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：
