使用Pusher在Laravel的事件中做出廣播功能
使用Pusher在Laravel中做出訊息廣播的功能。
到Pusher官網建立帳號後，建立一個Channel:
- Cluster選擇
ap3 - Backend選擇
Laravel
建立完成後就到https://dashboard.pusher.com/apps 點擊剛剛建立的Channel，接著點選左邊的Getting Started。
找到STEP 2 的地方，安裝pusher，在你的laravel專案底下執行:
1
| composer require pusher/pusher-php-server
|
接著在你的.env檔案中將PUSHER_APP_ID、PUSHER_APP_KEY、PUSHER_APP_SECRET填入，
PUSHER_APP_CLUSTER填入ap3。
重點是 BROADCAST_DRIVER=pusher。
打開 app/Providers/EventServiceProvider.php，在listen中加入:
1
2
3
| 'App\Events\TestPusher' => [
'App\Listeners\SendMessageNotification',
],
|
打開cmd，在你的laravel專案底下執行:
1
| php artisan event:generate
|
接著打開剛剛建立的事件 app/Events/TestPusher.php ，將內容改為:
1

namespace App\Events;
use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;
class TestPusher implements ShouldBroadcast
{
use Dispatchable, InteractsWithSockets, SerializesModels;
public $message;
public function __construct($message)
{
$this->message = $message;
}
public function broadcastOn()
{
return ['my-channel'];
}
public function broadcastAs()
{
return 'my-event';
}
}

在views底下建立視圖pusher.blade.php，code為pusher Getting Started 的STEP 1。

| <?php
use Illuminate\Support\Facades\Route;
use App\Events\TestPusher;
Route::get('/', function () {
return view('welcome');
});
Route::get('/pusher', function () {
return view('pusher');
});
Route::get('/pusher_test', function () {
event(new TestPusher('hello world'));
});
|
打開兩個分頁 /pusher 和 /pusher_test ，打開pusher_test的同時，pusher顯示了訊息Hello world。
