要使用php的amqplib库实现消息持久化,你需要在创建队列和交换机时设置一些参数。以下是一个简单的示例:
composer require php-amqplib/php-amqplib
publisher.php
的文件,用于发送持久化消息:<?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();
// 创建一个持久化的交换机
$channel->exchange_declare('persistent_exchange', 'direct', false, true, false);
// 创建一个持久化的队列
$channel->queue_declare('persistent_queue', false, true, false, false);
// 将队列绑定到交换机
$channel->queue_bind('persistent_queue', 'persistent_exchange');
// 创建一个持久化的消息
$msg = new AMQPMessage('Hello, persistent message!', array('delivery_mode' => AMQPMessage::DELIVERY_MODE_PERSISTENT));
// 发送消息到交换机
$channel->basic_publish($msg, 'persistent_exchange');
echo "Sent persistent message!\n";
$channel->close();
$connection->close();
consumer.php
的文件,用于接收持久化消息:<?php
require_once __DIR__ . '/vendor/autoload.php';
use PhpAmqpLib\Connection\AMQPStreamConnection;
$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();
// 创建一个持久化的队列
$channel->queue_declare('persistent_queue', false, true, false, false);
echo "Waiting for messages...\n";
$callback = function ($msg) {
echo 'Received: ', $msg->body, "\n";
};
// 消费持久化消息
$channel->basic_consume('persistent_queue', '', false, true, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
$channel->close();
$connection->close();
publisher.php
文件发送持久化消息:php publisher.php
consumer.php
文件接收持久化消息:php consumer.php
这样,你就成功地使用php的amqplib库实现了消息持久化。当RabbitMQ服务器重启后,持久化的消息仍然会存在。
