使用Laravel 5.4和pusher向公共频道广播通知

'pusher' => [
    'driver' => 'pusher',
    'key' => env('PUSHER_APP_KEY'),
    'secret' => env('PUSHER_APP_SECRET'),
    'app_id' => env('PUSHER_APP_ID'),
    'options' => [
        'cluster' => env('PUSHER_APP_CLUSTER'),
        'encrypted' => true,
    ],
],

PUSHER_APP_ID=your-pusher-app-id
PUSHER_APP_KEY=your-pusher-app-key
PUSHER_APP_SECRET=your-pusher-app-secret
PUSHER_APP_CLUSTER=your-pusher-app-cluster

namespace App\Events;

use Illuminate\Broadcasting\Channel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Queue\SerializesModels;

class NotificationEvent implements ShouldBroadcast
{
    use SerializesModels;

    public $message;

    public function __construct($message)
    {
        $this->message = $message;
    }

    public function broadcastOn()
    {
        return new Channel('public-channel');
    }
}

event(new NotificationEvent('Hello, world!'));

var pusher = new Pusher('your-pusher-app-key', {
    cluster: 'your-pusher-app-cluster',
    encrypted: true
});

var channel = pusher.subscribe('public-channel');
channel.bind('App\\Events\\NotificationEvent', function(data) {
    alert(data.message);
});
