Force HTTPS

force-https 中间件可以强制所有的请求转向至使用 HTTPS 协议.

此中间价如果应用于 Router 则只有在路由匹配到时才会强制转换协议，如果遇到页面不存在的情况，则不会转向.

但更常见的需求是期望任何的请求都自动转向，即使在路由未能匹配，返回 404 错误时，这时候可以把中间件添加到 Service 上. 不管请求是否被路由成功匹配， Service 上添加的中间件总是会执行.

示例代码

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;
}
