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

<?phpnamespace 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

<?phpnamespace 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

<?phpnamespace 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:workdirectory=/home/bella/Downloads/lnmp/echo1.0/echouser=bellaautorestart=trueredirect_stderr=truestdout_logfile=/home/bella/Downloads/lnmp/echo1.0/echo/storage/logs/queue.logloglevel=info[program:echo-redis]command=php artisan redis:subscribedirectory=/home/bella/Downloads/lnmp/echo1.0/echouser=bellaautorestart=trueredirect_stderr=truestdout_logfile=/home/bella/Downloads/lnmp/echo1.0/echo/storage/logs/redis.logloglevel=info

完成后，执行以下命令重载

supervisorctl reload

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

进入redis 客户端，发布一个广播通知到 msg_0 频道

publish msg_0 "Hello Bella"

如果 laravel目录下的 storage\logs\laravel.log 最后的日志中记录了广播发送的通知，则redis监听功能实现
