php操作rabbitMQ

阅读：567 发布：2019-04-09 作者：lypeng

我是Windows中操作的，下载扩展安装，编写代码测试

## 下载php_amqp扩展安装
1. 去php官网下载扩展
目前我用的php7.1.20_x64_nts版本！
php_amqp.dll 扔到 D:\phpStudy\php\php-7.1.20-nts\ext目录下，rabbitmq.4.dll 扔到 D:\phpStudy\php\php-7.1.20-nts目录下

2. 重启查看是否安装成功
第一次重启没反应，退出再次重启好了，PHPinfo看到amqp信息了

## 编写代码测试
productor.php
```php
<?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'; //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);

//创建交换机对象
$ex = new AMQPExchange($channel);
$ex->setName($e_name);
date_default_timezone_set("Asia/Shanghai");
//发送消息
//$channel->startTransaction(); //开始事务
for($i=0; $i<5; ++$i){
    sleep(1);//休眠1秒
    //消息内容
    $message = "TEST MESSAGE! $i ".date("h:i:sa");
    echo "Send Message:".$ex->publish($message, $k_route)."\n";
}
//$channel->commitTransaction(); //提交事务
$conn->disconnect();
?>
```

consumer.php
```php
<?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->declareExchange()."\n";

//创建队列
$q = new AMQPQueue($channel);
$q->setName($q_name);
$q->setFlags(AMQP_DURABLE); //持久化
echo "Message Total:".$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 "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
}
?>
```

先运行consumer.php，然后运行productor.php，看到效果了~

## 使用composer类库操作
官网文档：https://www.rabbitmq.com/tutorials/tutorial-one-php.html?_blank

### 1. 安装类库
`composer require php-amqplib/php-amqplib`
### 2. 编写测试代码
```php
<?php
namespace app\controller;
use PhpAmqpLib\Connection\AMQPStreamConnection;
use PhpAmqpLib\Message\AMQPMessage;
class RabbitController extends \app\controller\BaseController
{
	public function __construct(){
		$this->connection = new AMQPStreamConnection('localhost', 5672, 'admin', 'admin');
		$this->channel = $this->connection->channel();
	}
	public function productor(){

$this->channel->queue_declare('hello', false, false, false, false);

$msg = new AMQPMessage('Hello World!');
		$this->channel->basic_publish($msg, '', 'hello');

echo " [x] Sent 'Hello World!'\n";

$this->channel->close();
		$this->connection->close();
		exit();
	}
	public function consumer(){
		$this->channel->queue_declare('hello', false, false, false, false);
		echo " [*] Waiting for messages. To exit press CTRL+C\n";
		$callback = function ($msg) {
		    echo ' [x] Received ', $msg->body, "\n";
		};
		$this->channel->basic_consume('hello', '', false, true, false, false, $callback);
		while (count($this->channel->callbacks)) {
		    $this->channel->wait();
		}
		$this->channel->close();
		$this->connection->close();
		exit();
	}
}
```
### 3. 运行测试
效果如下图：
