我正在搞乱reqwest库，想尝试一些Rust Playground的例子。我从网上获取了最简单的示例之一，但它无法编译。

请点击下面的链接，然后单击运行：

https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=fb0e7911a018ddb927cb13debd34fff4

这是控制台中显示的编译错误：

error: aborting due to previous error

error: could not compile `playground`

To learn more, run the command again with --verbose.

另一方面，当我在本地机器（Windows 10）上尝试相同的代码时，它会编译但会出现此错误：

D:\DANI\rust\projects\httpget>cargo run    Compiling httpget v0.1.0 (D:\DANI\rust\projects\httpget)

我检查了 Cargo.toml 中的依赖项：

[dependencies]
error-chain = "0.12.4"
reqwest = { version = "0.10" }
tokio = { version = "1", features = ["full"] }
futures = "0.3"

我认为它与 async/await 运行时有关，但我是 Rust 语言的新手，我在网上找到的关于这个问题的信息对我来说并不清楚。

如果有人可以帮助解决这些问题，我将不胜感激！

提前致谢！

丹尼·P。

是的你可以！

Rust Playground 提供 reqwest crate并允许绑定端口，因此您至少可以建立本地网络连接。只需带上您自己的 HTTP 服务器！

如果你想玩 reqwest，这可能就是你所需要的（在发布模式下运行它，因为连接更有可能在调试模式下获得）： https ://play.rust-lang.org/?version=stable&mode =release&edition=2021&gist=57b32e98df970013ffb8f83361a0b9c6

use std::io::Read;
use std::{thread};

use std::io::prelude::*;
use std::net::TcpListener;

const PORT: u16 = 18030;

fn main() {
    
    thread::spawn(|| {
        let listener = TcpListener::bind(format!("127.0.0.1:{}", PORT)).unwrap();
    
        for stream in listener.incoming() {
            let mut stream = stream.unwrap();
            let response = "HTTP/1.1 200 OK\r\n\r\nHello World";
            stream.write(response.as_bytes()).unwrap();
            stream.flush().unwrap();
            break;
        }
    });
    
    let mut res = reqwest::blocking::get(format!("http://127.0.0.1:{}", PORT)).expect("Connect");
    let mut body = String::new();
    res.read_to_string(&mut body).expect("Body");

    println!("Status: {}", res.status());
    println!("Body:\n{}", body);
}

这是reqwest版本的问题。将您的原始版本替换为

reqwest = { version = "0.11" }

在您的 Cargo.toml 中应该在您的本地机器上修复它。
