# WebSocket 服務
Hyperf 提供了對 WebSocket Server 的封裝,可基於 [hyperf/websocket-server](https://github.com/hyperf/websocket-server) 組件快速搭建一個 WebSocket 應用。
## 安裝
```bash
composer require hyperf/websocket-server
```
## 配置 Server
修改 `config/autoload/server.php`,增加以下配置。
```php
<?php
'servers' => [
[
'name' => 'ws',
'type' => Server::SERVER_WEBSOCKET,
'host' => '0.0.0.0',
'port' => 9502,
'sock_type' => SWOOLE_SOCK_TCP,
'callbacks' => [
SwooleEvent::ON_HAND_SHAKE => [Hyperf\WebSocketServer\Server::class, 'onHandShake'],
SwooleEvent::ON_MESSAGE => [Hyperf\WebSocketServer\Server::class, 'onMessage'],
SwooleEvent::ON_CLOSE => [Hyperf\WebSocketServer\Server::class, 'onClose'],
],
],
],
```
## 配置路由
> 目前暫時只支持配置文件的模式配置路由,後續會提供註解模式。
`config/routes.php` 文件內增加對應 `ws` 的 Server 的路由配置,這裏的 `ws` 值取決於您在 `config/autoload/server.php` 內配置的 WebSocket Server 的 `name` 值。
```php
<?php
Router::addServer('ws', function () {
Router::get('/', 'App\Controller\WebSocketController');
});
```
## 創建對應控制器
```php
<?php
declare(strict_types=1);
namespace App\Controller;
use Hyperf\Contract\OnCloseInterface;
use Hyperf\Contract\OnMessageInterface;
use Hyperf\Contract\OnOpenInterface;
use Swoole\Http\Request;
use Swoole\Server;
use Swoole\Websocket\Frame;
use Swoole\WebSocket\Server as WebSocketServer;
class WebSocketController implements OnMessageInterface, OnOpenInterface, OnCloseInterface
{
public function onMessage(WebSocketServer $server, Frame $frame): void
{
$server->push($frame->fd, 'Recv: ' . $frame->data);
}
public function onClose(Server $server, int $fd, int $reactorId): void
{
var_dump('closed');
}
public function onOpen(WebSocketServer $server, Request $request): void
{
$server->push($request->fd, 'Opened');
}
}
```
接下來啟動 Server便能看到對應啟動了一個 WebSocket Server 並監聽於 9502 端口,此時您便可以通過各種 WebSocket Client 來進行連接和進行數據傳輸了。
```
$ php bin/hyperf.php start
[INFO] Worker#0 started.
[INFO] WebSocket Server listening at 0.0.0.0:9502
[INFO] HTTP Server listening at 0.0.0.0:9501
```
