    PHP中RabbitMQ之amqp扩展实现

    参考地址:https://blog.csdn.net/yeyun666/article/details/85112742

    在安装完成后我们就可以开始我们的RabbitMQ之旅了,本Demo示例只创建了一个直连交换机,共有四个文件Consum.php (消费者),Publish.php (生产者) ,RabbitMqParernt.php (自己封装的RabbitMQ的方法) ,以及test.php (测试数据)

    RabbitMqParernt.php如下所

    <?php

    abstract class RabbitMqParernt

    {

        //rabbitMQ配置信息(默认配置)

        public $config = array(

            'host'=>'127.0.0.1',  //host

    'port'=>5672,        //端口

    'username'=>'guest',  //账号

    'password'=>'guest',  //密码

    'vhost'=>'/'          //虚拟主机

    );

    public $exchangeName = ''; //交换机

        public $queueName = '';    //队列名

        public $routeKey = '';    //路由键

    public $exchangeType = '';  //交换机类型

    public $channel;      //信道

        public $connection;   //连接

    public $exchange;    //交换机

        public $queue;        //队列

    //初始化RabbitMQ($config数组是用来修改rabbitMQ的配置信息的)

    public function __construct($exchangeName, $queueName, $routeKey, $exchangeType = '',$config = array())

    {

    $this->exchangeName = $exchangeName;

            $this->queueName = $queueName;

            $this->routeKey = $routeKey;

    $this->exchangeType = $exchangeType;

    if(!empty($config))

    {

    $this->setConfig($config);

    }

    $this->createConnet();

    }

        //对RabbitMQ的配置重新进行配置

    public function setConfig($config)

    {

    if (!is_array($config))

    {

                throw new Exception('config不是一个数组');

            }

    foreach($config as $key => $value)

    {

    $this->config[$key] = $value;

    }

    }

    //创建连接与信道

    public function createConnet()

    {

    //创建连接

    $this->connection = new AMQPConnection($this->config);

    if(!$this->connection->connect())

    {

    throw new Exception('RabbitMQ创建连接失败');

    }

    //创建信道

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

    //创建交换机

    $this->createExchange();

    //生产时不需要队列,故队列名为空,只有消费时需要队列名

    if(!empty($this->queueName))

    {

    $this->createQueue();

    }

    }

    //创建交换机

    public function createExchange()

    {

    $this->exchange = new AMQPExchange($this->channel);   

    $this->exchange->setName($this->exchangeName);

            $this->exchange->setType(AMQP_EX_TYPE_DIRECT); 

    $this->exchange->setFlags(AMQP_DURABLE);

    }

    //创建队列,绑定交换机

    public function createQueue()

    {

    $this->queue = new AMQPQueue($this->channel);

    $this->queue->setName($this->queueName);

    $this->queue->setFlags(AMQP_DURABLE);

    $this->queue->bind($this->exchangeName, $this->routeKey);

    }

    public function dealMq($flag)

    {

    if($flag)

    {

    $this->queue->consume(function($envelope){$this->getMsg($envelope, $this->queue);},AMQP_AUTOACK);//自动ACK应答

    }

    else

    {

    $this->queue->consume(function($envelope){$this->processMessage($envelope, $this->queue);});

    }

    }

    public function getMsg($envelope, $queue)

    {

    $msg = $envelope->getBody();

    $this->doProcess($msg);

    }

    public function processMessage($envelope, $queue)

    {

    $msg = $envelope->getBody(); 

            $this->doProcess($msg);

            $queue->ack($envelope->getDeliveryTag()); //手动发送ACK应答

    }

    //处理消息的真正函数,在消费者里使用

    abstract public function doProcess($msg);   

        //发送消息

    public function sendMessage($message)

    {  

            $this->exchange->publish($message, $this->routeKey);   

    }

    //关闭连接

    public function closeConnect()

    {

    $this->channel->close();

    $this->connection->disconnect();

    }

    }

     Consum.php 如下所示

    <?php

    include_once('RabbitMqParernt.php');

    class Consum extends RabbitMqParernt

    {

        public function __construct()

        {

            parent::__construct('exchange', 'queue', 'routeKey');

        }

        public function doProcess($msg)

        {

            echo $msg;

        }

    }

    $consum = new Consum();

    //$consum->dealMq(false);

    $consum->dealMq(true);

    Publish.php如下所示

    <?php

    include_once('RabbitMqParernt.php');

    class Publish extends RabbitMqParernt

    {

        public function __construct()

        {

            parent::__construct('exchange', '', 'routeKey');

        }

        public function doProcess($msg)

        {

        }

    }
