Hello I wrote a web server with hyper. and I want to get the client IP that requested to the server. my code : async fn show_headers(req: Request<Body>) -> Result<Response<Body>, Infallible> { let ip = "test!"; let mut headers = format!( "{}\n{}\n\r{} {} {}\n", ip, …

The information is provided to the make_service_fn through the remote_addr method on the parameter on the closure, and you will have to pass the address further inside manually.

thanks but I'm a newbie in Rust could you please explain to how to do that?

If you're using hyper as a server, you probably have a make_service_fn somewhere in your code. Can you post that part?

Sure let make_service = make_service_fn(|_conn| async { Ok::<_, Infallible>(service_fn(show_headers)) }); let server = Server::bind(&addr).serve(make_service); Thanks

You'll want something like this: async fn show_headers(req: Request<Body>, addr: SocketAddr) -> Result<Response<Body>, Infallible> { ... } let make_service = make_service_fn(|conn| async { let addr = conn.remote_addr(); Ok::<_, Infallible>(service_fn(move |req| show_headers…

I did but There is an error :expressionless: error[E0282]: type annotations needed for `&Target` --> src/main.rs:49:50 | 49 | let make_service = make_service_fn(move |conn| { | ^^^^ consider giving this closure parameter the explicit…

Give this a try: use hyper::server::conn::AddrStream; let make_service = make_service_fn(|conn: AddrStream| async { let addr = conn.remote_addr(); Ok::<_, Infallible>(service_fn(move |req| show_headers(req, addr))) }); let server = Server::bind(&addr).serve(make_service); I…

didn't work :pensive: errors: error[E0631]: type mismatch in closure arguments --> src/main.rs:58:5 | 58 | make_service_fn(|conn: AddrStream| | _____^^^^^^^^^^^^^^^_- | | | | | expected signature of `for<'r> fn(&'r _) -> _` 59 | | async { 60 | | …

Ah right, that should be &AddrStream.

Yes right :slightly_smiling_face: :pray: but 1 error has occurred about lifetimes I tried to fix that but I do not have enough experience :pensive: code: let make_service = make_service_fn(|conn: &AddrStream|{ async { let addr=conn.remote_addr(); Ok::<_, Infall…

Ah, it should be async move.
