Laravel 6.xでEventを作成してPusherからメッセージ

### event作成
$ php artisan make:event Test
app/Events/Test.php

class Test implements ShouldBroadcast
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public $message;

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

    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    {
        return new Channel('test_channel');
    }

    public function broadcastAs()
    {
        return 'test_event';
    }
}

### config/broadcasting.php

'default' => env('BROADCAST_DRIVER', 'pusher'),
'connections' => [

        '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'),
                'useTLS' => true,
            ],
        ],

### web.php

Route::get('/sent', function(){
	event(new \App\Events\Test('テストメッセージ'));
});

Route::get('receive', function(){
return <<<HTML

<!DOCTYPE html>
<head>
	<title>Pusher Test</title>
	<script src="https://js.pusher.com/3.2/pusher.min.js"></script>
	<script>
		Pusher.logToConsole = true;

		var pusher = new Pusher('******************',{
			cluster : 'ap3',
			forceTLS: true
		});

		var pusherChannel = pusher.subscribe('test_channel');

		pusherChannel.bind('test_event', function(data){
			alert(data.message);
		});
	</script>
</head>
HTML;
});

broadcastdriverが初期値のnullのままだと動かないので注意が必要です。
