封装php的RabbitMq

Posted 2021-02-08 huangguowen

这段时间一直业务比较忙，因公司用的 databases 队列，用起来 感觉不是很爽，故简单封装了一个rabbitmq类（业务代码随便写的）

首先是账号密码配置

config.php

<?php
    return $arr = [
        ‘RabbitMq‘ => [
            // Rabbitmq 服务地址
            ‘host‘ => ‘127.0.0.1‘,
            // Rabbitmq 服务端口
            ‘port‘ => ‘5672‘,
            // Rabbitmq 帐号
            ‘login‘ => ‘guest‘,
            // Rabbitmq 密码
            ‘password‘ => ‘guest‘,
            ‘vhost‘=>‘/‘
        ]
    ];

基类 base.php 

<?php
include dirname(__FILE__).‘/object.php‘;
include dirname(__FILE__).‘/config.php‘;
class RabbitMq implements object
{
    //保存类实例的静态成员变量
    static private $_instance;
    static private $_conn;
    static private $amp ;
    static private $route = ‘key_1‘;
    static private $q ;
    static private $ex ;
    static private $queue;
    public static function getInstance(){
        global $arr;
        if (!(self::$_instance instanceof self)) {
            self::$_instance = new self($arr[‘RabbitMq‘]);
            return self::$_instance;
        }
        return self::$_instance;
    }

    private function __construct($conn)
    {
        //创建连接和channel
        $conn = new AMQPConnection($conn);
        if(!$conn->connect()) {
            die("Cannot connect to the broker!
");
        }
        self::$_conn = new AMQPChannel($conn);
        self::$amp = $conn;
    }
    /* *
     *
     * parm 交换机名
     * parm 队列名
     *
     * */
    public function listen($exchangeName,$queuename){
        self::$queue = $queuename;
        return $this->setExchange($exchangeName,$queuename);
    }

    //连接交换机
    public function setExchange($exchangeName,$queueName){
        //创建交换机
        $ex = new AMQPExchange(self::$_conn);
        self::$ex = $ex;
        $ex->setName($exchangeName);

        $ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型
        $ex->setFlags(AMQP_DURABLE); //持久化
        $ex->declare();
        return self::setQueue($queueName,$exchangeName);
    }

    //创建队列
    private static function setQueue($queueName,$exchangeName){
    //  创建队列
        $q = new AMQPQueue(self::$_conn);
        $q->setName($queueName);
        $q->setFlags(AMQP_DURABLE);
        $q->declareQueue();

    // 用于绑定队列和交换机
        $routingKey = self::$route;
        $q->bind($exchangeName,  $routingKey);
        self::$q = $q;
        return(self::$_instance);
    }

    /*
 * 消费者
 * $fun_name = array($classobj,$function) or function name string
 * $autoack 是否自动应答
 *
 * function processMessage($envelope, $queue) {
        $msg = $envelope->getBody();
        echo $msg."
"; //处理消息
        $queue->ack($envelope->getDeliveryTag());//手动应答
    }
 */
    public function run($func, $autoack = True){
        if (!$func || !self::$q) return False;
        while(True){
            if ($autoack) {
                if(!self::$q->consume($func, AMQP_AUTOACK)){
//                    self::$q->ack($envelope->getDeliveryTag());
                    echo 123;
                }
            }
             self::$q->consume($func);
        }
    }


    private static function closeConn(){
        self::$amp->disconnect();
    }

    public function pushlish($msg){
        while (1) {
            sleep(1);
            if (self::$ex->publish(date(‘H:i:s‘) . "用户" . "注册", self::$route)) {
                //写入文件等操作
                echo $msg;
            }
        }
    }

    //__clone方法防止对象被复制克隆
    public function __clone()
    {
        trigger_error(‘Clone is not allow!‘, E_USER_ERROR);
    }

}

consume 监听类（一个操作对应一个class）

<?php
include dirname(__FILE__).‘/base.php‘;
class Add
{
    public static function run(){

        $dbms=‘mysql‘;     //数据库类型
        $host=‘127.0.01‘; //数据库主机名
        $dbName=‘test‘;    //使用的数据库
        $user=‘root‘;      //数据库连接用户名
        $pass=‘admin‘;          //对应的密码
        $dsn="$dbms:host=$host;dbname=$dbName";

        sleep(1);
        try {
            $dbh = new PDO($dsn, $user, $pass); //初始化一个PDO对象
            /*你还可以进行一次搜索操作
            foreach ($dbh->query(‘SELECT * from FOO‘) as $row) {
                print_r($row); //你可以用 echo($GLOBAL); 来看到这些值
            }
            */
            $dbh = null;
        } catch (PDOException $e) {
            die ("Error!: " . $e->getMessage() . "<br/>");
        }
//默认这个不是长连接，如果需要数据库长连接，需要最后加一个参数：array(PDO::ATTR_PERSISTENT => true) 变成这样：
        $db = new PDO($dsn, $user, $pass, array(PDO::ATTR_PERSISTENT => true));
        $sql = ‘INSERT INTO `test`.`t_reg`(`names`) VALUES (9)‘;
        $row = $db->query($sql);
        if(!$row){
           return false;
        }
            echo ‘OK‘;
    }

}
$consume = new Add();
//tudo
//$s = RabbitMq::getInstance()->listen(‘jiaohuanji‘,‘queue1‘)->run(array($consume,‘run‘)); 将run函数带入到consume里面作为回调 在consume里面增加$funname ,增加代码粘性
$s = RabbitMq::getInstance()->listen(‘jiaohuanji‘,‘queue1‘)->run(array($consume,‘run‘));

push 类（发送者）

<?php
include "base.php";

RabbitMq::getInstance()->listen(‘jiaohuanji‘,‘queue1‘)->pushlish(‘请求已发送‘);

接口interface 

<?php
    interface object
    {
        public static function getInstance();
    }

监听 add.php

执行 send.php 即可完成简单的rabit操作
