TCP/UDP 服务

框架默认提供创建 TCP/UDP 服务的能力。只需要进行简易的配置，便可使用。

使用 TCP 服务

创建 TcpServer 类

<?php
declare(strict_types=1);
namespace App\Controller;
use Hyperf\Contract\OnReceiveInterface;
class TcpServer implements OnReceiveInterface
{
    public function onReceive($server, int $fd, int $reactorId, string $data): void
    {
        $server->send($fd, 'recv:' . $data);
    }
}

创建对应配置

<?php
declare(strict_types=1);
use Hyperf\Server\Server;
use Hyperf\Server\Event;
return [
    // 以下删除了其他不相关的配置项
    'servers' => [
        [
            'name' => 'tcp',
            'type' => Server::SERVER_BASE,
            'host' => '0.0.0.0',
            'port' => 9504,
            'sock_type' => SWOOLE_SOCK_TCP,
            'callbacks' => [
                Event::ON_RECEIVE => [App\Controller\TcpServer::class, 'onReceive'],
            ],
            'settings' => [
                // 按需配置
            ],
        ],
    ],
];

实现客户端

<?php
$client = new \Swoole\Client(SWOOLE_SOCK_TCP);
$client->connect('127.0.0.1', 9504);
$client->send('Hello World.');
$ret = $client->recv(); // recv:Hello World.

使用 UDP 服务

创建 UdpServer 类

如果没有 OnPacketInterface 接口文件，则可以不实现此接口，运行结果与实现接口一致，只要保证配置正确即可。

<?php
declare(strict_types=1);
namespace App\Controller;
use Hyperf\Contract\OnPacketInterface;
class UdpServer implements OnPacketInterface
{
    public function onPacket($server, $data, $clientInfo): void
    {
        var_dump($clientInfo);
        $server->sendto($clientInfo['address'], $clientInfo['port'], 'Server：' . $data);
    }
}

创建对应配置

<?php
declare(strict_types=1);
use Hyperf\Server\Server;
use Hyperf\Server\Event;
return [
    // 以下删除了其他不相关的配置项
    'servers' => [
        [
            'name' => 'udp',
            'type' => Server::SERVER_BASE,
            'host' => '0.0.0.0',
            'port' => 9505,
            'sock_type' => SWOOLE_SOCK_UDP,
            'callbacks' => [
                Event::ON_PACKET => [App\Controller\UdpServer::class, 'onPacket'],
            ],
            'settings' => [
                // 按需配置
            ],
        ],
    ],
];
