# WebSocket 服务
|
||
|
||
Hyperf 提供了对 WebSocket Server 的封装，可基于 [hyperf/websocket-server](https://github.com/hyperf-cloud/websocket-server) 组件快速搭建一个 WebSocket 应用。
|
||
|
||
## 安装
|
||
|
||
```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
|
||
|
||
> 目前暂时只支持配置文件的模式配置路由，后续会提供注解模式。
|
||
|
||
在 `config/routes.php` 文件内增加对应 `ws` 的 Server 的路由配置，这里的 `ws` 值取决于您在 `config/autoload/server.php` 内配置的 WebSocket Server 的 `name` 值。
|
||
|
||
```php
|
||
<?php
|
||
|
||
Router::addServer('ws', function () {
|
||
Router::get('/', 'App\Controller\WebSocketController');
|
||
});
|
||
```
|
||
|
||
## 创建对应控制器
|
||
|
||
```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;
|
||
|
||
class WebSocketController implements OnMessageInterface, OnOpenInterface, OnCloseInterface
|
||
{
|
||
public function onMessage(Server $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(Server $server, Request $request): void
|
||
{
|
||
$server->push($request->fd, 'Opened');
|
||
}
|
||
}
|
||
```
|
||
|
||
接下来启动 Server，便能看到对应启动了一个 WebSocket Server 并监听于 9502 端口，此时您便可以通过各种 WebSocket Client 来进行连接和进行数据传输了。
|
||
|
||
```
|
||
$ 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
|
||
```
