Hands-On Microservices with Rust

Signin

Other methods allow users to sign in to a microservice with the provided credentials. Look at the following signin function that processes requests that are sent to the /signin path:

fn signin((req, params): (HttpRequest<State>, Form<UserForm>))    -> FutureResponse<HttpResponse>{    let fut = post_request("http://127.0.0.1:8001/signin", params.into_inner())        .map(move |id: UserId| {            req.remember(id.id);            HttpResponse::build_from(&req)            .status(StatusCode::FOUND)            .header(header::LOCATION, "/comments.html")            .finish()        });    Box::new(fut)}

The function has two parameters: HttpRequest and Form. The first we need to get access to a shared State object. The second we need to extract the UserForm struct from the request body. We can also use the post_request ...
