Force HTTPS

force-https 中間件可以強製所有的請求轉嚮至使用 HTTPS 協議.

此中間價如果應用於 Router 則隻有在路由匹配到時才會強製轉換協議，如果遇到頁麵不存在的情況，則不會轉嚮.

但更常見的需求是期望任何的請求都自動轉嚮，即使在路由未能匹配，返回 404 錯誤時，這時候可以把中間件添加到 Service 上. 不管請求是否被路由成功匹配， Service 上添加的中間件總是會執行.

示例代碼

use salvo::conn::rustls::{Keycert, RustlsConfig};
use salvo::prelude::*;

#[handler]
async fn hello() -> &'static str {
    "Hello World"
}

#[tokio::main]
async fn main() {
    tracing_subscriber::fmt().init();

    let router = Router::new().get(hello);
    let service = Service::new(router).hoop(ForceHttps::new().https_port(5443));

    let config = RustlsConfig::new(
        Keycert::new()
            .cert(include_bytes!("../certs/cert.pem").as_ref())
            .key(include_bytes!("../certs/key.pem").as_ref()),
    );
    let acceptor = TcpListener::new("0.0.0.0:5443")
        .rustls(config)
        .join(TcpListener::new("0.0.0.0:5800"))
        .bind()
        .await;
    Server::new(acceptor).serve(service).await;
}
