Support MongoDBStore

[JustMangoou]

This PR adds MongoDB as an option for storing sessions.

closes #4

[maxcountryman]

Wonderful! Thank you for this.

[maxcountryman]

It looks like we'll want to run cargo +nightly fmt to pass CI.

[maxcountryman]

We're getting closer--it looks like the integration tests might not be passing.

[JustMangoou]

Yeah, I'm investigating why it does not work, it's been 1hr but still no progress

[maxcountryman]

Does it work for you locally?

I'm not too familiar with Mongo unfortunately, but I wonder if there could be some difference between the container's version of Mongo and a local version.

[JustMangoou]

Unfortunately, it doesn't work locally. My guess is that Deserializing Object from MongoDB to Rust SessionRecord maybe the cause

I'm not sure exactly how you're testing, but if you're using the HandleErrorLayer, you can bind BoxError to something like err and dbg!(err) to get a better idea of what's failing.

So something like this:

[tokio::main]
 async fn main() -> Result<(), Box<dyn std::error::Error>> {
     let database_url = std::option_env!("DATABASE_URL").expect("Missing DATABASE_URL.");
     let client = mongodb::Client::with_uri_str(database_url).await.unwrap();

     let session_store = MongoDBStore::new(client, "tower-sessions".to_string());
     let session_service = ServiceBuilder::new()
         .layer(HandleErrorLayer::new(|err: BoxError| async {
             dbg!(err);
             StatusCode::BAD_REQUEST
         }))
         .layer(
             SessionManagerLayer::new(session_store)
                 .with_secure(false)
                 .with_max_age(Duration::seconds(10)),
         );

     let app = Router::new()
         .route("/", get(handler))
         .layer(session_service);

     let addr = SocketAddr::from(([127, 0, 0, 1], 3000));
     axum::Server::bind(&addr)
         .serve(app.into_make_service())
         .await?;

     Ok(())
 }

Tests passed on local

[JustMangoou]

to_string() screwed up the deserialize step, not sure why but using Binary UUID fix it

[maxcountryman]

Being able to use the native type seems quite nice! This seems good to me.

[JustMangoou]

Also I noticed that sqlx providers don't use native uuid (binary), or maybe it needs to be stored as string? I'm not familiar with uuid in sql.

[maxcountryman]

At least with Postgres, there's a module you can enable to support UUID as a column type. But I'm not sure if it's available by default these days and so it's not something that's currently being used.
