LaravelのBroadcasting EventをPusherでやる

1. PusherでAppを作成

2. Viewを作成

resources/views/welcome.blade.phpを以下の内容に変更

<!DOCTYPE html>
<head>
    <title>Pusher Test</title>
    <script src="https://js.pusher.com/4.1/pusher.min.js"></script>
    <script>

        // Enable pusher logging - don't include this in production
        Pusher.logToConsole = true;

        var pusher = new Pusher('xxxxxx', {
            cluster: 'ap1',
            encrypted: true
        });

        var channel = pusher.subscribe('my-channel');
        channel.bind('my-event', function(data) {
            alert(data.message);
        });
    </script>
</head>

3. ビルトンサーバーで確認

ブラウザのコンソールでログが出る

Pusher : State changed : initialized -> connecting
pusher.min.js:8 Pusher : Connecting : {"transport":"ws","url":"wss://ws-ap1.pusher.com:443/app/xxxxxx?protocol=7&client=js&version=4.1.0&flash=false"}
pusher.min.js:8 Pusher : State changed : connecting -> connected with new socket ID xxxxxxxx
pusher.min.js:8 Pusher : Event sent : {"event":"pusher:subscribe","data":{"channel":"my-channel"}}
pusher.min.js:8 Pusher : Event recd : {"event":"pusher_internal:subscription_succeeded","data":{},"channel":"my-channel"}
pusher.min.js:8 Pusher : No callbacks on my-channel for pusher:subscription_succeeded

4. Pusherのライブラリをインストール

$ composer require pusher/pusher-php-server

5. 設定ファイルを編集

config/broadcasting.phpを編集

'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' => env('PUSHER_APP_ENCRYPTED'),
            ],
        ],

.envを編集

PUSHER_APP_ID=xxxxx
PUSHER_APP_KEY=xxxxx
PUSHER_APP_SECRET=xxxxx
PUSHER_APP_CLUSTER=xxxx
PUSHER_APP_ENCRYPTED=true

6. テストイベントの作成

コマンドからイベントの作成

$ php artisan make:event HelloPusher

イベントでShouldBroadcast Interfaceを継承する
チャンネル名をフロントと合わせる
コンストラクタでメッセージを受け取りセットする

<?php

namespace App\Events;

use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;

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

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Get the channels the event should broadcast on.
     *
     * @return Channel|array
     */
    public function broadcastOn()
    {
        return new Channel('my-channel');
    }

    public function broadcastAs()
    {
        return "my-event";
    }

    public function broadcastWith()
    {
        return [
            'message' => 'Hello Pusher!!'
        ];
    }
}

7. イベントのテスト

web.phpに下記を追記

Route::get('/hello', function(){
    event(new \App\Events\HelloPusher);
});

他のブラウザで/を開いている時に/helloをブラウザで開いてアラートが表示されればOK。
