如果可能`actix-web`自动升级到*HTTP/2.0*的连接。
|

# 协议
|
||
|
||
*HTTP/2.0* protocol over tls without prior knowledge requires [tls alpn](https://tools.ietf.org/html/rfc7301).
|
||
|
||
> 目前，只有`rust-openssl`支持
|
||
|
||
`alpn`协议需要启用该功能。启用后，HttpServer提供 serve_tls方法。
|
||
[serve_tls](https://actix.rs/actix-web/actix_web/server/struct.HttpServer.html#method.serve_tls) method.
|
||
|
||
```toml
|
||
[dependencies]
|
||
actix-web = { version = "{{< actix-version "actix-web" >}}", features = ["alpn"] }
|
||
openssl = { version = "0.10", features = ["v110"] }
|
||
```
|
||
|
||
```rust
|
||
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();
|
||
}
|
||
```
|
||
|
||
不支持升级到[rfc section 3.2](https://http2.github.io/http2-spec/#rfc.section.3.2) 节中描述的HTTP/2.0模式 。明文连接和tls连接都支持*HTTP/2* with prior knowledge启动,[rfc section 3.4](https://http2.github.io/http2-spec/#rfc.section.3.4)
