ThinkPHP的AMQP库(支持RabbitMQ)

1.安装依赖库

composer require php-amqplib/php-amqplib
地址:https://github.com/php-amqplib/php-amqplib

2. mq生产者.php

include(__DIR__ . '../../public/config.php');
use PhpAmqpLib\Connection\AMQPStreamConnection;
use PhpAmqpLib\Message\AMQPMessage;
/**
 * Created by PhpStorm.
 * User: pandeng
 * Date: 2017-07-26
 * Time: 21:51
 */
class MessageQueue
{
    const exchange = 'router';
    const queue = 'msgs';
    public static  function pushMessage($data)
    {
        $connection = new AMQPStreamConnection(HOST, PORT, USER, PASS, VHOST);
        $channel = $connection->channel();

        $channel->queue_declare(self::queue, false, true, false, false);
        $channel->exchange_declare(self::exchange, 'direct', false, true, false);
        $channel->queue_bind(self::queue, self::exchange);
        $messageBody = $data;
        $message = new AMQPMessage($messageBody, array('content_type' => 'text/plain', 'delivery_mode' => AMQPMessage::DELIVERY_MODE_PERSISTENT));
        $channel->basic_publish($message, self::exchange);
        $channel->close();
        $connection->close();
        return "ok";
    }
}

3.消费者.php

namespace app\index\controller;
include(__DIR__ . '../../../../public/config.php');
use PhpAmqpLib\Connection\AMQPStreamConnection;

use think\Controller;
use think\Log;
use think\Request;
use think\Db;

class MessageConsume extends Controller
{
    const exchange = 'router';
    const queue = 'msgs';
    const consumerTag = 'consumer';

    function shutdown($channel, $connection)
    {
        $channel->close();
        $connection->close();
        write_log("closed",3);
    }

    function process_message($message)
    {
        if ($message->body !== 'quit') {
            $obj = json_decode($message->body);
            if (!isset($obj->id)) {
                echo 'error data\n';
                write_log("error data:" . $message->body, 2);
            } else {
                try {
                    write_log("data:" . json_encode($message));
                } catch (\Think\Exception  $e) {
                    write_log($e->getMessage(), 2);
                    write_log(json_encode($message), 2);
                } catch (\PDOException $pe) {
                    write_log($pe->getMessage(), 2);
                    write_log(json_encode($message), 2);
                }
            }
        }
        $message->delivery_info['channel']->basic_ack($message->delivery_info['delivery_tag']);
        // Send a message with the string "quit" to cancel the consumer.
        if ($message->body === 'quit') {
            $message->delivery_info['channel']->basic_cancel($message->delivery_info['consumer_tag']);
        }
    }

    /**
     * 启动
     *
     * @return \think\Response
     */
    public function start()
    {
        $connection = new AMQPStreamConnection(HOST, PORT, USER, PASS, VHOST);
        $channel = $connection->channel();
        $channel->queue_declare(self::queue, false, true, false, false);
        $channel->exchange_declare(self::exchange, 'direct', false, true, false);
        $channel->queue_bind(self::queue, self::exchange);
        $channel->basic_consume(self::queue, self::consumerTag, false, false, false, false, array($this, 'process_message'));

        register_shutdown_function(array($this, 'shutdown'), $channel, $connection);
        while (count($channel->callbacks)) {
            $channel->wait();
        }
        write_log("starting",3);
    }

}

4. 启动消费者（守护进程）

nohup php index.php index/Message_Consume/start &
