Conditional Middleware

[MasteryOfMastering]

Is it possible to have conditional middleware prior to executing the main handler, something like request.next?

This seems to work.

Maybe add a section on the website under middleware as custom middleware?

async fn auth_middleware(depot: &mut Depot, res: &mut Response, ctrl: &mut FlowCtrl) {
    if let Some(session) = depot.session() {
        if let Some(id) = session.get::<i64>("id") {
            // do some processing here
           return;
        }
    }

    res.set_status_code(StatusCode::UNAUTHORIZED);
    ctrl.skip_rest();
}

This seems to be a relatively common functional requirement， so I added hoop_when, it will wrap the middleware, the middleware will executed when filter returns true.

This is excellent.

Nice work on the framework, slowly become my favourite one across all languages!

Hi @chrislearn

How can I implement Basic Auth or another middleware in my handler so that it is only applied when necessary, and the need for this authentication is determined dynamically within the request, for example, when retrieving information from the database?
