消息推送系统

<?php

// 示例代码：统一消息平台中的消息发送模块

class MessageSender {

private $queue;

public function __construct($queue) {

$this->queue = $queue;

}

public function sendMessage($message, $recipient) {

// 模拟将消息放入队列的过程

$this->queue->enqueue($message);

echo "Message sent to $recipient\n";

}

}

// 使用消息队列（例如RabbitMQ）作为消息传递机制

require_once 'vendor/autoload.php';

use PhpAmqpLib\Connection\AMQPStreamConnection;

use PhpAmqpLib\Message\AMQPMessage;

class RabbitMQQueue {

private $connection;

private $channel;

private $queueName;

public function __construct($host, $port, $username, $password, $queueName) {

$this->connection = new AMQPStreamConnection($host, $port, $username, $password);

$this->channel = $this->connection->channel();

list(, , $this->queueName) = $this->channel->queue_declare($queueName, false, false, false, false);

}

public function enqueue($message) {

$msg = new AMQPMessage($message);

$this->channel->basic_publish($msg, '', $this->queueName);

}

选排课系统

public function close() {

$this->channel->close();

$this->connection->close();

}

}

// 实例化MessageSender和RabbitMQQueue对象

$queue = new RabbitMQQueue('localhost', 5672, 'guest', 'guest', 'message_queue');

$sender = new MessageSender($queue);

// 发送一条测试消息

$sender->sendMessage('Hello, world!', 'user1');

$queue->close();
