Currently using axum v0.6.20 and hyper v0.14.28 I have the following code that is work amazingly:

#[tokio::main]
async fn main() {
  let app = Router::new()
    .route("/", get(handler))
    .route("/custom/*key", get(proxy).post(proxy));

  // ...
}

pub async fn proxy(mut req: Request<Body>) -> Result<Response<Body>, StatusCode> {
  let path_query = req
    .uri()
    .path_and_query()
    .map_or_else(|| req.uri().path(), |v| v.as_str());

  let uri = format!("http://localhost:9000/{}", path_query);

  *req.uri_mut() = Uri::try_from(uri).unwrap();

  // This comes from State in real code
  let hyper_client = HyperClient::new();

  let res = hyper_client.request(req).await.unwrap();

  if res.status().is_server_error() {
    return Err(StatusCode::INTERNAL_SERVER_ERROR);
  }

  Ok(res)
}

Now with axum v0.7 (and hyper v1 without the Client anymore) I don't understand how to make it work with reqwest.

Can you point me in the right direction, please?

reqwest is still working on upgrading to hyper 1.0.

@seanmonstar what about reqwest 0.12 today? Can you hint me a way to accomplish this?
