PHP+RabbitMQ实现消息队列的完整代码

前言

为什么使用RabbitMq而不是ActiveMq或者RocketMq？

首先，从业务上来讲，我并不要求消息的100%接受率，并且，我需要结合php开发，RabbitMq相较RocketMq，延迟较低(微妙级)。至于ActiveMq，貌似问题较多。RabbitMq对各种语言的支持较好，所以选择RabbitMq。

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

  [
   'host' => '127.0.0.1',
   'port' => '5672',
   'login' => 'guest',
   'password' => 'guest',
   'vhost'=>'/',
  ],
  //交换机
  'exchange'=>'word',
  //路由
  'routes' => [],
 ];

baseMQ.php

 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");
  }
 
  
  public function close()
  {
   $this->AMQPConnection->disconnect();
  }
 
  
  public function channel()
  {
   if(!$this->AMQPChannel) {
    $this->AMQPChannel = new AMQPChannel($this->AMQPConnection);
   }
   return $this->AMQPChannel;
  }
 
  
  public function exchange()
  {
   if(!$this->AMQPExchange) {
    $this->AMQPExchange = new AMQPExchange($this->channel());
    $this->AMQPExchange->setName($this->exchange);
   }
   return $this->AMQPExchange ;
  }
 
  
  public function queue()
  {
   if(!$this->AMQPQueue) {
    $this->AMQPQueue = new AMQPQueue($this->channel());
   }
   return $this->AMQPQueue ;
  }
 
  
  public function envelope()
  {
   if(!$this->AMQPEnvelope) {
    $this->AMQPEnvelope = new AMQPEnvelope();
   }
   return $this->AMQPEnvelope;
  }
 }

ProductMQ.php

 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

 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()) ;
 }
