rabitmq的简单使用

send.php

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

$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();
//1.对列名2.是否持久化队列(默认在内存重启会丢失。如果为true会存在他自带的数据库中)3.是否排外(作用:a.当连接关闭后是否会自动删除队列b.是否私有当前队列,如果私有了,其他通道不可以访问当前队列.如果为true,一般是一个队列只适用于一个消费者的时候)4.是否自动删除5.我们的一些其他参数.
//声明队列,如果存在则什么都不做，如果不存在则创建
$channel->queue_declare('hello', false, false, false, false);

$msg = new AMQPMessage('Hello Worldsdfsfs!');
$channel->basic_publish($msg, '', 'hello');

echo " [x] Sent 'Hello World!'\n";
$channel->close();
$connection->close();

receive.php

<?php
require_once __DIR__ . '/vendor/autoload.php';
use PhpAmqpLib\Connection\AMQPStreamConnection;
$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();
$channel->queue_declare('hello', false, false, false, false);
echo " [*] Waiting for messages. To exit press CTRL+C\n";
$callback = function ($msg) {
    echo ' [x] Received ', $msg->body, "\n";
};
//消息处理方式:阻塞。用 $q->consum( callback, [...] ) 程序会进入持续侦听状态，每收到一个消息就会调用callback指定的函数一次，直到某个callback函数返回FALSE才结束。
//a.方式处理
//$channel->basic_consume('hello', '', false, true, false, false, $callback);
//b.类处理
$c = new gg();
$channel->basic_consume('hello', '', false, true, false, false, [$c,'myfunc']);
while (count($channel->callbacks)) {
    $channel->wait();
}
$channel->close();
$connection->close();
class gg{
	function myfunc($msg){
		echo '123'.PHP_EOL;
		var_dump($msg);
	}	
}

new_task.php

<?php

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

$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();

$channel->queue_declare('task_queue', false, true, false, false);

$data = implode(' ', array_slice($argv, 1));
if (empty($data)) {
    $data = "Hello World!";
}
$msg = new AMQPMessage(
    $data,
    array('delivery_mode' => AMQPMessage::DELIVERY_MODE_PERSISTENT)
);

$channel->basic_publish($msg, '', 'task_queue');

echo ' [x] Sent ', $data, "\n";

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

worker.php

<?php

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

$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();
$channel->queue_declare('task_queue', false, true, false, false);

echo " [*] Waiting for messages. To exit press CTRL+C\n";

$callback = function ($msg) {
    echo ' [x] Received ', $msg->body, "\n";
    sleep(substr_count($msg->body, '.'));
    echo " [x] Done\n";
    $msg->delivery_info['channel']->basic_ack($msg->delivery_info['delivery_tag']);
};
//公平转发
//诉RabbitMQ，再同一时刻，不要发送超过1条消息给一个工作者（worker），直到它已经处理了上一条消息并且作出了响应
$channel->basic_qos(null, 1, null);
$channel->basic_consume('task_queue', '', false, false, false, false, $callback);

while (count($channel->callbacks)) {
    $channel->wait();
}

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