生产者

namespace App\Producer;

use EasySwoole\Component\Process\AbstractProcess;
use EasySwoole\Kafka\Config\ProducerConfig;
use EasySwoole\Kafka\Kafka;

class Process extends AbstractProcess
{
    protected function run($arg)
    {

            $config->setRequiredAck(1);

            $kafka = new kafka($config);
            $result = $kafka->producer()->send([
                [
                    'topic' => 'test',
                    'value' => 'message--',
                    'key'   => 'key--',

            var_dump($result);
            var_dump('ok');
        });
    }
}

消费者

namespace App\Consumer;

use EasySwoole\Component\Process\AbstractProcess;
use EasySwoole\Kafka\Config\ConsumerConfig;
use EasySwoole\Kafka\Kafka;

class Process extends AbstractProcess
{
    protected function run($arg)

        go(function () {
            $config = new ConsumerConfig();
            $config->setRefreshIntervalMs(1000);
            $config->setMetadataBrokerList('127.0.0.1:9092,127.0.0.1:9093');
            $config->setBrokerVersion('0.9.0');
            $config->setGroupId('test');

            $config->setTopics(['test']);
            $config->setOffsetReset('earliest');

            $kafka = new Kafka($config);
            // 设置消费回调
            $func = function ($topic, $partition, $message) {
                var_dump($topic);
                var_dump($partition);
                var_dump($message);
            };
            $kafka->consumer()->subscribe($func);
        });
    }
}
