【PHP】实现RabbitMQ消息队列(二)

1、安装拓展及工具包

2、代码实现

a、发布消息

<?php

$_host = '127.0.0.1';//主机
$_port = '5672';//端口
$_login = 'TEST';//账号
$_password = '123123';//密码
$_vhost = 'TEST';//host默认为/

require_once '../../../../vendor/autoload.php';
use PhpAmqpLib\Connection\AMQPStreamConnection;
use PhpAmqpLib\Message\AMQPMessage;

$exchange = 'TEST';//交换机
$connection = new AMQPStreamConnection($_host, $_port, $_login, $_password, $_vhost);
$channel = $connection->channel();
$channel->exchange_declare($exchange, 'direct', true, false, false);

$routerKey = 'lol_status';

//模拟批量发布消息
for ($i = 0; $i < 100; $i++) {
    $arr = [
        'match_id' => $i,
        'status' => rand(0,3),
        'time'=> date('Y-m-d H:i:s')
    ];
    $data = json_encode($arr,JSON_UNESCAPED_UNICODE);
    $msg = new AMQPMessage($data);
    $channel->basic_publish($msg, $exchange, $routerKey);
    echo '发送 '.$routerKey.' 消息: ' . $data . PHP_EOL;
}
$channel->close();
$connection->close();

?>

 

b、消费消息

<?php

$_host = '127.0.0.1';
$_port = '5672';
$_login = 'TEST';
$_password = '123123';
$_vhost = 'TEST';

require_once '../../../../vendor/autoload.php';
use PhpAmqpLib\Connection\AMQPStreamConnection;

$exchange = 'TEST';//交换机名称
$queueName = 'lol';//队列名称
$routerKey = 'lol_status'; //路由key

$connection = new AMQPStreamConnection($_host, $_port, $_login, $_password, $_vhost);
$channel = $connection->channel();
$channel->exchange_declare($exchange, 'direct', true, false, false);
$channel->queue_bind($queueName, $exchange, $routerKey);

//获取消息数量信息
$declare_info = $channel->queue_declare($queueName,true);//$declare_info[1] 消息数量

echo " 等待消息中..." .PHP_EOL;
$callback = function ($msg){
    echo '接收到消息：',$msg->delivery_info['routing_key'], ':', $msg->body, PHP_EOL;
    //$msg->delivery_info['channel']->basic_ack($msg->delivery_info['delivery_tag']);//手动应答
};

//第4个参数  false:手动应答 true:自动应答
$channel->basic_consume($queueName, '', false, true, false, false, $callback);

//阻塞模式
while ($channel->is_consuming()) {
    $channel->wait();
}

$channel->close();
$connection->close();

?>
