。它还帮助我解决了另一个问题，同时尝试使其他DOM行为正常工作，但我无法在接收函数中使用coffeescript。。谢谢
