该博客记录了RabbitMQ的安装、使用composer安装php - amqplib以及Tp5的实现过程，同时提供了相关学习地址，如cnblogs、csdn、segmentfault等平台的文章链接，不过仅作学习记录，不能直接运行。

注意：仅仅记录学习，不能直接运行，有任何问题请留言。

1. 安装RabbitMQ

拉取镜像

docker pull rabbitmq:3.7.7-management

docker run -d --name rabbitmq3.7.7 -p 5672:5672 -p 15672:15672 -v `pwd`/data:/var/lib/rabbitmq --hostname myRabbit -e RABBITMQ_DEFAULT_VHOST=my_vhost  -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin df80af9ca0c9

2. composer安装php-amqplib

composer require php-amqplib/php-amqplib

3.Tp5 实现

再次封装php-amqplib

<?php

namespace app\common\tool;
use app\common\config\SelfConfig;
use PhpAmqpLib\Connection\AMQPStreamConnection;

class RabbitMQTool {

    /**

     * Description:

    private $channel;

    private $mqConf;

    /**
     * RabbitMQTool constructor.
     * @param $mqName
     */
    public function __construct($mqName)
    {
        // 获取rabbitmq所有配置
        $rabbitMqConf = SelfConfig::getConfig('Source.rabbit_mq');
        if (!isset($rabbitMqConf['rabbit_mq_queue'])) {
            die('没有定义Source.rabbit_mq');
        }
        //建立生产者与mq之间的连接
        $this->conn = new AMQPStreamConnection(

        );
        $channal = $this->conn->channel();
        if (!isset($rabbitMqConf['rabbit_mq_queue'][$mqName])) {
            die('没有定义'.$mqName);
        }
        // 获取具体mq信息
        $mqConf = $rabbitMqConf['rabbit_mq_queue'][$mqName];
        $this->mqConf = $mqConf;
        // 声明初始化交换机
        $channal->exchange_declare($mqConf['exchange_name'], 'direct', false, true, false);
        // 声明初始化一条队列
        $channal->queue_declare($mqConf['queue_name'], false, true, false, false);
        // 交换机队列绑定
        $channal->queue_bind($mqConf['queue_name'], $mqConf['exchange_name']);
        $this->channel = $channal;
    }

    /**

     * @return RabbitMQTool
     * Description: 返回当前实例
     */
    public static function instance($mqName) {
        return new RabbitMQTool($mqName);
    }

    /**

     * @param $data
     * Description: 写mq
     * @return bool
     */
    public function wMq($data) {
        try {
            $data = json_encode($data, JSON_UNESCAPED_UNICODE);
            $msg = new AMQPMessage($data, ['content_type' => 'text/plain', 'delivery_mode' => 2]);
            $this->channel->basic_publish($msg, $this->mqConf['exchange_name']);
        } catch (\Throwable $e) {
            $this->closeConn();
            return false;
        }
        $this->closeConn();
        return true;
    }

    /**
     * User: yuzhao
     * @param int $num
     * @return array
     * Description:
     * @throws \ErrorException
     */
    public function rMq($num=1) {
        $rData = [];
        $callBack = function ($msg) use (&$rData){
            $rData[] = json_decode($msg->body, true);
        };
        for ($i=0;$i<$num;$i++) {
            $this->channel->basic_consume($this->mqConf['queue_name'], '', false, true, false, false, $callBack);
        }
        $this->channel->wait();
        $this->closeConn();
        return $rData;
    }

    /**
     * User: yuzhao
     * Description: 关闭连接
     */
    public function closeConn() {
        $this->channel->close();
        $this->conn->close();
    }

}

入队列

<?php

    public function test() {

    }

    }
