NSQ客戶端

NSQ 是實時的分布式消息處理平臺，其設計的目的是用來大規模地處理每天數以十億計級別的消息。 它具有分布式和去中心化拓撲結構，該結構具有無單點故障、故障容錯、高可用性以及能夠保證消息的可靠傳遞的特征。

基本使用

注冊Nsq服務

namespace EasySwoole\EasySwoole;

use App\Producer\Process as ProducerProcess;
use App\Consumer\Process as ConsumerProcess;
use EasySwoole\EasySwoole\Swoole\EventRegister;
use EasySwoole\EasySwoole\AbstractInterface\Event;
use EasySwoole\Http\Request;
use EasySwoole\Http\Response;

class EasySwooleEvent implements Event
{

    public static function initialize()
    {
        // TODO: Implement initialize() method.
        date_default_timezone_set('Asia/Shanghai');
    }

    public static function mainServerCreate(EventRegister $register)
    {
        // TODO: Implement mainServerCreate() method.
        // 生產者
        \EasySwoole\Component\Process\Manager::getInstance()->addProcess(new ProducerProcess());
        // 消費者
        \EasySwoole\Component\Process\Manager::getInstance()->addProcess(new ConsumerProcess());
    }

}

生產者

namespace App\Producer;

use EasySwoole\Component\Process\AbstractProcess;

class Process extends AbstractProcess
{
    protected function run($arg)
    {
        go(function () {
            $config = new \EasySwoole\Nsq\Config();
            $topic  = "topic.test";
            $nsqlookup = new \EasySwoole\Nsq\Lookup\Nsqlookupd($config->getNsqdUrl());
            $hosts = $nsqlookup->lookupHosts($topic);

            foreach ($hosts as $host) {
                $nsq = new \EasySwoole\Nsq\Nsq();
                for ($i = 0; $i < 10; $i++) {
                    $msg = new \EasySwoole\Nsq\Message\Message();
                    $msg->setPayload("test$i");
                    $nsq->push(
                        new \EasySwoole\Nsq\Connection\Producer($host, $config),
                        $topic,
                        $msg
                    );
                }
            }
        });
    }
}

消費者

namespace App\Consumer;

use EasySwoole\Component\Process\AbstractProcess;

class Process extends AbstractProcess
{
    protected function run($arg)
    {
        go(function () {
            $topic      = "topic.test";
            $config     = new \EasySwoole\Nsq\Config();
            $nsqlookup  = new \EasySwoole\Nsq\Lookup\Nsqlookupd($config->getNsqdUrl());
            $hosts      = $nsqlookup->lookupHosts($topic);
            foreach ($hosts as $host) {
                $nsq = new \EasySwoole\Nsq\Nsq();
                $nsq->subscribe(
                    new \EasySwoole\Nsq\Connection\Consumer($host, $config, $topic, 'test.consuming'),
                    function ($item) {
                        var_dump($item['message']);
                    }
                );
            }
        });
    }
}

附贈

1. Nsq 集群部署 docker-compose.yml 一份，使用方式如下
   1. 保證4150,4151,4160,4161,4171端口未被占用（占用后可以修改compose文件中的端口號）
   2. 根目錄下，docker-compose up -d
   3. 訪問localhost:4171，可以查看Web版 nsqadmin 狀態。
