httpUpgrade issue

[mmmray]

what is the code for the worker? cloudflare workers is not part of the example.

[Fangliding]

try do delete ?ed=2560 in path

[X-Oracle]

try do delete ?ed=2560 in path

I tested both.
same result.

I logged the headers my server receives from Cloudflare worker network:

Headers from normal WebSocket:

host: SUBDOMAIN.EXAMPLE.COM
connection: Upgrade
upgrade: websocket
accept-encoding: gzip
x-forwarded-for: ***.***.***.***
cf-ray: **********************

PS: my connection scheme is like this:

CLient(xray v1.8.10) ---(Vless httpUpgrade (WITH TLS))----> CF-Worker ----(reroute vless through fetch() (NO TLS))----> nginx ---> xray v1.8.10

the issue lies in the communication between the Cloudflare Worker and your server.
example of how you can modify the headers in your Cloudflare Worker:

 addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request));
});

async function handleRequest(request) {
  const url = new URL(request.url);
  const path = url.pathname;
  const targetUrl = 'https://your-server.com' + path;

  const newRequest = new Request(targetUrl, {
    method: request.method,
    headers: request.headers,
    body: request.body,
    redirect: 'manual',
  });

  newRequest.headers.set('Upgrade', 'websocket');
  newRequest.headers.set('Connection', 'Upgrade');

  const response = await fetch(newRequest);
  return response;
}

如果 worker 的代码是解析并重新封装成 WebSocket，则无法支持 HTTPUpgrade
