NSQ客戶(hù)端

NSQ 是實(shí)時(shí)的分布式消息處理平臺(tái)，其設(shè)計(jì)的目的是用來(lái)大規(guī)模地處理每天數(shù)以十億計(jì)級(jí)別的消息。 它具有分布式和去中心化拓?fù)浣Y(jié)構(gòu)，該結(jié)構(gòu)具有無(wú)單點(diǎn)故障、故障容錯(cuò)、高可用性以及能夠保證消息的可靠傳遞的特征。

        // 消費(fèi)者
        \EasySwoole\Component\Process\Manager::getInstance()->addProcess(new ConsumerProcess());
    }

生產(chǎn)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(fèi)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(zèng)

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(hào)）
   2. 根目錄下，docker-compose up -d
   3. 訪問(wèn)localhost:4171，可以查看Web版 nsqadmin 狀態(tài)。
