Setting a layer or service

[AppyCat]

Hi, how is can you set the redis store as a layer or service in the main function so the connection can be used in handlers?

Can you provide more context for this question? What framework are you using?

Yes, I am using Axum web framework.

I'm trying to use encrypted session cookies stored in Redis.

I read the docs, but don't see a way to add the Redis connection as a layer in Axum. I do see how to add the session as a session_layer.

The use case is to store a users id in an encrypted cookie with Redis as the session store.

Currently a record inserted in Redis in one handler cannot be retrieved in another handler.

Here's my setup:

use axum_sessions::{async_session::{Session, SessionStore as _}, SameSite, SessionLayer};
use async_redis_session::RedisSessionStore;

let secret = b"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
let session_layer = SessionLayer::new(store.unwrap(), secret)
.with_cookie_name("test-cookie")
.with_cookie_path("/")
.with_cookie_domain("www.test-cookie.com")
.with_same_site_policy(SameSite::None)
.with_session_ttl(Some(Duration::from_secs(60 * 5)))
.with_save_unchanged(true)
.with_secure(false);

I think this is an issue for the Axum sessions library, if I understand correctly

Thanks, I put a note out to them.

However am also getting the following errors on methods not existing in store from async-redis-session:

92 | let cookie_value = store.store_session(session).await;
| ^^^^^^^^^^^^^ method not found in Result<RedisSessionStore, redis::types::RedisError>

error[E0599]: no method named load_session found for enum Result in the current scope
--> src/main.rs:93:29
|
93 | let mut session = store.load_session("test-cookie".parse().unwrap()).await.unwrap();
| ^^^^^^^^^^^^ method not found in Result<RedisSessionStore, redis::types::RedisError>

Code is:

async fn do_something(Extension(session): Extension<Session>) -> Json<Value> {
    let store = RedisSessionStore::new("redis://127.0.0.1/");
    let cookie_value = store.store_session(session).await;
    let mut session = store.load_session("test-cookie".parse().unwrap()).await.unwrap();

    let user_id: String = session.get::<String>("user_id").unwrap();
    Json(json!({ "data": user_id }))
}

store is a Result that needs to be unwrapped or the error needs to be handled. Regardless, this is an issue for the axum session library.
