Panic on request challenge

[PaulDotSH]

When the code gets to

let url = resp.url().as_str().to_owned();

The thread panics, saying

'no entry found for key "set-cookie"'

It's due to this line:

let cookie = resp.headers()[SET_COOKIE].to_owned();

[winrid]

An easy fix is:

            match self.client.get(url).header(USER_AGENT, self.user_agent.as_str()).send() {
                Ok(resp) => {
                    let headers = resp.headers();
                    match headers.contains_key(SET_COOKIE) {
                        true => {
                            let url = resp.url().as_str().to_owned();
                            let cookie = resp.headers()[SET_COOKIE].to_owned();
                            match resp.text() {
                                Ok(text) => {
                                    let path = regex::Regex::new(r#"id="challenge-form" action="([^"]*)""#)
                                        .unwrap()
                                        .captures(&text)
                                        .unwrap()[1]
                                        .into();
                                    return (text, url, cookie, path);
                                }
                                Err(e) => eprintln!("At request_challenge() text(), {:?}", e),
                            }
                        }
                        false => {
                            eprintln!("Did not get SET_COOKIE header, trying again. {}", url);
                            sleep(Duration::from_secs(3));
                            // continue
                        }
                    }
                }
                Err(e) => eprintln!("At, request_challenge() send(), {:?}", e),
            }

but not sure this is a solution, not sure why not getting SET_COOKIE in response.
