PHP实现延时队列和处理超时订单

今天小编就为大家带来一篇有关PHP实现延时队列和处理超时订单的文章。小编觉得挺实用的，为此分享给大家做个参考。一起跟随小编过来看看吧。

延时队列

• Delayproducer.Php

• Amqpbuilder.Php

AmqpBuilder.php

arguments = array_merge($this->arguments, $arguments);        return $this;    }    /**     * 设置延时队列相关参数     *     * @param string $queueName     * @param int    $xMessageTtl     * @param string $xDeadLetterExchange     * @param string $xDeadLetterRoutingKey     *     * @return $this     */    public function setDelayedQueue(string $queueName, int $xMessageTtl, string $xDeadLetterExchange, string $xDeadLetterRoutingKey) : self    {        $this->setArguments([            'x-message-ttl'             => ['I', $xMessageTtl * 1000], // 毫秒            'x-dead-letter-exchange'    => ['S', $xDeadLetterExchange],            'x-dead-letter-routing-key' => ['S', $xDeadLetterRoutingKey],        ]);        $this->setQueue($queueName);        return $this;    }}

DelayProducer.php

produceMessage($producerMessage, $queueBuilder, $confirm, $timeout);        });    }    /**     * @param ProducerMessageInterface $producerMessage     * @param AmqpBuilder              $queueBuilder     * @param bool                     $confirm     * @param int                      $timeout     *     * @return bool     * @throws \Throwable     */    private function produceMessage(ProducerMessageInterface $producerMessage, AmqpBuilder $queueBuilder, bool $confirm = false, int $timeout = 5) : bool    {        $result = false;        $this->injectMessageProperty($producerMessage);        $message = new AMQPMessage($producerMessage->payload(), $producerMessage->getProperties());        $pool    = $this->getConnectionPool($producerMessage->getPoolName());        /** @var \Hyperf\Amqp\Connection $connection */        $connection = $pool->get();        if ($confirm) {            $channel = $connection->getConfirmChannel();        } else {            $channel = $connection->getChannel();        }        $channel->set_ack_handler(function () use (&$result)        {            $result = true;        });        try {            // 处理延时队列            $exchangeBuilder = $producerMessage->getExchangeBuilder();            // 队列定义            $channel->queue_declare($queueBuilder->getQueue(), $queueBuilder->isPassive(), $queueBuilder->isDurable(), $queueBuilder->isExclusive(), $queueBuilder->isAutoDelete(), $queueBuilder->isNowait(), $queueBuilder->getArguments(), $queueBuilder->getTicket());            // 路由定义            $channel->exchange_declare($exchangeBuilder->getExchange(), $exchangeBuilder->getType(), $exchangeBuilder->isPassive(), $exchangeBuilder->isDurable(), $exchangeBuilder->isAutoDelete(), $exchangeBuilder->isInternal(), $exchangeBuilder->isNowait(), $exchangeBuilder->getArguments(), $exchangeBuilder->getTicket());            // 队列绑定            $channel->queue_bind($queueBuilder->getQueue(), $producerMessage->getExchange(), $producerMessage->getRoutingKey());            // 消息发送            $channel->basic_publish($message, $producerMessage->getExchange(), $producerMessage->getRoutingKey());            $channel->wait_for_pending_acks_returns($timeout);        } catch (Throwable $exception) {            // Reconnect the connection before release.            $connection->reconnect();            throw $exception;        }        finally {            $connection->release();        }        return $confirm ? $result : true;    }    /**     * @param ProducerMessageInterface $producerMessage     */    private function injectMessageProperty(ProducerMessageInterface $producerMessage) : void    {        if (class_exists(AnnotationCollector::class)) {            /** @var \Hyperf\Amqp\Annotation\Producer $annotation */            $annotation = AnnotationCollector::getClassAnnotation(get_class($producerMessage), Producer::class);            if ($annotation) {                $annotation->routingKey && $producerMessage->setRoutingKey($annotation->routingKey);                $annotation->exchange && $producerMessage->setExchange($annotation->exchange);            }        }    }}

处理超时订单

• Orderqueueconsumer.Php

• Orderqueueproducer.Php

Orderqueueproducer.php

payload = $data;    }    public function getExchangeBuilder() : ExchangeBuilder    {        return parent::getExchangeBuilder(); // TODO: Change the autogenerated stub    }}

Orderqueueconsumer.php

Demo
$builder = new AmqpBuilder();        $builder->setDelayedQueue('order_exchange', 1, 'delay_exchange', 'delay_route');        $que = ApplicationContext::getContainer()->get(DelayProducer::class);        var_dump($que->produce(new OrderQueueProducer(['order_sn' => (string)mt_rand(10000, 90000)]), $builder))
