events事件:
<?php

{
/* $this->token = $token;
$this->channel = $channel;*/
$this->id = $id;
$this->userId = $userId;
}
/**
* Get the channels the event should be broadcast on.
*
* @return array
*/
public function broadcastOn()

//return [$this->channel];
//公有
//return new Channel('News');
//私有
return new PrivateChannel('News-'. $this->userId);
}
/**
* Get the name the event should be broadcast on.
*
* @return string
*/
/* public function broadcastAs()
{
//return 'dlogin';
} */
public function broadcastWith()
{
// 返回当前时间
return ['name' => 'asfdfa'];
}
}
路由:
Route::get('/ship', function (Request $request,Schedule $schedule)
{
$id = $request->input('id');
event(new News($id)); // 触发事件
return Response::make('Order Shipped!');
});bootstrap.js
import Echo from 'laravel-echo'
window.Echo = new Echo({
broadcaster: 'socket.io',
host: 'http://localhost:6001'
});
界面:
<!-- 文件保存于 resources/views/layouts/child.blade.php -->
<html>
<head>
<meta name="csrf-token" content="{{ csrf_token() }}">

<script src="http://localhost:6001/socket.io/socket.io.js"></script>
<body>
<div id='app'></div>
<div>sdfsf</div>
<script src="{{asset('/js/app.js') }}"></script>
</body>
<script>
//console.log(Echo);
//公有
//Echo.channel('News')
//私有
Echo.private('News')
.listen('News', (e) => {
// 如果有广播过来你可以进行逻辑操作，比如给用户一个通知
console.log(e.name)
});
