装好了amqp后就可以开始编写代码了:
消费者:接收消息
逻辑:
创建连接-->创建channel-->创建交换机-->创建队列-->绑定交换机/队列/路由键-->接收消息
<?php /************************************* * PHP amqp(RabbitMQ) Demo - consumer * Author: Linvo * Date: 2012/7/30 *************************************/ //配置信息 $conn_args = array( 'host' => '192.168.1.93', 'port' => '5672', 'login' => 'guest', 'password' => 'guest', 'vhost'=>'/' ); $e_name = 'e_linvo'; //交换机名 $q_name = 'q_linvo'; //队列名 $k_route = 'key_1'; //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 $ex->setFlags(AMQP_DURABLE); //持久化 echo "Exchange Status:".$ex->declare()."\n"; //创建队列 $q = new AMQPQueue($channel); $q->setName($q_name); $q->setFlags(AMQP_DURABLE); //持久化 echo "Message Total:".$q->declare()."\n"; //绑定交换机与队列,并指定路由键 echo 'Queue Bind: '.$q->bind($e_name, $k_route)."\n"; //阻塞模式接收消息 echo "Message:\n"; while(True){ $q->consume('processMessage'); //$q->consume('processMessage', AMQP_AUTOACK); //自动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 }
生产者:发送消息
逻辑:
创建连接-->创建channel-->创建交换机对象-->发送消息
<?php /************************************* * PHP amqp(RabbitMQ) Demo - publisher * Author: Linvo * Date: 2012/7/30 *************************************/ //配置信息 $conn_args = array( 'host' => '192.168.1.93', 'port' => '5672', 'login' => 'guest', 'password' => 'guest', 'vhost'=>'/' ); $e_name = 'e_linvo'; //交换机名 //$q_name = 'q_linvo'; //无需队列名 $k_route = 'key_1'; //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); //消息内容 $message = "TEST MESSAGE! 测试消息!"; //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){ echo "Send Message:".$ex->publish($message, $k_route)."\n"; } //$channel->commitTransaction(); //提交事务 $conn->disconnect();
queue对象有两个方法可用于取消息:consume和get。
前者是阻塞的,无消息时会被挂起,适合循环中使用;
后者则是非阻塞的,取消息时有则取,无则返回false。

运行消费者:
运行生产者,发消息:
消费者接收到消息:
