axum-server-dual-protocol

Description

Provides utilities to host a axum-server server that accepts the HTTP and HTTPS protocol on the same port. See bind_dual_protocol().

A common use case for this is if a HTTPS server is hosted on a non-traditional port, having no corresponding HTTP port. This can be an issue for clients who try to connect over HTTP and get a connection reset error. See ServerExt::set_upgrade().

Usage

The simplest way to start is to use bind_dual_protocol():

let app = Router::new().route(
	"/",
	routing::get(|request: Request<Body>| async move {
		match request.extensions().get::<Protocol>().unwrap() {
			Protocol::Tls => "Hello, secure World!",
			Protocol::Plain => "Hello, insecure World!",
		}
	}),
);

// User-supplied certificate and private key.
let config = RustlsConfig::from_der(certificate, private_key).await?;

axum_server_dual_protocol::bind_dual_protocol(address, config)
	.serve(app.into_make_service())
	.await?;

We now have a server accepting both HTTP and HTTPS requests! Now we can automatically upgrade incoming HTTP requests to HTTPS using ServerExt::set_upgrade() like this:

use axum_server_dual_protocol::ServerExt;

axum_server_dual_protocol::bind_dual_protocol(address, config)
	.set_upgrade(true)
	.serve(app.into_make_service())
	.await?;

Alternatively UpgradeHttpLayer can be used:

let app = Router::new()
	.route("/", routing::get(|| async { "Hello, world!" }))
	.layer(UpgradeHttpLayer);

MSRV

As this library heavily relies on axum-server, axum, tower and hyper the MSRV depends on theirs. At the point of time this was written the highest MSRV was axum with 1.66.
