PHP使用RabbitMQ消息队列

1、安装amqp拓展 安装流程

2、下载工具包 php-amqplib 

composer require php-amqplib/php-amqplib

 

3、代码操作如下

【消费消息】

 <?php
 //配置信息
 $conn_args = array(
     'host' => '127.0.0.1',
     'port' => '5672',
     'login' => 'zcw',
     'password' => '123456',
     'vhost'=>'/'
 );
 $e_name = 'exchange1'; //交换机名
 $q_name = 'queue1'; //队列名
 $k_route = 'route1'; //路由key 

 //创建连接和channel
 $conn = new AMQPConnection($conn_args);
 if (!$conn->connect()) {
     die("Cannot connect to the broker!\n");
 }
 $channel = new AMQPChannel($conn);   

 //创建交换机
 $ex = new AMQPExchange($channel);
 $ex->setName($e_name);
 $ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型(常用的有fanout、direct、topic、headers)
 $ex->setFlags(AMQP_DURABLE); //持久化 

 //创建队列
 $q = new AMQPQueue($channel);
 $q->setName($q_name);
 $q->setFlags(AMQP_DURABLE); //持久化  

 $total = $q->declareQueue();//获取所有的消息数量

 //绑定交换机与队列，并指定路由键
 $q->bind($e_name, $k_route); 

 //1、阻塞模式接收消息
 while(True){
     $q->consume('processMessage');
     //$q->consume('processMessage', AMQP_AUTOACK); //自动ACK应答
 } 

 //2 非阻塞模式接收消息 可定时调用
 //if($total){
 //    for($i=0;$i<$total;$i++){
 //        $envelope = $q->get();
 //        if($envelope){
 //             $msg = $envelope->getBody();
 //             echo $msg."\n"; //处理消息
 //             $q->ack($envelope->getDeliveryTag()); //手动发送ACK应答
 //        }
 //    }
 //}

 $conn->disconnect();   

 /**
  * 消费回调函数
  * 处理消息
  */
 function processMessage($envelope, $queue) {
     $msg = $envelope->getBody();
     echo $msg."\n"; //处理消息
     $queue->ack($envelope->getDeliveryTag()); //手动发送ACK应答
 }
 ?>

【生产消息】

 <?php
 //配置信息
 $conn_args = array(
     'host' => '127.0.0.1',
     'port' => '5672',
     'login' => 'zcw',
     'password' => '123456',
     'vhost'=>'/'
 );
 $e_name = 'exchange1'; //交换机名
 //$q_name = 'queue1'; //无需队列名
 $k_route = 'route1'; //路由key

 //创建连接和channel
 $conn = new AMQPConnection($conn_args);
 if (!$conn->connect()) {
     die("Cannot connect to the broker!\n");
 }
 $channel = new AMQPChannel($conn);
 //创建交换机对象
 $ex = new AMQPExchange($channel);
 $ex->setName($e_name);
 //发送消息
 //$channel->startTransaction(); //开始事务
 for($i=0; $i<5; ++$i){
    $ex->publish($message, $k_route)."\n";
 }

 //$channel->commitTransaction(); //提交事务 

 $conn->disconnect();

 ?>
