PHP+RabbitMQ实现消息队列(代码全篇)

前言先安装PHP对应的RabbitMQ,这里用的是 php_amqp 不同的扩展实现方式会有细微的差异.php扩展地址: http://pecl.php.net/package/amqp具体以官网为准 http://www.rabbitmq.com/getstarted.html 介绍config.php 配置信息BaseMQ.php MQ基类ProductMQ.php 生产者类ConsumerMQ.php 消费者类Consumer2MQ.php 消费者2(可有多个)config.php <?php return [ //配置 ‘host’ => [ ‘host’ => ‘127.0.0.1’, ‘port’ => ‘5672’, ’login’ => ‘guest’, ‘password’ => ‘guest’, ‘vhost’=>’/’, ], //交换机 ’exchange’=>‘word’, //路由 ‘routes’ => [], ];BaseMQ.php <?php /** * Created by PhpStorm. * User: pc * Date: 2018/12/13 * Time: 14:11 / namespace MyObjSummary\rabbitMQ; /* Member * AMQPChannel * AMQPConnection * AMQPEnvelope * AMQPExchange * AMQPQueue * Class BaseMQ * @package MyObjSummary\rabbitMQ / class BaseMQ { /* MQ Channel * @var \AMQPChannel / public $AMQPChannel ; /* MQ Link * @var \AMQPConnection / public $AMQPConnection ; /* MQ Envelope * @var \AMQPEnvelope / public $AMQPEnvelope ; /* MQ Exchange * @var \AMQPExchange / public $AMQPExchange ; /* MQ Queue * @var \AMQPQueue / public $AMQPQueue ; /* conf * @var / public $conf ; /* exchange * @var / public $exchange ; /* link * BaseMQ constructor. * @throws \AMQPConnectionException / public function __construct() { $conf = require ‘config.php’ ; if(!$conf) throw new \AMQPConnectionException(‘config error!’); $this->conf = $conf[‘host’] ; $this->exchange = $conf[’exchange’] ; $this->AMQPConnection = new \AMQPConnection($this->conf); if (!$this->AMQPConnection->connect()) throw new \AMQPConnectionException(“Cannot connect to the broker!\n”); } /* * close link / public function close() { $this->AMQPConnection->disconnect(); } /* Channel * @return \AMQPChannel * @throws \AMQPConnectionException / public function channel() { if(!$this->AMQPChannel) { $this->AMQPChannel = new \AMQPChannel($this->AMQPConnection); } return $this->AMQPChannel; } /* Exchange * @return \AMQPExchange * @throws \AMQPConnectionException * @throws \AMQPExchangeException / public function exchange() { if(!$this->AMQPExchange) { $this->AMQPExchange = new \AMQPExchange($this->channel()); $this->AMQPExchange->setName($this->exchange); } return $this->AMQPExchange ; } /* queue * @return \AMQPQueue * @throws \AMQPConnectionException * @throws \AMQPQueueException / public function queue() { if(!$this->AMQPQueue) { $this->AMQPQueue = new \AMQPQueue($this->channel()); } return $this->AMQPQueue ; } /* Envelope * @return \AMQPEnvelope / public function envelope() { if(!$this->AMQPEnvelope) { $this->AMQPEnvelope = new \AMQPEnvelope(); } return $this->AMQPEnvelope; } }ProductMQ.php <?php //生产者 P namespace MyObjSummary\rabbitMQ; require ‘BaseMQ.php’; class ProductMQ extends BaseMQ { private $routes = [‘hello’,‘word’]; //路由key /* * ProductMQ constructor. * @throws \AMQPConnectionException / public function __construct() { parent::__construct(); } /* 只控制发送成功 不接受消费者是否收到 * @throws \AMQPChannelException * @throws \AMQPConnectionException * @throws \AMQPExchangeException / public function run() { //频道 $channel = $this->channel(); //创建交换机对象 $ex = $this->exchange(); //消息内容 $message = ‘product message ‘.rand(1,99999); //开始事务 $channel->startTransaction(); $sendEd = true ; foreach ($this->routes as $route) { $sendEd = $ex->publish($message, $route) ; echo “Send Message:”.$sendEd."\n"; } if(!$sendEd) { $channel->rollbackTransaction(); } $channel->commitTransaction(); //提交事务 $this->close(); die ; } } try{ (new ProductMQ())->run(); }catch (\Exception $exception){ var_dump($exception->getMessage()) ; }ConsumerMQ.php <?php //消费者 C namespace MyObjSummary\rabbitMQ; require ‘BaseMQ.php’; class ConsumerMQ extends BaseMQ { private $q_name = ‘hello’; //队列名 private $route = ‘hello’; //路由key /* * ConsumerMQ constructor. * @throws \AMQPConnectionException / public function __construct() { parent::__construct(); } /* 接受消息 如果终止 重连时会有消息 * @throws \AMQPChannelException * @throws \AMQPConnectionException * @throws \AMQPExchangeException * @throws \AMQPQueueException */ public function run() { //创建交换机 $ex = $this->exchange(); $ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型 $ex->setFlags(AMQP_DURABLE); //持久化 //echo “Exchange Status:”.$ex->declare()."\n"; //创建队列 $q = $this->queue(); //var_dump($q->declare());exit(); $q->setName($this->q_name); $q->setFlags(AMQP_DURABLE); //持久化 //echo “Message Total:”.$q->declareQueue()."\n"; //绑定交换机与队列，并指定路由键 echo ‘Queue Bind: ‘.$q->bind($this->exchange, $this->route)."\n"; //阻塞模式接收消息 echo “Message:\n”; while(True){ $q->consume(function ($envelope,$queue){ $msg = $envelope->getBody(); echo $msg."\n"; //处理消息 $queue->ack($envelope->getDeliveryTag()); //手动发送ACK应答 }); //$q->consume(‘processMessage’, AMQP_AUTOACK); //自动ACK应答 } $this->close(); } } try{ (new ConsumerMQ)->run(); }catch (\Exception $exception){ var_dump($exception->getMessage()) ; }
