Node.js Laravel通过redis向节点服务器广播事件

我有一个laravel应用程序，我使用事件通知客户端更新。以前我使用pusher来广播这些事件，但我想把它改成redis（或者任何不需要第三方pusher的东西）。我尝试使用predis并发送如下消息：

$redis = Redis::connection();
$redis->publish('message', 'test message');

这确实有效，但我希望广播事件，如：

event（newtestevent（））

，并通过socket.io/redis/etc在节点服务器上接收它们。要执行此操作，我必须更改哪些内容

广播配置：
