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' => '5672',
'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' => '5672',
'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","000000",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(11) NOT NULL AUTO_INCREMENT,
`sJson` varchar(255) 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' => '5672', '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($i=0;$i<10;$i++){
if($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'=> '5672', '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' => '5672',
'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=0; $i<5; ++$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' => '5672',
'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
