本文并没有kafka的安装教程,本文是针对已经安装kafka及其设置好kafka的php拓展而且利用laravel框架举办开拓项目,设置一个可供laravel框架利用的出产及消费者类.
以下代码修改自本站的YII框架关于kafka类的代码,颠末测试利用在本人的项目中,可正常运行,larvael版本:5.6 代码安排larvael框架位置:app/Tools/Kafka.php
<?php namespace App\Tools; use Illuminate\Config\Repository; use Illuminate\Support\Facades\DB; use Monolog\Logger; use Monolog\Handler\StreamHandler; use Illuminate\Http\Request; class Kafka { public $broker_list = '127.0.0.1';//设置kafka，可以用逗号离隔多个kafka public $topic = 'test';//管道名称 public $partition = 0; protected $producer = null; protected $consumer = null; public function __construct() { if (empty($this->broker_list)) { throw new InvalidConfigException("broker not config"); } $rk = new \RdKafka\Producer(); if (empty($rk)) { throw new InvalidConfigException("producer error"); } $rk->setLogLevel(LOG_DEBUG); if (!$rk->addBrokers($this->broker_list)) { throw new InvalidConfigException("producer error"); } $this->producer = $rk; } /** * 出产者 * @param array $messages * @return mixed */ public function send($messages = [],$topic) { $topic = $this->producer->newTopic($topic); return $topic->produce(RD_KAFKA_PARTITION_UA, $this->partition, json_encode($messages)); } /** * 消费者 */ public function consumer($object, $callback){ $conf = new \RdKafka\Conf(); $conf->set('group.id', 0); $conf->set('metadata.broker.list', $this->broker_list); $topicConf = new \RdKafka\TopicConf(); $topicConf->set('auto.offset.reset', 'smallest'); $conf->setDefaultTopicConf($topicConf); $consumer = new \RdKafka\KafkaConsumer($conf); $consumer->subscribe([$this->topic]); echo "waiting for messages.....\n"; while(true) { $message = $consumer->consume(120*1000); switch ($message->err) { case RD_KAFKA_RESP_ERR_NO_ERROR: echo "message payload...."; $object->$callback($message->payload); break; } sleep(1); } } } ?>
在节制器中如何利用:
首先再头部导入这个类:use App\Tools\Kafka;
下面是利用出产者实例:
public function test(){ $topic = 'tool';//输入利用管道名称 $data['shop_id'] = 58; $data['bar_code']=586; $data['goods_num'] = 1; $data['goods_unit'] = '个'; $Kafka = new Kafka(); $Error_Msg = $Kafka->send($data,$topic);//传入数组会自动转换json var_dump($Error_Msg); }
下面是消费者实例,消费者我这里利用了的是php剧本举办的操纵:
<?php $conf = new RdKafka\Conf(); $conf->set('group.id', 'myConsumerGroup'); $rk = new RdKafka\Consumer($conf); $rk->addBrokers("localhost:9092"); $topicConf = new RdKafka\TopicConf(); $topicConf->set('auto.commit.interval.ms', 100); $topicConf->set('offset.store.method', 'file'); $topicConf->set('offset.store.path', sys_get_temp_dir()); $topicConf->set('auto.offset.reset', 'smallest'); $topic = $rk->newTopic("tool", $topicConf);//读取的管道 // Start consuming partition 0 $topic->consumeStart(0, RD_KAFKA_OFFSET_STORED); while (true) { $message = $topic->consume(0, 120*10000); switch ($message->err) { case RD_KAFKA_RESP_ERR_NO_ERROR: //没有错误打印信息 $message = json_decode(json_encode($message),true); $data = json_decode($message['payload'],true); var_dump($data); break; case RD_KAFKA_RESP_ERR__PARTITION_EOF: echo "期待吸收信息\n"; break; case RD_KAFKA_RESP_ERR__TIMED_OUT: echo "超时\n"; break; default: throw new \Exception($message->errstr(), $message->err); break; } sleep(1); } ?>
