在Rust中使用websocket时，有没有办法通过代理进行连接？

使用reqwest，您可以使用如下代理服务器：

let client = reqwest::Client::builder()?
    .proxy(reqwest::Proxy::http("https://my.proxy.local:1080")?)
    .build()?;

extern crate futures;
extern crate tokio;
extern crate websocket;

use websocket::Message;
use websocket::result::WebSocketError;
use websocket::{ClientBuilder, OwnedMessage};
use websocket::header::{Headers, Authorization, Basic};
use websocket::futures::{Future, Stream, Sink};
use tokio_core::reactor::Core;

const CONNECTION: &'static str = "wss://some.remote.host.example.org:443/";

let mut core = Core::new()?;
let client = ClientBuilder::new(CONNECTION)?
   .async_connect_secure(None)  
   .and_then(|(msg, _)| match msg {
       Some(OwnedMessage::Text(response_txt)) => Ok(response_txt),
       _ => Err(WebSocketError::ProtocolError(UNSUPPORTED_MSG_ERR)),
   });

let response_message = core.run(client)?;

我使用的websocket如下所示：

let client = reqwest::Client::builder()?
    .proxy(reqwest::Proxy::http("https://my.proxy.local:1080")?)
    .build()?;

extern crate futures;
extern crate tokio;
extern crate websocket;

use websocket::Message;
use websocket::result::WebSocketError;
use websocket::{ClientBuilder, OwnedMessage};
use websocket::header::{Headers, Authorization, Basic};
use websocket::futures::{Future, Stream, Sink};
use tokio_core::reactor::Core;

const CONNECTION: &'static str = "wss://some.remote.host.example.org:443/";

let mut core = Core::new()?;
let client = ClientBuilder::new(CONNECTION)?
   .async_connect_secure(None)  
   .and_then(|(msg, _)| match msg {
       Some(OwnedMessage::Text(response_txt)) => Ok(response_txt),
       _ => Err(WebSocketError::ProtocolError(UNSUPPORTED_MSG_ERR)),
   });

let response_message = core.run(client)?;

有没有一种方法可以将https或socks代理与websocket一起使用？

设置env变量代理时会发生什么？哪一种？但是，是的，我设置了它们，因为我在代理后面使用了curl、wget、git、node、composer等。实际上，rust reqwest以某种方式使用了系统代理，我必须调用.no_proxy（），以防止在连接到本地资源时通过代理，但websocket不会。如果设置了系统代理而websocket未通过，则可能是您的代理未配置为允许websocket通过
