RabbitMQ+PHP 演示实例

新建rabbit_consumer.php作为消费者

<?php
//配置信息
$conn_args = array(
    'host' => '127.0.0.1',
    'port' => '5672',
    'login' => 'admin',
    'password' => 'admin',
    '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
}
?>

 新建rabbit_publisher.php作为生产者

<?php
//配置信息
$conn_args = array(
    'host' => '127.0.0.1',
    'port' => '5672',
    'login' => 'admin',
    'password' => 'admin',
    '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);



//创建交换机对象
$ex = new AMQPExchange($channel);
$ex->setName($e_name);
date_default_timezone_set("Asia/Shanghai");
//发送消息
//$channel->startTransaction(); //开始事务
for($i=0; $i<5; ++$i){
    sleep(1);//休眠1秒
    //消息内容
    $message = "TEST MESSAGE!".date("h:i:sa");
    echo "Send Message:".$ex->publish($message, $k_route)."\n";
}
//$channel->commitTransaction(); //提交事务

$conn->disconnect();
?>

测试一下：

先起一个窗口同样切换到php目录，输入:php rabbit_consumer.php

运行消费者  -> 消费者接收到消息

然后再起一个dos窗口，切换到php根目录，输入以下命令：php rabbit_publisher.php

运行生产者

 这样就模拟了队列对消息的处理，希望我们通过这篇文章对RabbitMQ的认识都能有一定的提升。
