我想使用 Hyper 来制作 HTTP 请求。调用Client::get
工作正常,但其他方法,如Client::post
和Client::head
导致编译错误。
extern crate futures;
extern crate hyper;
extern crate tokio_core;
use std::io::{self, Write};
use futures::{Future, Stream};
use hyper::Client;
use tokio_core::reactor::Core;
fn main() {
let mut core = Core::new().unwrap();
let client = Client::new(&core.handle());
let uri = "http://httpbin.org/ip".parse().unwrap();
let work = client.post(uri).and_then(|res| {
// if post changed to get it will work correctly
println!("Response: {}", res.status());
res.body("x=z")
.for_each(|chunk| io::stdout().write_all(&chunk).map_err(From::from))
});
core.run(work).unwrap();
}
错误:
