PHP使用enqueue/amqp-lib实现rabbitmq任务处理

2024-03-11 11:54:22 作者：huaweichenai

这篇文章主要为大家详细介绍了PHP如何使用enqueue/amqp-lib实现rabbitmq任务处理,文中的示例代码讲解详细,感兴趣的小伙伴可以学习一下

一：拓展安装

composer require enqueue/amqp-lib

文档地址：https://github.com/php-enqueue/enqueue-dev/blob/master/docs/transport/amqp_lib.md

二：方法介绍

1：连接rabbitmq

$factory = new AmqpConnectionFactory([
    'host' => '192.168.6.88',//host
    'port' => '5672',//端口
    'vhost' => '/',//虚拟主机
    'user' => 'admin',//账号
    'pass' => 'admin',//密码
]);
$context = $factory->createContext();

2：声明主题

//声明并创建主题
$exchangeName = 'exchange';
$fooTopic = $context->createTopic($exchangeName);
$fooTopic->setType(AmqpTopic::TYPE_FANOUT);
$context->declareTopic($fooTopic);
 
//删除主题
$context->deleteTopic($fooTopic);

3：声明队列

//声明并创建队列
$queueName = 'rabbitmq';
$fooQueue = $context->createQueue($queueName);
$fooQueue->addFlag(AmqpQueue::FLAG_DURABLE);
$context->declareQueue($fooQueue);
 
//删除队列
$context->deleteQueue($fooQueue);

4：将队列绑定到主题

$context->bind(new AmqpBind($fooTopic, $fooQueue));

5：发送消息

//向队列发送消息
$message = $context->createMessage('Hello world!');
$context->createProducer()->send($fooQueue, $message);
 
//向队列发送优先消息
$queueName = 'rabbitmq';
$fooQueue = $context->createQueue(queueName);
$fooQueue->addFlag(AmqpQueue::FLAG_DURABLE);
//设置队列的最大优先级
$fooQueue->setArguments(['x-max-priority' => 10]);
$context->declareQueue($fooQueue);
 
$message = $context->createMessage('Hello world!');
 
$context->createProducer()
    ->setPriority(5) //设置优先级，优先级越高，消息越快到达消费者
    ->send($fooQueue, $message);
 
//向队列发送延时消息
$message = $context->createMessage('Hello world!');
 
$context->createProducer()
    ->setDelayStrategy(new RabbitMqDlxDelayStrategy())
    ->setDeliveryDelay(5000) //消息延时5秒
    ->send($fooQueue, $message);

6：消费消息【接收消息】

//消费消息
$consumer = $context->createConsumer($fooQueue);
 
$message = $consumer->receive();
 
// process a message
//业务代码
 
$consumer->acknowledge($message);//ack应答，通知rabbitmq成功，删除对应任务
// $consumer->reject($message);ack应答，通知rabbitmq失败，不删除对应任务
 
 
//订阅消费者
$fooConsumer = $context->createConsumer($fooQueue);
 
$subscriptionConsumer = $context->createSubscriptionConsumer();
$subscriptionConsumer->subscribe($fooConsumer, function(Message $message, Consumer $consumer) {
    // process message
    //业务代码
    $consumer->acknowledge($message);//ack应答，通知rabbitmq成功，删除对应任务
    // $consumer->reject($message);ack应答，通知rabbitmq失败，不删除对应任务
 
    return true;
});
$subscriptionConsumer->consume();
 
//清除队列消息
$queueName = 'rabbitmq';
$queue = $context->createQueue($queueName);
$context->purgeQueue($queue);

三：简单实现

1：发送消息

//连接rabbitmq
$factory = new AmqpConnectionFactory([
    'host' => '192.168.6.88',
    'port' => '5672',
    'vhost' => '/',
    'user' => 'admin',
    'pass' => 'admin',
    'persisted' => false,
]);
 
$context = $factory->createContext();
//声明主题
$exchangeName = 'exchange';
$fooTopic = $context->createTopic($exchangeName);
$fooTopic->setType(AmqpTopic::TYPE_FANOUT);
$context->declareTopic($fooTopic);
 
//声明队列
$queueName = 'rabbitmq';
$fooQueue = $context->createQueue($queueName);
$fooQueue->addFlag(AmqpQueue::FLAG_DURABLE);
$context->declareQueue($fooQueue);
 
//将队列绑定到主题
$context->bind(new AmqpBind($fooTopic, $fooQueue));
 
//发送消息到队列
$message = $context->createMessage('Hello world!');
 
$context->createProducer()->send($fooQueue, $message);

2：消费消息

$factory = new AmqpConnectionFactory([
    'host' => '192.168.6.88',
    'port' => '5672',
    'vhost' => '/',
    'user' => 'admin',
    'pass' => 'admin',
    'persisted' => false,
]);
$context = $factory->createContext();
 
 
$queueName = 'rabbitmq';
$fooQueue = $context->createQueue($queueName);
 
 
 
$fooConsumer = $context->createConsumer($fooQueue);
 
$subscriptionConsumer = $context->createSubscriptionConsumer();
$subscriptionConsumer->subscribe($fooConsumer, function(Message $message, Consumer $consumer) {
    // process message
    //业务代码
    $consumer->acknowledge($message);//ack应答，通知rabbitmq成功，删除对应任务
    // $consumer->reject($message);ack应答，通知rabbitmq失败，不删除对应任务
 
    return true;
});
$subscriptionConsumer->consume();
