前言:
有些人为了让项目快速上线,服务器往往安装宝塔面板,然后再极速安装LNMP。尽管环境搭建的时间省了,但是宝塔上PHP中扩展包没有提供AMQP。这时候只是为了使用消息队列而对PHP大动干戈, 不如使用一个PHP AMQP的库,即用即装,不对环境造成影响。
简介:
php-amqplib 客户端库,通过composer安装,不需要在PHP中安装扩展,以下为两种不同的安装方式。
- 项目中新建composer.json,添加如下代码,然后composer install
{
"require": {
"php-amqplib/php-amqplib": " 2.6.*"
}
}
- 命令进入到项目,然后 composer require php-amqplib/php-amqplib 2.6.*
RabbitMQ设置:
- 进入web管控台,添加新用户,角色管理员,任何IP上都可以登录,授权指定虚拟机。
- 添加交换机
- 添加队列并与交互机绑定。
编码:
1. 封装rabbitMQ类。
<?php
use PhpAmqpLib\Connection\AMQPStreamConnection;
use PhpAmqpLib\Message\AMQPMessage;
/**
* Class RabbitMQ.
*/
class RabbitMQ
{
const READ_LINE_NUMBER = 0;
const READ_LENGTH = 1;
const READ_DATA = 2;
public $config;
public static $prefix = 'autoinc_key:';

/**

*/
protected $channel;
protected $queue;
//配置项
private $host;
private $port;
private $user;
private $pass;
private $vhost;
public function __construct($config = [])
{
//$this->config = $config;
//设置rabbitmq配置值
$this->host = '192.168.1.101';
$this->port = 5672;
$this->user = 'beiqiaosu';

$reConnect = false;
while (1) {
try {
$this->initChannel();
$result = call_user_func_array([$this->channel, $method], $args);
} catch (\Exception $e) {
//已重连过,仍然报错
if ($reConnect) {
throw $e;
}
\Swoole::$php->log->error(__CLASS__ . ' [' . posix_getpid() . "] Swoole RabbitMQ[{$this->config['host']}:{$this->config['port']}] Exception(Msg=" . $e->getMessage() . ', Code=' . $e->getCode() . "), RabbitMQ->{$method}, Params=" . var_export($args, 1));
if ($this->connection) {
$this->close();
}
$this->connect();
$reConnect = true;
continue;
}
return $result;
}
//不可能到这里
return false;
}
/**
* 连接rabbitmq消息队列.
*
* @return bool
*/
public function connect()
{
try {
if ($this->connection) {
unset($this->connection);
}
$this->connection = new AMQPStreamConnection($this->host, $this->port, $this->user, $this->pass, $this->vhost);
} catch (\Exception $e) {
echo __CLASS__ ."Swoole RabbitMQ Exception'".$e->getMessage();
return false;
}
}
/**
* 关闭连接.
*/
public function close()
{
$this->channel->close();
$this->connection->close();
}
/**
* 设置交换机名称.
*
* @param string $exchangeName
*/
public function setExchangeName($exchangeName = '')
{
$exchangeName && $this->exchangeName = $exchangeName;
}
/**
* 设置队列名称.
*
* @param string $queueName
*/
public function setQueueName($queueName = '')
{
$queueName && $this->queueName = $queueName;
}
/**

*/
public function initChannel()
{
if (!$this->channel) {
//通道
$this->channel = $this->connection->channel();
$this->channel->queue_declare($this->queueName, false, true, false, false);
$this->channel->exchange_declare($this->exchangeName, 'direct', false, true, false);
$this->channel->queue_bind($this->queueName, $this->exchangeName);
}
}
/**

*/
public function pop()

try {

$message = $this->channel->basic_get($this->queueName);
if ($message) {
$this->channel->basic_ack($message->delivery_info['delivery_tag']);
$result = $message->body;
} else {
throw new \Exception('Empty Queue Data');
}
} catch (\Exception $e) {
//\Swoole::$php->log->error(__CLASS__ . " [" . posix_getpid() . "] Swoole RabbitMQ[{$this->config['host']}:{$this->config['port']}] Exception(Msg=" . $e->getMessage() . ", Code=" . $e->getCode() . ")");
sleep(1);
continue;
}
return $result;
}
//不可能到这里
return false;
}
/**

*
* @param $data
*
* @return bool
*/
public function push($data)
{
while (1) {
try {
$this->connect();
$this->initChannel();
$message = new AMQPMessage($data, ['content_type'=>'text/plain', 'devlivery_mode' => AMQPMessage::DELIVERY_MODE_PERSISTENT]);
$this->channel->basic_publish($message, $this->exchangeName);
} catch (\Exception $e) {
echo "$e->getMessage()";
continue;
}
return true;
}
//不可能到这里
return false;
}
}
2. 操作mq,出队,入队。
<?php
require_once "vendor/autoload.php";
require_once "component/RabbitMQ.php";
$mq = new RabbitMQ();
// 消息消费测试
/*try {
$res = $mq->pop();
}catch(\Exception $e) {
var_dump($e->getMessage());die;
}*/
// 消息生产测试
try {
$res = $mq->push(json_encode(['name'=>'beiqiaosu','order_id'=>'2020070115261425155']));
}catch(\Exception $e) {
var_dump($e->getMessage());die;
}
var_dump($res);die;
测试:
- 先通过生产消息(入队)方法运行一下,然后进入队列中get message查看消息总数。
- 测试调用消费,再查看总数。
