hyperf中如何使用Swoole\Table

本篇文章给大家分享的是有关hyperf中如何使用Swoole\Table，小编觉得挺实用的，因此分享给大家学习，希望大家阅读完这篇文章后可以有所收获，话不多说，跟着小编一起来看看吧。

Swoole\Table的create需要在workStart之前，所以tcp服务启动之前，在server.php中配置SwooleEvent::ON_BEFORE_START监听事件

        [
            'name' => 'tcp',
            'type' => Server::SERVER_BASE,
            'host' => '0.0.0.0',
            'port' => 9503,
            'sock_type' => SWOOLE_SOCK_TCP,
            'callbacks' => [
                SwooleEvent::ON_BEFORE_START => [\App\Tcp\ServerStartCallback::class, 'beforeStart'],
                SwooleEvent::ON_WORKER_START => [\App\Tcp\TcpServer::class, 'onWorkerStart'],
                SwooleEvent::ON_CONNECT => [\App\Tcp\TcpServer::class, 'onConnect'],
                SwooleEvent::ON_RECEIVE => [\App\Tcp\TcpServer::class, 'onReceive'],
            ]
        ]

在ServerStartCallback中实现Swoole\Table的初始化

<?php

namespace App\Tcp;

use Hyperf\Server\ServerInterface;
use Hyperf\Server\SwooleServerFactory;
use Hyperf\Utils\ApplicationContext;
use Swoole\Server;
use Swoole\Table;

class ServerStartCallback extends \Hyperf\Framework\Bootstrap\ServerStartCallback
{


    public function beforeStart()
    {
        $table = new Table(65536);
        $table->column('fd', Table::TYPE_INT);
        $table->column('reactor_id', Table::TYPE_INT);
        $table->column('data', Table::TYPE_STRING, 64);
        $table->create();
        $container = ApplicationContext::getContainer();
        $server = $container->get(Server::class);
        $server->table = $table;
    }
}

在TCP建立连接接收消息的时候，进行fd的绑定

<?php
declare(strict_types = 1);

namespace App\Tcp;

use Hyperf\Contract\OnOpenInterface;
use Hyperf\Contract\OnReceiveInterface;
use Hyperf\Logger\LoggerFactory;
use Hyperf\Server\ServerFactory;
use Hyperf\Di\Annotation\Inject;
use PBurggraf\CRC\CRC16\CRC16;
use Psr\Log\LoggerInterface;
use Swoole\Http\Request;
use Swoole\Server as SwooleServer;
use Swoole\Table;
use Swoole\WebSocket\Server;
use Hyperf\Framework\Logger\StdoutLogger;

class TcpServer implements OnReceiveInterface
{
    /**
     * @Inject
     * @var CRC16
     */
    private $crc16;

    /**
     * @var LoggerInterface
     */
    protected $logger;

    public function __construct(LoggerFactory $loggerFactory)
    {
        $this->logger = $loggerFactory->get('log', 'default');
    }

    public function onWorkerStart(SwooleServer $server, int $worker_id): void
    {

    }

    public function onConnect(SwooleServer $server, int $fd, int $fromId): void
    {
        $this->logger->debug($fd);
    }

    public function onReceive(SwooleServer $server, int $fd, int $fromId, string $data): void
    {
        $this->logger->debug($fd . ' - ' . $data);
        // 检测数据，如果返回的前4位字符为IMEI，则应该为设备绑定fd
        if (strpos($data, 'IMEI') === 0) {
            $imei = substr($data, 5);
            $server->table->set((string)$fd, [
                'reactor_id' => $fromId,
                'fd' => $fd,
                'data' => $imei
            ]);
        }
        $this->logger->debug($server->table->count());
    }

}
