hi @SamuelBonilla thank you very much, it works! My bad I've only tried into()
and forgetting about the into_response()
function.
I think this issue might be closed. Doo you think it might be useful to add this info in README/doc? If so, I might open a PR for that :)

@andreapavoni Sure, you can try with
use graphul::{Graphul, http::{response::Redirect, Methods}, Context };
#[tokio::main]
async fn main() {
let mut app = Graphul::new();
app.get("/", || async {
// Redirect::temporary(uri) Create a new Redirect that uses a 307 Temporary Redirect status code.
// Redirect::permanent(uri) Create a new Redirect that uses a 308 Permanent Redirect status code.
Redirect::to("/hi/samuel") // Create a new Redirect that uses a 303 See Other status code.
});
app.get("/hi/:name", |c: Context| async move {
format!("hello, {}", c.params("name"))
});
app.run("127.0.0.1:8000").await;
}

Thank you! It somewhat works, but I still have some problem in using it in practice. I need to check authentication when loading a page, if it's not authenticated, the user should be redirected on another page. I tried:
- inside the handler, I call the redirect if not authenticated, or render a template -> I get a compiler error:
expected struct `Redirect`, found struct `HtmlTemplate`
- using a middleware: redirect if not authenticated, or call
next.run(request).await
-> I a similar compiler error:
expected struct `http::response::Response`, found struct `Redirect`
I'm mostly a Rust beginner and maybe I'm just doing some silly mistake or overlooking some detail. I understand there's something about mismatching return types, but I've seen that in axum there should be some conversion into a compatible response object even if using a redirect (not sure about this, I've build 2 micro-apps with axum, but I've never needed redirects until now)

Hmm 🤔, Could you share some example code to try to reproduce the error?
from graphul.
@andreapavoni try with this example, you need to use .into_response
use graphul::{Graphul, http::{response::Redirect, Methods}, Context, IntoResponse };
#[tokio::main]
async fn main() {
let mut app = Graphul::new();
// http://127.0.0.1:8000?redirect=true
app.get("/", |c: Context| async move {
// Redirect::temporary(uri) Create a new Redirect that uses a 307 Temporary Redirect status code.
// Redirect::permanent(uri) Create a new Redirect that uses a 308 Permanent Redirect status code.
if c.query("redirect") == "true" {
return Redirect::to("/hi/samuel").into_response() ; // Create a new Redirect that uses a 303 See Other status code.
}
"index".into_response()
});
app.get("/hi/:name", |c: Context| async move {
format!("hello, {}", c.params("name"))
});
app.run("127.0.0.1:8000").await;
}
from graphul.
Sure, here's an example of my use case (the real code is really messed with other stuff as of now):
app.get("/", |_c: Context| async move {
let authenticated = false;
if !authenticated {
Redirect::to("/login")
} else {
let template = HomeTemplate {
message: "Hello".to_string(),
};
HtmlTemplate(template)
}
});
As you can see, I'm trying to redirect the user, rather than showing the template. The other case using a middleware is similar:
async fn check_user_is_authenticated(request: Req, next: Next) -> Response {
let authenticated = false;
if !authenticated {
return Redirect::to("/login");
} else {
next.run(request).await
}
}
The error is similar, in both cases the compiler complains about mismatching return types. Thank you for your help!

like my previous comment try with .into_reponse, this is an implementation for your example code
middleware
async fn check_user_is_authenticated(request: Req, next: Next) -> Response {
let authenticated = false;
if !authenticated {
return Redirect::to("/login").into_response() ;
} else {
next.run(request).await
}
}
Handler
app.get("/", |_c: Context| async move {
let authenticated = false;
if !authenticated {
Redirect::to("/login").into_response()
} else {
let template = HomeTemplate {
message: "Hello".to_string(),
};
HtmlTemplate(template).into_response()
}
});
