how to set upgrade by vite serve

[enmotion]

In my project, I need to automatically upgrade my HTTP or HTTPS requests to WebSocket (WS) or Secure WebSocket (WSS) requests, something I can easily configure in Nginx. However, in vite.config.ts, how can I achieve the same using server.proxy?
just like down below in nginx

location /my-websocket-app/ { proxy_pass http://localhost:3000; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; }

我在项目中，将需要使用到 nginx 配置中的 upgrade 设置，将我的 http或 https 请求自动升为 ws 或 wss 请求，在 nginx 中我能正常配置，但是在 vite.config.ts 中，我如何通过 server.proxy 的方式配置呢？

就像上方展示的在 nginx 中配置的情况！
