swoole如何监听redis数据？

Laravel使用swoole监听redis

开始之前，请先确保redis已经正确安装，并正常运行。

Laravel代码

在App\Events目录下新建RedisTest事件

<?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 RedisTest {     use Dispatchable, InteractsWithSockets, SerializesModels;     public $message;     /**     * Create a new event instance.     *     * @return void     */     public function __construct($message)     {         $this->message = $message;     }     /**     * Get the channels the event should broadcast on.     *     * @return \Illuminate\Broadcasting\Channel|array     */     public function broadcastOn()     {         return new PrivateChannel('channel-name');     } }

App\Listeners\RedisTestListener 监听事件代码

<?php namespace App\Listeners; use App\Events\RedisTest; use Illuminate\Queue\InteractsWithQueue; use Illuminate\Contracts\Queue\ShouldQueue; use Illuminate\Support\Facades\Log; class RedisTestListener {     /**     * Create the event listener.     *     * @return void     */     public function __construct()     {         //     }     /**     * Handle the event.     *     * @param  RedisTest  $event     * @return void     */     public function handle(RedisTest $event)     {         $message = $event->message;         Log::info('the message received from subscribed redis channel msg_0: '.$message);     } }

App\Providers\EventServiceProvider 登记事件/监听关系

protected $listen = [         'App\Events\RedisTest' => [             'App\Listeners\RedisTestListener',         ],     ];

监听命令

App\Console\Commands\RedisSubscribe 代码如下

<?php namespace App\Console\Commands; use Illuminate\Console\Command; use swoole_redis; use Illuminate\Support\Facades\Event; use App\Events\RedisTest; class RedisSubscribe extends Command {     /**     * The name and signature of the console command.     *     * @var string     */     protected $signature = 'redis:subscribe';     /**     * The console command description.     *     * @var string     */     protected $description = 'deamon process to subscribe redis broadcast';     /**     * Create a new command instance.     *     * @return void     */     public function __construct()     {         parent::__construct();     }     /**     * Execute the console command.     *     * @return mixed     */     public function handle()     {         $client = new swoole_redis;         $client->on('message', function (swoole_redis $client, $result) {             var_dump($result);             static $more = false;             if (!$more and $result[0] == 'message')             {                 echo "trigger Event RedisTest\n";                 Event::fire(new RedisTest($result[2]));             }         });         $client->connect('127.0.0.1', 6379, function (swoole_redis $client, $result) {             echo "connect\n";             $client->subscribe('msg_0');         });     } }

Laravel部分代码完成

==================================

supervisor 管理进程

在 /etc/supervisor/conf.d 文件夹下新建 echo.conf , 代码如下

[group:echos] programs=echo-queue,echo-redis [program:echo-queue] command=php artisan queue:work directory=/home/bella/Downloads/lnmp/echo1.0/echo user=bella autorestart=true redirect_stderr=true stdout_logfile=/home/bella/Downloads/lnmp/echo1.0/echo/storage/logs/queue.log loglevel=info [program:echo-redis] command=php artisan redis:subscribe directory=/home/bella/Downloads/lnmp/echo1.0/echo user=bella autorestart=true redirect_stderr=true stdout_logfile=/home/bella/Downloads/lnmp/echo1.0/echo/storage/logs/redis.log loglevel=info

完成后，执行以下命令重载
