這篇文章主要為大家詳細(xì)介紹了PHP如何使用enqueue/amqp-lib實(shí)現(xiàn)rabbitmq任務(wù)處理,文中的示例代碼講解詳細(xì),感興趣的小伙伴可以學(xué)習(xí)一下

一：拓展安裝

composer require enqueue/amqp-lib

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

二：方法介紹

1：連接rabbitmq

$factory = new AmqpConnectionFactory([
    'host' => '192.168.6.88',//host
    'port' => '5672',//端口
    'vhost' => '/',//虛擬主機(jī)
    'user' => 'admin',//賬號(hào)
    'pass' => 'admin',//密碼
]);
$context = $factory->createContext();

2：聲明主題

//聲明并創(chuàng)建主題
$exchangeName = 'exchange';
$fooTopic = $context->createTopic($exchangeName);
$fooTopic->setType(AmqpTopic::TYPE_FANOUT);
$context->declareTopic($fooTopic);
 
//刪除主題
$context->deleteTopic($fooTopic);

3：聲明隊(duì)列

//聲明并創(chuàng)建隊(duì)列
$queueName = 'rabbitmq';
$fooQueue = $context->createQueue($queueName);
$fooQueue->addFlag(AmqpQueue::FLAG_DURABLE);
$context->declareQueue($fooQueue);
 
//刪除隊(duì)列
$context->deleteQueue($fooQueue);

4：將隊(duì)列綁定到主題

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

5：發(fā)送消息

//向隊(duì)列發(fā)送消息
$message = $context->createMessage('Hello world!');
$context->createProducer()->send($fooQueue, $message);
 
//向隊(duì)列發(fā)送優(yōu)先消息
$queueName = 'rabbitmq';
$fooQueue = $context->createQueue(queueName);
$fooQueue->addFlag(AmqpQueue::FLAG_DURABLE);
//設(shè)置隊(duì)列的最大優(yōu)先級(jí)
$fooQueue->setArguments(['x-max-priority' => 10]);
$context->declareQueue($fooQueue);
 
$message = $context->createMessage('Hello world!');
 
$context->createProducer()
    ->setPriority(5) //設(shè)置優(yōu)先級(jí)，優(yōu)先級(jí)越高，消息越快到達(dá)消費(fèi)者
    ->send($fooQueue, $message);
 
//向隊(duì)列發(fā)送延時(shí)消息
$message = $context->createMessage('Hello world!');
 
$context->createProducer()
    ->setDelayStrategy(new RabbitMqDlxDelayStrategy())
    ->setDeliveryDelay(5000) //消息延時(shí)5秒
    ->send($fooQueue, $message);

6：消費(fèi)消息【接收消息】

//消費(fèi)消息
$consumer = $context->createConsumer($fooQueue);
 
$message = $consumer->receive();
 
// process a message
//業(yè)務(wù)代碼
 
$consumer->acknowledge($message);//ack應(yīng)答，通知rabbitmq成功，刪除對(duì)應(yīng)任務(wù)
// $consumer->reject($message);ack應(yīng)答，通知rabbitmq失敗，不刪除對(duì)應(yīng)任務(wù)
 
 
//訂閱消費(fèi)者
$fooConsumer = $context->createConsumer($fooQueue);
 
$subscriptionConsumer = $context->createSubscriptionConsumer();
$subscriptionConsumer->subscribe($fooConsumer, function(Message $message, Consumer $consumer) {
    // process message
    //業(yè)務(wù)代碼
    $consumer->acknowledge($message);//ack應(yīng)答，通知rabbitmq成功，刪除對(duì)應(yīng)任務(wù)
    // $consumer->reject($message);ack應(yīng)答，通知rabbitmq失敗，不刪除對(duì)應(yīng)任務(wù)
 
    return true;
});
$subscriptionConsumer->consume();
 
//清除隊(duì)列消息
$queueName = 'rabbitmq';
$queue = $context->createQueue($queueName);
$context->purgeQueue($queue);

三：簡單實(shí)現(xiàn)

1：發(fā)送消息

//連接rabbitmq
$factory = new AmqpConnectionFactory([
    'host' => '192.168.6.88',
    'port' => '5672',
    'vhost' => '/',
    'user' => 'admin',
    'pass' => 'admin',
    'persisted' => false,
]);
 
$context = $factory->createContext();
//聲明主題
$exchangeName = 'exchange';
$fooTopic = $context->createTopic($exchangeName);
$fooTopic->setType(AmqpTopic::TYPE_FANOUT);
$context->declareTopic($fooTopic);
 
//聲明隊(duì)列
$queueName = 'rabbitmq';
$fooQueue = $context->createQueue($queueName);
$fooQueue->addFlag(AmqpQueue::FLAG_DURABLE);
$context->declareQueue($fooQueue);
 
//將隊(duì)列綁定到主題
$context->bind(new AmqpBind($fooTopic, $fooQueue));
 
//發(fā)送消息到隊(duì)列
$message = $context->createMessage('Hello world!');
 
$context->createProducer()->send($fooQueue, $message);

2：消費(fèi)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
    //業(yè)務(wù)代碼
    $consumer->acknowledge($message);//ack應(yīng)答，通知rabbitmq成功，刪除對(duì)應(yīng)任務(wù)
    // $consumer->reject($message);ack應(yīng)答，通知rabbitmq失敗，不刪除對(duì)應(yīng)任務(wù)
 
    return true;
});
$subscriptionConsumer->consume();
