PHP使用MQ消息队列

2021-07-20 16:56:09 浏览数 (1)

1.安装php-amqplib 服务 在composer.json配置

代码语言：javascript复制
{
"require": {
"php-amqplib/php-amqplib": ">=2.6.1"
}
}

2.执行composer.phar install 来安装

3.引入mq文件

代码语言：javascript复制
define('EXTEND_PATH', '../vendor/autoload.php');
use appsynchronousmodelRabbitMqModel;
use PhpAmqpLibConnectionAMQPStreamConnection;

4.发送到队列数据代码

代码语言：javascript复制
/**
* MQ生产数据
* @param $queueName 队列名称
* @param $msg 发送数据
* @name MqPushLish
* @author 
* @return
*/
public function MqPublish($queueName , $msg = []){
try{
if(empty($queueName))
return false;
//获取mq配置
$mqConfig = $this->getConfig();
//创建连接和channel
$connection = new AMQPStreamConnection($mqConfig['host'] , $mqConfig['port'] , $mqConfig['user'] , $mqConfig['password']);
$channel = $connection->channel();
$name = $queueName;
$type = "direct";
$passive = false;
$durable = true;
$auto_delete = true;
$channel->exchange_declare($name, $type, $passive, $durable, $auto_delete);
$message = new AMQPMessage('[{"data_id":184981,"complex_id":7821,"area":"bj","dj":0,"mj":84,"shi":"2室","ting":"2厅","wei":"1卫","chu":"1厨","cate_status":"4","thumb":"https://img.yuanmabao.com/zijie/pic/2021/07/20/u3pqel5mxzx.png","tujis":["https://img.yuanmabao.com/zijie/pic/2021/07/20/u3pqel5mxzx.png"],"create_time":1512937831,"update_time":1533907683,"house_toward":"南北","reference_totalprice":0,"reference_down_payment":""},{"data_id":184981,"complex_id":9057,"area":"sh","dj":0,"mj":84,"shi":"2室","ting":"2厅","wei":"1卫","chu":"1厨","cate_status":"4","thumb":"https://img.yuanmabao.com/zijie/pic/2021/07/20/u3pqel5mxzx.png","tujis":["https://img.yuanmabao.com/zijie/pic/2021/07/20/u3pqel5mxzx.png"],"create_time":1512937831,"update_time":1533907683,"house_toward":"南北","reference_totalprice":0,"reference_down_payment":""}]');
$channel->basic_publish($message,'', $queueName);//发送数据到MQ
$channel->close();
$connection->close();
//打印日志
DeShangLog::log(0, $msg ,$queueName.'MQ发送队列数据正常');
return true;
}catch (Exception $e){
//打印日志
DeShangLog::log(1, $e->getMessage() ,'MQ发送队列数据异常！！！！！！！！！！！！！！！！');
return false;
}
}

5.消费队列数据代码

代码语言：javascript复制
/**
* MQ消费数据 监视数据
* @param $queueName 队列名称
* @name MqConsumer
* @author Admin
* @return
*/
public function mqConsumer(){
try{
$queueName = $this->getx('queue' , 'complex_info_test');
if(empty($queueName)){
echo "not queue ";die;
}
//创建连接和channel
$connection = new AMQPStreamConnection(C('config_mq.host') , C('config_mq.port') , C('config_mq.user') , C('config_mq.password'));
$channel = $connection->channel();
$channel->queue_declare($queueName, false, true, false, false);
echo ' [*] Waiting for messages. To exit press CTRL C', "n";
$callback = function($msg) {
//打印日志，记录消费的数据
DeShangLog::log(0, $msg->body ,'MQ接收户型同步数据');
$returnData = json_decode($msg->body , true);
//调用插入户型数据
$this->addDoorList($returnData);
echo " [x] Received ", $msg->body, "n";
};
$channel->basic_consume($queueName, '', false, false, false, false, $callback);//消费出数据
while(count($channel->callbacks)) {
$channel->wait();
}
$channel->close();
$connection->close();
}catch (Exception $e){
//打印日志
DeShangLog::log(1, $e->getMessage() ,'MQ发送队列数据异常！！！！！！！！！！！！！！！！');
return false;
}
}

6.在linux 配置守护进程

代码语言：javascript复制
 命令：``` nohup php index.php /synchronous/synchronous/mqconsumer & ``` “&” 代表不间断运行
    在/etc/rc.local文件中，将 ``` nohup php index.php /synchronous/synchronous/mqconsumer
 ```这个命令加入即可。
ps：注意路径
composer
