laravel 5.5中广播事件之pusher使用

• 首先注册一个Pusher账号,登陆后台创建app获取相关key

　

• laravel中配置Pusher

  • 导入Pusher SDK

composer require pusher/pusher-php-server　　

• • 配置Pusher证书，config/broadcasting.php   注意修改默认项！

<?php

return [
    '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'),
                'encrypted' => true,
            ],
        ],
        'redis' => [
            'driver' => 'redis',
            'connection' => 'default',
        ],
        'log' => [
            'driver' => 'log',
        ],
        'null' => [
            'driver' => 'null',
        ],
    ],
];

• • 建立事件并配置，Events/TestEvent.php  如果该事件没有继承 Illuminate\Contracts\Broadcasting\ShouldBroadcast接口，那么触发使事件将不会发送事件至 pusher 服务器上

php artisan make:event TestEvent

<?php

namespace App\Events;

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

class TestEvent implements ShouldBroadcast　
{
    use Dispatchable, InteractsWithSockets, SerializesModels;
    public $content;

    /**
     * Create a new event instance.
     * @return void
     */
    public function __construct($content)
    {$this->content = $content;
    }

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

    /**
     * 指定广播事件(对应前端的事件)
     * @return string
     */
    public function broadcastAs()
    {
        return 'my-event';
    }

    /**
     * 获取广播数据,默认是广播的public属性的数据
     */
    public function broadcastWith()
    {
        return [
            'content' => $this->content
        ];
    }
}

• • 触发事件

event(new \App\Events\TestEvent('test'));

• 前端代码实现可以在Pusher后台文档中直接copy使用即可
