我正在尝试在我正在编写的 Rust 程序中使用这个 Python 脚本的一部分（取自这里）。如何构造具有相同内容的 reqwest 请求？
def login(login_url, username, password=None, token=None):
"""Log in to Kattis.
At least one of password or token needs to be provided.
Returns a requests.Response with cookies needed to be able to submit
"""
login_args = {'user': username, 'script': 'true'}
if password:
login_args['password'] = password
if token:
login_args['token'] = token
response = requests.post(login_url, data=login_args, headers=_HEADERS)
return response
def submit(submit_url, cookies, problem, language, files, mainclass='', tag=''):
"""Make a submission.
The url_opener argument is an OpenerDirector object to use (as
returned by the login() function)
Returns the requests.Result from the submission
"""
data = {'submit': 'true',
'submit_ctr': 2,
'language': language,
'mainclass': mainclass,
'problem': problem,
'tag': tag,
'script': 'true'}
sub_files = []
for f in files:
with open(f) as sub_file:
sub_files.append(('sub_file[]',
(os.path.basename(f),
sub_file.read(),
'application/octet-stream')))
return requests.post(submit_url, data=data, files=sub_files, cookies=cookies, headers=_HEADERS)
（查看上面的链接以获取其余代码）
目前我有这个（我不确定是否处理了cookie）
let config = get_config().await?;
let mut default_headers = header::HeaderMap::new();
default_headers.insert(
header::USER_AGENT,
header::HeaderValue::from_static("kattis-cli-submit"),
);
let client = reqwest::ClientBuilder::new()
.default_headers(default_headers)
.cookie_store(true)
.build()?;
// Login
let login_map = serde_json::json!({
"user": config.username.as_str(),
"script": "true",
"token": config.token.as_str(),
});
let login_response = client
.post(&config.login_url)
.header("Content-Type", "application/x-www-form-urlencoded")
.json(&login_map)
.send()
.await?;
println!("{:?}", login_response);
// Make a submission
let submission_map = serde_json::json!({
"submit": "true",
"submit_ctr": "2",
"language": language,
"mainclass": problem,
"problem": problem,
"script": "true",
});
println!("{}", &submission_map);
let mut form = multipart::Form::new();
let mut sub_file = multipart::Part::text(submission).file_name(submission_filename);
sub_file = sub_file.mime_str("application/octet-stream").unwrap();
form = form.part("sub_file[]", sub_file);
let submission_response = client
.post(&config.submit_url)
.json(&submission_map)
.multipart(form)
// .build();
.send()
.await?
.text()
.await?;
let config = get_config().await?;
let mut default_headers = header::HeaderMap::new();

POST 请求中存在一些差异，但我无法弄清楚到底是什么。我也认为我可以使用第一个请求登录，但我不完全确定 cookie 会继续存在。有没有一种通用的方法来重写 Rust 中的 Python 请求 POST？具体来说，我认为我需要包含文件部分。
