swoole如何監(jiān)聽redis數(shù)據(jù)？

Laravel使用swoole監(jiān)聽redis

開始之前，請先確保redis已經(jīng)正確安裝，并正常運行。

Laravel代碼

在App\Events目錄下新建RedisTest事件

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 監(jiān)聽事件代碼

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 登記事件/監(jiān)聽關(guān)系

protected $listen = [

'App\Events\RedisTest' => [

'App\Listeners\RedisTestListener',

],

];

監(jiān)聽命令

App\Console\Commands\RedisSubscribe 代碼如下

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部分代碼完成

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

supervisor 管理進程

在 /etc/supervisor/conf.d 文件夾下新建 echo.conf , 代碼如下

[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，執(zhí)行以下命令重載

supervisorctl reload

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

進入redis 客戶端，發(fā)布一個廣播通知到 msg_0 頻道

publish msg_0 "Hello Bella"

如果 laravel目錄下的 storage\logs\laravel.log 最后的日志中記錄了廣播發(fā)送的通知，則redis監(jiān)聽功能實現(xiàn)

總結(jié)
