rust - 如何创建一个服务于 API 并使用 Iron 回退到磁盘的服务器？

Question

我尝试了以下方法:

let mut router = Router:new();
router.get("/hello",  |_: &mut Request| {
  Ok(Response::with((status::Ok, "hello")))
}, "/hello");

let mut mount = Mount::new();
mount.mount("/", router)
     .mount("/", Static::new(Path::new("src/public/")));

但是当我尝试访问 /hello 时，它会导致“没有这样的文件或目录”错误:

Request {
    url: Url { generic_url: "http://localhost:10800/hello" }
    method: Get
    remote_addr: V4(127.0.0.1:57260)
    local_addr: V4(127.0.0.1:10800)
}
Error was: Error { repr: Os { code: 2, message: "No such file or directory" } }

根本不需要使用Router；只需将处理程序直接传递给 mount:

extern crate iron;
extern crate mount;
extern crate staticfile;

use iron::prelude::*;
use iron::status;
use mount::Mount;
use staticfile::Static;

use std::path::Path;

fn main() {
    let hello = |_: &mut Request| {
        Ok(Response::with((status::Ok, "hello")))
    };

    let mut mount = Mount::new();
    mount.mount("/hello", hello)
        .mount("/", Static::new(Path::new("src/public/")));

    let _server = Iron::new(mount).http("localhost:3000").unwrap();
    println!("On 3000");
}

$ curl localhost:3000/animal
cow
$ curl localhost:3000/hello
hello
