RabbitMQ学习之（四）_PHP操作RabbitMQ简单Demo

原理流程

生产者主要做的是：创建连接-->创建channel-->创建交换机对象-->发送消息

消费者主要做的是：创建连接-->创建channel-->创建交换机-->创建队列-->绑定交换机/队列/路由键-->接收消息

案例一：

生产者

<?php

$conn_args = array(

    'host' => '127.0.0.1',

    'port' => '',

    'login' => 'admin',

    'password' => 'admin',

    'vhost'=>'/'

);

$content = isset($_GET['content']) ? htmlspecialchars($_GET['content']) : '请输入消息';

//创建连接和channel

$conn = new AMQPConnection($conn_args);

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

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

}

$channel = new AMQPChannel($conn);

//创建交换机

$e_name = 'e_linvo'; //交换机名

$ex = new AMQPExchange($channel);

$ex->setName($e_name);

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

$ex->setFlags(AMQP_DURABLE); //持久化

$ex->declare();

//echo "Send Message:".$ex->publish("TEST MESSAGE，key_1 by xust" . date('H:i:s', time()), 'key_1')."\n";

//echo "Send Message:".$ex->publish("TEST MESSAGE，key_2 by xust" . date('H:i:s', time()), 'key_2')."\n";

$ex->publish($content, 'key_1');

echo "finish\n";  

消费者

<?php

$conn_args = array(

    'host' => '127.0.0.1',

    'port' => '',

    'login' => 'admin',

    'password' => 'admin',

    'vhost'=>'/'

);

$e_name = 'e_linvo'; //交换机名

$q_name = 'q_linvo'; //队列名

$k_route = 'key_2'; //路由key

//创建连接和channel

$conn = new AMQPConnection($conn_args);

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

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

}

$channel = new AMQPChannel($conn);

//创建交换机

$ex = new AMQPExchange($channel);

$ex->setName($e_name);

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

$ex->setFlags(AMQP_DURABLE); //持久化

$ex->declare();

//创建队列

$q = new AMQPQueue($channel);

$q->setName($q_name);

$q->setFlags(AMQP_DURABLE); //持久化

$q->declare();     //最好队列object在这里declare()下，否则如果是新的queue会报错

//绑定交换机与队列，并指定路由键，可以多个路由键

$q->bind($e_name, 'key_1');

//$q->bind($e_name, 'key_33');

//阻塞模式接收消息

echo "Message:\n";

$q->consume('processMessage', AMQP_AUTOACK); //自动ACK应答

$conn->disconnect();

/**

 * 消费回调函数

 * 处理消息

 */

function processMessage($envelope, $queue) {

    var_dump($envelope->getRoutingKey());

    $msg = $envelope->getBody();

    mysql_insert($msg);

}

//消息入库

function mysql_insert($json){

   $pdo = new PDO("mysql:host=localhost;dbname=rabbitmq","root","",array(PDO::ATTR_PERSISTENT => true) );

   $sql = "insert into rabbitmq_table(sJson) values ('{$json}')";

   echo $sql."\n";

    if ($pdo->exec($sql)){

        echo "insert success\n";

    } else {

        echo "error\n";

    }

}  

//表结构

DROP TABLE IF EXISTS `rabbitmq_table`;

CREATE TABLE `rabbitmq_table` (

  `id` int() NOT NULL AUTO_INCREMENT,

  `sJson` varchar() NOT NULL DEFAULT '',

  PRIMARY KEY (`id`)

) ENGINE=MyISAM DEFAULT CHARSET=utf8;

启动消费者程序，同时不断请求生产者程序，查看数据变化

案例二：

生产者

<?php

$routingkey='key2';

//设置你的连接

$conn_args = array('host' => 'localhost', 'port' => '', 'login' => 'admin', 'password' => 'admin');

$conn = new AMQPConnection($conn_args);

if ($conn->connect()) {

    echo "链接成功\n";

}else {

    echo "链接失败 \n ";

}

//你的消息

$message = json_encode(array('消息测试','My RabbitMQ-PHP','消息队列'));

//创建channel

$channel = new AMQPChannel($conn);

//创建exchange

$ex = new AMQPExchange($channel);

$ex->setName('exchange');//创建名字

$ex->setType(AMQP_EX_TYPE_DIRECT);

$ex->setFlags(AMQP_DURABLE);

//$ex->setFlags(AMQP_AUTODELETE);

//echo "exchange status:".$ex->declare();

echo "exchange status:".$ex->declareExchange();

echo "\n";

for($i=;$i<;$i++){

        if($routingkey=='key2'){

                $routingkey='key';

        }else{

                $routingkey='key2';

        }

        $ex->publish($message,$routingkey);

}

消费者

<?php

$bindingkey='key2';

//连接RabbitMQ

$conn_args = array( 'host'=>'127.0.0.1' , 'port'=> '', 'login'=>'admin' , 'password'=> 'admin','vhost' =>'/');

$conn = new AMQPConnection($conn_args);

$conn->connect();

//设置queue名称，使用exchange，绑定routingkey

$channel = new AMQPChannel($conn);

$q = new AMQPQueue($channel);

$q->setName('queue2');

$q->setFlags(AMQP_DURABLE);

$q->declare();

$q->bind('exchange',$bindingkey);

//消息获取

$messages = $q->get(AMQP_AUTOACK) ;

if ($messages){

var_dump(json_decode($messages->getBody(), true ));

}

$conn->disconnect();

案例三：

生产者

<?php

$conn_args = array(

    'host' => '127.0.0.1',

    'port' => '',

    'login' => 'admin',

    'password' => 'admin',

    'vhost'=>'/'

);

$e_name = 'e_linvo'; //交换机名

//$q_name = 'q_linvo'; //无需队列名

$k_route = 'key_1'; //路由key

//创建连接和channel

$conn = new AMQPConnection($conn_args);

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

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

}

$channel = new AMQPChannel($conn);

//消息内容

$message = "我的RabbitMQ走通了~~";

//创建交换机对象

$ex = new AMQPExchange($channel);

$ex->setName($e_name);

//发送消息

//$channel->startTransaction(); //开始事务

for($i=; $i<; ++$i){

    echo "Send Message:".$ex->publish($message, $k_route)."\n";

}

//$channel->commitTransaction(); //提交事务

$conn->disconnect();

消费者

<?php

//配置信息

$conn_args = array(

    'host' => '127.0.0.1',

    'port' => '',

    'login' => 'admin',

    'password' => 'admin',

    'vhost'=>'/'

);

$e_name = 'e_linvo'; //交换机名

$q_name = 'q_linvo'; //队列名

$k_route = 'key_1'; //路由key

//创建连接和channel

$conn = new AMQPConnection($conn_args);

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

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

}

$channel = new AMQPChannel($conn);

//创建交换机

$ex = new AMQPExchange($channel);

$ex->setName($e_name);

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

$ex->setFlags(AMQP_DURABLE); //持久化

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

//创建队列

$q = new AMQPQueue($channel);

$q->setName($q_name);

$q->setFlags(AMQP_DURABLE); //持久化

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

//绑定交换机与队列，并指定路由键

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

//阻塞模式接收消息

echo "Message:\n";

while(True){

    $q->consume('processMessage');

    //$q->consume('processMessage', AMQP_AUTOACK); //自动ACK应答

}

$conn->disconnect();

/**

* 消费回调函数

* 处理消息

*/

function processMessage($envelope, $queue) {

    $msg = $envelope->getBody();

    echo $msg."\n"; //处理消息

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

}

然后分别命令行执行两个程序，消费者程序处于监听状态，多次执行生产者测试，观察效果

php /data/wwwroot/default/publisher.php  //执行生产者

php /data/wwwroot/default/consumer.php  //执行消费者

附加删除队列：
