PHP使用RabbitMQ消息隊列

1、安裝amqp拓展 安裝流程

2、下載工具包 php-amqplib 

composer require php-amqplib/php-amqplib

 

3、代碼操作如下

【消費消息】

<?php 
//配置信息 
$conn_args = array( 
    'host' => '127.0.0.1',
    'port' => '5672',  
    'login' => 'zcw',  
    'password' => '123456', 
    'vhost'=>'/' 
);   
$e_name = 'exchange1'; //交換機名 
$q_name = 'queue1'; //隊列名 
$k_route = 'route1'; //路由key 
 
//創建連接和channel 
$conn = new AMQPConnection($conn_args);   
if (!$conn->connect()) {   
    die("Cannot connect to the broker!\n");   
}   
$channel = new AMQPChannel($conn);   
 
//創建交換機    
$ex = new AMQPExchange($channel);   
$ex->setName($e_name); 
$ex->setType(AMQP_EX_TYPE_DIRECT); //direct類型(常用的有fanout、direct、topic、headers)  
$ex->setFlags(AMQP_DURABLE); //持久化 

   
//創建隊列    
$q = new AMQPQueue($channel); 
$q->setName($q_name);   
$q->setFlags(AMQP_DURABLE); //持久化  

$total = $q->declareQueue();//獲取所有的消息數量
 
//綁定交換機與隊列，並指定路由鍵 
$q->bind($e_name, $k_route); 
 
//1、阻塞模式接收消息 
while(True){ 
    $q->consume('processMessage');   
    //$q->consume('processMessage', AMQP_AUTOACK); //自動ACK應答  
} 

//2 非阻塞模式接收消息 可定時調用
//if($total){
//    for($i=0;$i<$total;$i++){
//        $envelope = $q->get();
//        if($envelope){
//             $msg = $envelope->getBody(); 
//             echo $msg."\n"; //處理消息 
//             $q->ack($envelope->getDeliveryTag()); //手動發送ACK應答
//        }
//    }
//}

$conn->disconnect();   
 
/**
 * 消費回調函數
 * 處理消息
 */ 
function processMessage($envelope, $queue) { 
    $msg = $envelope->getBody(); 
    echo $msg."\n"; //處理消息 
    $queue->ack($envelope->getDeliveryTag()); //手動發送ACK應答
}
?>

 

【生產消息】

<?php
//配置信息 
$conn_args = array( 
    'host' => '127.0.0.1',  
    'port' => '5672',  
    'login' => 'zcw',
    'password' => '123456',
    'vhost'=>'/' 
);   
$e_name = 'exchange1'; //交換機名 
//$q_name = 'queue1'; //無需隊列名 
$k_route = 'route1'; //路由key
 
//創建連接和channel 
$conn = new AMQPConnection($conn_args);   
if (!$conn->connect()) {   
    die("Cannot connect to the broker!\n");   
}   
$channel = new AMQPChannel($conn);   
//創建交換機對象    
$ex = new AMQPExchange($channel);   
$ex->setName($e_name);   
//發送消息 
//$channel->startTransaction(); //開始事務  
for($i=0; $i<5; ++$i){
   $ex->publish($message, $k_route)."\n";
}
 
//$channel->commitTransaction(); //提交事務 
 
$conn->disconnect();

?>
