问题描述
我正在尝试在正在编写的Rust程序中使用this Python script（取自here）的一部分。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)
（请查看上面的链接以获取其余代码）
目前，我已经知道了（不确定cookie是否得到处理）
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,});
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();
default_headers.insert(
header::USER_AGENT,login_response);
// Make a submission
let submission_map = serde_json::json!({
"submit": "true",&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?;
println!("Submission response:\n{:?}",submission_response);

POST请求中存在一些差异，但是我无法确切知道是什么。我还认为我可以通过第一个请求登录，但是我不确定完全保留cookie。有没有一种通用的方法可以在Rust中重写Python请求POST？具体来说，我认为我需要包含文件部分。
