启动服务，我们就可以简单的使用 MQTT 服务了。

自定义事件

组件增加了可以监听 MQTT 服务各个阶段的事件，比如我们写一个 MQTTConnectHandler 用来监听客户端连接。

PUBLISH, SUBSCRIBE 和 UNSUBSCRIBE 三个事件，需要自行实现

<?php

declare(strict_types=1);

namespace App\MQTT\Event;

use Hyperf\HttpMessage\Server\Response;use Psr\Http\Message\ServerRequestInterface;use Zyimm\MqttServer\Annotation\MQTTConnect;use Zyimm\MqttServer\Handler\HandlerInterface;

#[MQTTConnect(priority: 1)]
class MQTTConnectHandler implements HandlerInterface
{
    public function handle(ServerRequestInterface $request, Response $response): Response
    {
        var_dump((string) $request->getBody());
        return $response;
    }
}

重启服务，连接 MQTT 时，便可以得到以下输出。

$ php bin/hyperf.php start
[INFO] TCP Server listening at 0.0.0.0:1883
string(234) "{"type":1,"protocol_name":"MQTT","protocol_level":4,"clean_session":1,"will":{"qos":0,"retain":0,"topic":"simps-mqtt\/user001\/delete","message":"byebye"},"user_name":"","password":"","keep_alive":10,"client_id":"Simps_60e5aa0c4284f"}"

组件支持的事件列表如下：

事件	备注
MQTTConnect	客户端连接时触发
MQTTDisconnect	客户端断开连接时触发
MQTTPingReq
MQTTPublish	客户端发布消息时触发
MQTTSubscribe	客户端订阅时触发
MQTTUnsubscribe	客户端取消订阅时触发

注解支持参数如下

参数	备注
server	指定当前事件对应的服务名
type	事件类型
priority	事件优先级，越大越先执行，默认的事件优先级为 0
