Why axum middleware does not work with "/" route ?

[HosMercury]

Summary

I have this router

pub fn router() -> Router<AppState> {
    Router::new().route("/", get(dashboard)).route("/t", get(t))
}

These is the combined routes

    let app = dashboard::router()
        .layer(middleware::from_fn(middlewares::auth_middlware))
        .merge(auth::router())
        .merge(oauth::router())
        .layer(session_layer)
        .with_state(state)
        .nest_service("/assets", ServeDir::new("assets"));

while this middleware is not working with the "/" route specifically while working with the test route "/t"

pub async fn auth_middlware(session: Session, request: Request, next: Next) -> Response {
    println!("middlware request");

    let user = session.get::<User>(USER_SESSION_KEY).await.unwrap();

    println!("user session {:#?}", user);

    if user.is_none() {
        println!("if user session {:?}", user);
        return Redirect::permanent("/login").into_response();
    }

    let response = next.run(request).await;

    response
}

what could be the reason?

axum version

latest

Middleware only apply to routes already added. So add all your routes first, then add middleware..

[HosMercury]

what do u mean by add all your routes first?

i want the middleware for specific routes

[davidpdrsn]

Ah sorry I misread your code. Regardless middleware does work on “/“ so must be something else the rejects the request.

Have you tried simplifying your code until works? Perhaps try removing the Session extractor.

i did

pub async fn auth_middlware(
    // session: Session,
    request: Request,
    next: Next,
) -> Response {
    println!("middlware request");

    // let user = session.get::<User>(USER_SESSION_KEY).await.unwrap();

    // println!("user session {:#?}", user);

    // if user.is_none() {
    //     println!("if user session {:?}", user);
    //     return Redirect::permanent("/login").into_response();
    // }

    let response = next.run(request).await;

    response
}

no println

the weird thing is
the page is redirected
although I have commented the code !!

this is the handler for / route

// #[axum::debug_handler]
pub async fn dashboard() -> DashboardTemplate {
    DashboardTemplate {
        title: "Dashboard",
        messages: None,
        username: "Hos".to_string(),
    }
}

i guess i found the issue
it is the redirection after AUTH

thanks Dav
