使用 Rust 中的 warp 框架同时在多个端口（http、https）上提供服务

Question

我想使用warp提供多个连接，以便我可以将每个 http 请求重定向到 https。这就是我现在要做的事情。

#[tokio::main]
async fn main() {

    let http_routes = warp::path("http").map(|| {
        println!("This is http server");
        warp::redirect(Uri::from_static("https://127.0.0.1:2443"))
    });

    let https_routes = warp::any().map(|| {
        println!("This is https server");
        "Hello, World! You are connected through tls connection."
    });

    let _http_warp = warp::serve(http_routes)
        .run(([127, 0, 0, 1], 2080)).await;

    let _https_warp = warp::serve(https_routes)
        .tls()
        .cert_path("sec/dmp.cert")
        .key_path("sec/dmp.key")
        .run(([127, 0, 0, 1], 2443)).await;
}

这不能按预期工作。它只侦听端口 2080，而不侦听 2443

我也尝试过 future::join

#[tokio::main]
async fn main() {

    ----snip----

    let (_http_addr, http_warp) = warp::serve(http_routes)
        .bind_ephemeral(([127, 0, 0, 1], 2080));

    let (_https_addr, https_warp) = warp::serve(https_routes)
        .tls()
        .cert_path("sec/dmp.cert")
        .key_path("sec/dmp.key")
        .bind_ephemeral(([127, 0, 0, 1], 2443));

    future::join(http_warp, https_warp).await?
}

这给出了错误

error[E0277]: the `?` operator can only be applied to values that implement `std::ops::Try`

运行这个完全是一件简单的事情，那就是删除？来自await 语句的后缀在末尾并放置一个分号。

future::join(http_wrap, https_wrap).await? // FROM THIS
future::join(http_wrap, https_wrap).await; // TO THIS

就是这样。现在，两个 future 同时运行，因此它会监听两个端口。
