Hi @biluohc

If your script run on Cloudflare Workers, you can get it by x-real-ip Request header.

app.get('/', (c) => {
  console.log(c.req.header('x-real-ip'))
  return c.text('foo')
})

On Deno and Bun, we don't have any way to get the client remote address.

Thanks.

The second parameter of the Handler is ConnInfo in the the standard library of Deno, consider supporting it?

Solved.

export function sa(da: Deno.Addr) {
  if (["tcp", "udp"].includes(da.transport)) {
    const a = (da as Deno.NetAddr);
    return `${a.hostname}:${a.port}`;
  } else {
    const a = (da as Deno.UnixAddr);
    return a.path;
  }
}

serve(async (request: Request, ci: ConnInfo) => {
  const env = { sa: sa(ci.remoteAddr) };
  return app.fetch(request, env)
})
