Question about accessing data from REST-ful resource using c++ and poco - c++

Question

I have succesfully retrieved the data using a java HttpURLConnection and setting request method as "GET". I would like to implement this in c++ as well (I'm using poco). The URL I am trying to access is "https://open.faceit.com/data/v4".
When I send the request I get a status code 400 (Bad Request) and the response message "400 The plain HTTP request was sent to HTTPS port". Why would using HTTP in java work, but using POCO in c++ I get this error? Should I be using HTTPSClientSession instead, and if so why was I able to use HTTP in java?
java code that gives return code 200
URL url = new URL(dataURL);
HttpURLConnection hc = (HttpURLConnection) url.openConnection();
hc.setRequestMethod("GET");
hc.setRequestProperty("Authorization", "Bearer " + code);
hc.setDoOutput(true);
int rCode = hc.getResponseCode();
c++ thats giving me return 400
Poco::URI uri("https://open.faceit.com/data/v4/players?nickname=FadesfasT&game=CSGO");
std::string path(uri.getPathAndQuery());
HTTPClientSession session(uri.getHost(), uri.getPort());
HTTPRequest request(HTTPRequest::HTTP_GET, path, HTTPMessage::HTTP_1_1);
request.add("Authorization", "Bearer" + token);
request.setContentType("application/json");
session.sendRequest(request);
HTTPResponse response;
std::istream& in_stream = session.receiveResponse(response);
std::ostringstream out_stream;
Poco::StreamCopier::copyStream(in_stream, out_stream);
std::cout << out_stream.str() << std::endl;

Answer 1

The problem with your C++ snippet is that you are mixing an URL containing a HTTPS address with a request targeting HTTP.
My uneducated guess about why the issue does not appear in Java is that it recognizes the 'https' in the address and automatically uses an appropriate handler for that. Fact is, in C++ or at least in POCO you have to pick the appropriate request yourself.
Basically you have 3 options:
Use a HTTP URL with the HTTP request that you have already written.This does not really seem to be an option, because your URL redirects HTTP to HTTPS so this would not work.
Use a HTTPS URL and change your request to HTTPS. It might be more difficult than option 1, but not that hard and there exists a SO question discussing this. To summarize:
Should I be using HTTPSClientSession instead [...] ?
Yes, if you decide to go with this option
Use a library other than POCO, which seems to be the solution in your case as mentioned in the comments. I for example know of CURL and libhttp, which imo are at least as easy to use as POCO, if not easier. The links lead to pages containing examples on how to execute HTTPS requests.
