我想使用Hyper的当前主分支编写服务器,该分支保存由POST请求传递的消息,并将此消息发送到每个传入的GET请求.

我有这个,大多是从Hyper示例目录中复制的:

extern crate futures;

extern crate pretty_env_logger;

use futures::future::FutureResult;

use hyper::{Get, Post, StatusCode};
use hyper::header::{ContentLength};
use hyper::server::{Http, Service, Request, Response};
use futures::Stream;

struct Echo {
    data: Vec<u8>,
}

impl Echo {
    fn new() -> Self {
        Echo {
            data: "text".into(),
        }
    }
}

impl Service for Echo {
    type Request = Request;
    type Response = Response;
    type Error = hyper::Error;
    type Future = FutureResult<Response, hyper::Error>;

    fn call(&self, req: Self::Request) -> Self::Future {
        let resp = match …
