消息中间件之RabbitMQ thinkphp5.1用法

composer 安装

composer require php-amqplib/php-amqplib

代码如下

// +----------------------------------------------------------------------

namespace app\system\admin;


use PhpAmqpLib\Connection\AMQPStreamConnection;

    }


    function process_message($message)

    public function write_log($data='str:',$status=1){
        switch ($status){
            case 1 :
                $type = 'waning';
                break;
            case 2 :

                $type = 'note';
                break;
        }
        \think\facade\Log::write('End '.$data.'&status='.$status.''.'&=',$type);

    }
}

执行效果 给生产者发送数据

 

消费者接受数据
