SteamWorks http request returning weird characters

I'm trying to get SteamWorks to read from json data using get requests, but it doesn't matter what URL I use to do it (and I've confirmed its valid json) it always returns weird characters.

PHP Code:


		
			
char response_body[4096];

public void SendRequest()
{
    char s_URL[] = "http://httpbin.org/get";
    char sParam[255] = "123";

    Handle handle = SteamWorks_CreateHTTPRequest(k_EHTTPMethodGET, s_URL);

    SteamWorks_SetHTTPRequestNetworkActivityTimeout(handle, 5);
    SteamWorks_SetHTTPRequestHeaderValue(handle, "Pragma", "no-cache");
    SteamWorks_SetHTTPRequestHeaderValue(handle, "Cache-Control", "no-cache");
    SteamWorks_SetHTTPRequestGetOrPostParameter(handle, "action", sParam);
    SteamWorks_SetHTTPRequestRawPostBody(handle, "application/json; charset=utf8;", sParam, sizeof(sParam));
    SteamWorks_SetHTTPCallbacks(handle, HTTP_RequestComplete);
    SteamWorks_SendHTTPRequest(handle);
}

public int HTTP_RequestComplete(Handle HTTPRequest, bool bFailure, bool bRequestSuccessful, EHTTPStatusCode eStatusCode)
{
    if(!bRequestSuccessful) {
        PrintToServer("Request failure");
    } else {
        SteamWorks_GetHTTPResponseBodyData(HTTPRequest, response_body, 4096);
        PrintToServer("response_body = %s", response_body);
        CloseHandle(HTTPRequest);
    }
}

And the server always prints this "response_body = UëÕh" which doesn't really make any sense to me.

Leading to this error:

Code:

L 07/25/2017 - 15:32:28: Info (map "ctf_2fort") (file "errors_20170725.log")

L 07/25/2017 - 15:32:28: [SMJSON] Error in line 1, col 1: unable to decode byte 0x89 near 'U'

L 07/25/2017 - 15:32:28: [SM] Exception reported: Invalid <JSON Object> handle 0 (error 4)

Any ideas?

Re: SteamWorks http request returning weird characters

The length parameter in SteamWorks_GetHTTPResponseBodyData(.., .., length); should be the actual length of response body received and not the max length of your buffer.

PHP Code:


		
			
int size;
SteamWorks_GetHTTPResponseBodySize(request, size);
SteamWorks_GetHTTPResponseBodyData(HTTPRequest, response_body, size);

In that case, I would recommend doing this as well:

PHP Code:


		
			
char[] response_body = new char[size];

You can also just use SteamWorks_GetHTTPResponseBodyCallback() and not worry about anything above.

Didn't realise that was a thing, thank you, solved it!
