php运用PhpAmqpLib操作队列

//安装类库
composer require php-amqplib/php-amqplib

 

//consumer.php消费者代码
require __DIR__ . "/../vendor/autoload.php";

use PhpAmqpLib\Connection\AMQPStreamConnection;

$conf         = [
    'host'  => '127.0.0.1',
    'port'  => 5672,
    'user'  => '',
    'pwd'   => '',
    'vhost' => '/',
];
$exchangeName = '_ex'; //交换机名
$queueName    = '_que'; //队列名称
$routingKey   = '_send'; //路由关键字(也可以省略)

$conn    = new AMQPStreamConnection( //建立生产者与mq之间的连接
    $conf['host'], $conf['port'], $conf['user'], $conf['pwd'], $conf['vhost']
);
$channel = $conn->channel(); //在已连接基础上建立生产者与mq之间的通道
$channel->exchange_declare($exchangeName, 'direct', false, true, false); //声明初始化交换机
$channel->queue_declare($queueName, false, true, false, false); //声明初始化一条队列
$channel->queue_bind($queueName, $exchangeName, $routingKey); //将队列与某个交换机进行绑定，并使用路由关键字
//1:queue 要取得消息的队列名
//2:consumer_tag 消费者标签
//3:no_local false这个功能属于AMQP的标准,但是rabbitMQ并没有做实现.参考
//4:no_ack  false收到消息后,是否不需要回复确认即被认为被消费
//5:exclusive false排他消费者,即这个队列只能由一个消费者消费.适用于任务不允许进行并发处理的情况下.比如系统对接
//6:nowait  false不返回执行结果,但是如果排他开启的话,则必须需要等待结果的,如果两个一起开就会报错
//7:callback  null回调函数
//8:ticket  null
//9:arguments null
$channel->basic_consume($queueName, '', false, true, false, false, function($msg){
    var_dump($msg->delivery_info);
    $msg->delivery_info['channel']->basic_ack($msg->delivery_info['delivery_tag']);//手动应答
});
//监听消息
while(count($channel->callbacks)){
    $channel->wait();
}

$msgBody = json_encode(["msg" => "hello"]);
$msg     = new AMQPMessage($msgBody, ['content_type' => 'text/plain', 'delivery_mode' => 2]); //生成消息
$r       = $channel->basic_publish($msg, $exchangeName, $routingKey); //推送消息到某个交换机
$channel->close();
$conn->close();
