RibbetMQ php擴展使用 實現(xiàn)隊列生產(chǎn)消費

一般的隊列系統(tǒng)，是指linux中的crontab定時啟動腳本來處理任務:

首先下載一個rabbitmq的客戶端，他相當于一個容器，裝排隊數(shù)據(jù)的容器

http://www.rabbitmq.com/download.html

默認的端口是55672   訪問地址http://127.0.0.1:55672/

默認帳號密碼   guest    guest

你可以看到rabbitmq 的管理界面

mq的任務是一個不浪費資源，的一個隊列系統(tǒng)！

        php使用需要下載一個amqp擴展

         或者直接點擊下面的地址找到適合自己的版本，下載

            http://pecl.php.net/package/amqp/1.2.0/windows

            rabbitmq.1.dll   放在C盤windows下

            php_amqp.dll    放入php擴展中

            開啟php_amqp.dll的引用

            重啟服務器

用phpinfo();

查看是否引用成功，如果出現(xiàn)以下的amqp擴展，那就說明成功了

首先是rabbitmq的生產(chǎn)者：

    創(chuàng)建第一個index文件：然后去mq中查看，如果添加一個test001的隊列名信息，就說明已經(jīng)添加進去了，xx22的信息已經(jīng)在mq中存儲！

    接下來就需要跑數(shù)據(jù)了。

    createQueue(array('xxx','2222'),'test001');

    echo "ok";

     function createQueue($message,$queueName,$exchangeName = '', $queueKey = '')

    {

        $queueName = self::getQueueName($queueName);

        $conn_args = array('host' =>'localhost', 'port'=> '5672',

            'login' =>'guest',        //mq帳號

            'password'=> '',        //mq密碼

             'vhost' => '/');

        $conn = new AMQPConnection($conn_args);

        $conn->connect();

        $channel = new AMQPChannel($conn);

        if (!$exchangeName) {

            $exchangeName = $queueName;

        }

        $queueName = $queueName;

        if (!$queueKey) {

            $queueKey = $queueName;

        }

        $ex = new AMQPExchange($channel);

        $ex->setName($exchangeName);

        $ex->setType(AMQP_EX_TYPE_TOPIC);

        $ex->setFlags(AMQP_DURABLE); //exchange持久化

        $ex->declareExchange();

        $q = new AMQPQueue($channel);

        $q->setName($queueName);

        $q->setFlags(AMQP_DURABLE); //queue持久化

        $q->declareQueue();

        $q->bind($exchangeName, $queueKey);

        $channel->startTransaction();

        /**

         * 消息持久化,delivery_mode:2持久化、delivery_mode:1非持久化，其中priority是設置消息的優(yōu)先級，測試中發(fā)現(xiàn)并未起作用。

         * 消息還有其他屬性，請參考http://www.php.net/manual/zh/amqpexchange.publish.php

         */

        $result = $ex->publish(json_encode($message), $queueKey, AMQP_NOPARAM, array('delivery_mode'=>2, 'priority'=> 9));

        $channel->commitTransaction();

        $conn->disconnect();

    }  

有了生產(chǎn)者，那就有消費者。

腳本如果沒有其他的修改或問題，基本上都是常年啟動的：

消費者基類：

        class WorkerCommand{

        function qInit($q_name,$e_name='',$k_route=''){

                $q_name = Utils::getQueueName($q_name);

                $conn_args = array(

                    'host' => '127.0.0.1',            //mq的配置

                    'port' => '5672',

                    'login' => 'guest',

                    'password' => 'huoxingxing',

                    'vhost' => '/'

                );

        //創(chuàng)建連接和channel

                $conn = new AMQPConnection($conn_args);

                if (!$conn->connect()) {

                    die("Cannot connect to the broker!\n");

                }

                $channel = new AMQPChannel($conn);

        //創(chuàng)建交換機

                $ex = new AMQPExchange($channel);

                if (!$e_name) {

                    $e_name = $q_name;

                }

                $ex->setName($e_name);

                $ex->setType(AMQP_EX_TYPE_DIRECT); //direct類型

                $ex->setFlags(AMQP_DURABLE); //持久化

               // echo "Exchange Status:" . $ex->declareExchange() . "\n";

        //創(chuàng)建隊列

                $q = new AMQPQueue($channel);

                $q->setName($q_name);

                $q->setFlags(AMQP_DURABLE); //持久化

               // echo "Message Total:" . $q->declareExchange() . "\n";

                if (!$k_route) {

                    $k_route = $q_name;

                }

        //綁定交換機與隊列，并指定路由鍵

               // echo 'Queue Bind: ' . $q->declareQueue($e_name, $k_route) . "\n";

        //阻塞模式接收消息

                echo "Message:\n";

                while (True) {

                    $q->consume(array($this,'processMessage'));

                    //$q->consume('processMessage', AMQP_AUTOACK); //自動ACK應答

                }

                $conn->disconnect();

        }

}    

消費者：

class WorkerWareSyncBackUpCommand extends WorkerCommand {

    function actionIndex()

    {

        $this->qInit('SyncWareBackup');

    }

    function processMessage($envelope, $queue)

    {

        $msg = json_decode($envelope->getBody());

        Utils::doBackUp('back',$msg,'');

        $queue->ack($envelope->getDeliveryTag()); //手動發(fā)送ACK應答

    }

}
