php - 如何使用 lumen 广播将消息发布到 redis channel ？

Question

我的 lumen 应用程序中有一个名为“Event1”的事件和一个事件监听器“Event1Listener”。当 event1 被触发时，我需要将自定义消息发布到名为“channel1”的 redis channel 。我该怎么做？

Event1.php

<?php
    namespace App\Events;
    use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
    class Event1 extends Event implements ShouldBroadcast
    {
        /**
        * Create a new event instance.
        * @return void
        */
        public function __construct() {        
        }
        /**
        * Get the channels the event should be broadcast on.
        *
        * @return array
        */
        public function broadcastOn() {
            return ['channel1'];
        }
    }
?>

Event1Listener.php

<?php

    namespace App\Listeners;

    use App\Events\Event1;
    use Illuminate\Queue\InteractsWithQueue;
    use Illuminate\Contracts\Queue\ShouldQueue;

    class Event1Listener  {
        /**
        * Create the event listener.
        *
        * @return void
        */
        public function __construct(){
        }
        /**
        * Handle the event.
        *
        * @param  Event1  $event
        * @return void
        */
        public function handle(Event1 $event) {
            echo "What should I add here?";
        }
    }
?>

假设您已经配置了 Redis 如果没有，请查看 laravel documentation和 lumen documentation

要将消息发布到 channel ，您可以使用命令

public function handle(Event1 $event) {
    Redis::publish('channel1', json_encode(['foo' => 'bar']));
}
