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

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

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());    }}
