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
