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
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
