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!
");   
}   
$channel = new AMQPChannel($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."
"; //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."
"; //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!
");   
}   
$channel = new AMQPChannel($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)."
";
}
 
//$channel->commitTransaction(); //提交事务 
 
$conn->disconnect();

?>
