actix-web
automatically upgrades connections to HTTP/2.0 if possible.
Negotiation
HTTP/2.0 protocol over tls without prior knowledge requires tls alpn.
Currently, only
rust-openssl
has support.
alpn
negotiation requires enabling the feature. When enabled, HttpServer
provides the
serve_tls method.
[dependencies]
actix-web = { version = "{{< actix-version "actix-web" >}}", features = ["alpn"] }
openssl = { version = "0.10", features = ["v110"] }
use std::fs::File;
use actix_web::*;
use openssl::ssl::{SslMethod, SslAcceptor, SslFiletype};
fn main() {
// load ssl keys
let mut builder = SslAcceptor::mozilla_intermediate(SslMethod::tls()).unwrap();
builder.set_private_key_file("key.pem", SslFiletype::PEM).unwrap();
builder.set_certificate_chain_file("cert.pem").unwrap();
HttpServer::new(
|| App::new()
.resource("/index.html", |r| r.f(index)))
.bind("127.0.0.1:8080").unwrap();
.serve_ssl(builder).unwrap();
}
Upgrades to HTTP/2.0 schema described in rfc section 3.2 is not supported. Starting HTTP/2 with prior knowledge is supported for both clear text connection and tls connection. rfc section 3.4
Check out examples/tls for a concrete example.
