配置环境
windows + nginx + php7.2.19
php扩展添加
根据自己的版本下载扩展http://pecl.php.net/package/amqp
下载完成后把rabbitmq.4.dll放php.exe所在目录，php_amqp.dll放php的ext目录然后在php.ini中添加 extension=php_amqp.dll重启后查看扩展信息。
如果是apache的话要在httpd.conf中添加
loadFile "你的路径/rabbitmq.4.dll";
使用方法
服务端(消费者)代码<?php
//配置信息
$conn_args = array(
'host' => '127.0.0.1',
'port' => '5672',
'login' => 'guest',
'password' => 'guest',
'vhost' => '/',
);
$e_name = 'e_test'; //交换机名
$q_name = 'q_test'; //队列名
$k_route = 'route_test'; //路由key
//创建连接和channel
$conn = new AMQPConnection($conn_args);
if (!$conn->connect()) {
die("Cannot connect to the broker!\n");
}
//在连接内创建一个通道
$channel = new AMQPChannel($conn);
//创建交换机
$ex = new AMQPExchange($channel);
$ex->setName($e_name);
//设置交换机类型
//AMQP_EX_TYPE_DIRECT:直连交换机
//AMQP_EX_TYPE_FANOUT:扇形交换机
//AMQP_EX_TYPE_HEADERS:头交换机
//AMQP_EX_TYPE_TOPIC:主题交换机
$ex->setType(AMQP_EX_TYPE_DIRECT);
//设置交换机持久
$ex->setFlags(AMQP_DURABLE);
//声明交换机并输出状态
echo "Exchange Status:" . $ex->declareExchange() . "\n";
//创建队列
$q = new AMQPQueue($channel);
$q->setName($q_name);
//设置队列持久
$q->setFlags(AMQP_DURABLE);
//声明消息队列并输出状态
echo "Message Total:" . $q->declareQueue() . "\n";
//绑定交换机与队列，并指定路由键
echo 'Queue Bind: ' . $q->bind($e_name, $k_route) . "\n";
//阻塞模式接收消息
echo "waiting reeive Message...\n";
//接收消息并进行处理的回调方法
function processMessage($envelope, $queue)
{
//取消息内容
$msg = $envelope->getBody();
echo $msg . "\n"; //处理消息
//显式确认，队列收到消费者显式确认后，会删除该消息
$queue->ack($envelope->getDeliveryTag());
}
//设置消息队列消费者回调方法，并进行阻塞
$q->consume('processMessage');
//下面是隐式确认,不推荐
//$q->consume('processMessage', AMQP_AUTOACK);
$conn->disconnect();
客户端(生产者)代码<?php
//配置信息
$conn_args = array(
'host' => '127.0.0.1',
'port' => '5672',
'login' => 'guest',
'password' => 'guest',
'vhost' => '/',
);
$e_name = 'e_test'; //交换机名,和服务端一至
$k_route = 'route_test'; //路由key，和服务端一至
//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);
//创建交换机对象
$ex = new AMQPExchange($channel);
$ex->setName($e_name);
$ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型
$ex->setFlags(AMQP_DURABLE); //持久化
$ex->declareExchange();
//发送消息
//$channel->startTransaction(); //开始事务
for ($i = 0; $i
//sleep(1); //休眠1秒
//消息内容
$message = "TEST MESSAGE!" . date("h:i:sa");
echo "Send Message:" . $ex->publish($message, $k_route) . "\n";
}
//$channel->commitTransaction(); //提交事务
$conn->disconnect();
使用说明
交换机，路由键，队列，如果细细了解的话要学习的东西就多啦去啦，项目中使用一般会有这样的场景，搭建一个消息队列中心来接收和处理多个项目发过来的消息，一个项目中可能会有多个消息类型，比如评论消息、秒杀下单消息、日志消息等。我们可以使用项目名字和消息类型来创建对应的交换机，路由和队列。项目名字->交换机名字
消息类型->路由键名字
消息类型->队列名字
生产者生产消息的时候只用标识是哪个项目的哪个消息直接发出去就ok，下面是这种方案的一个实现,代码保存为 MessageQueue.php
