Webservice call using IXMLHttpRequest undesired response Text - c++

Question

Using IXMLHttpRequest to fetch the data from the webservice.(actually, java servlets file). Using below code to send request and get response from webservice
IXMLHTTPRequestPtr pIXMLHTTPRequest = NULL;
CoInitialize(nullptr);
String usBuffer;
CATTry
{
hr = pIXMLHTTPRequest.CreateInstance("Msxml2.XMLHTTP.6.0");
if (SUCCEEDED(hr) && (pIXMLHTTPRequest != NULL))
{
hr = pIXMLHTTPRequest->open("POST", "URL", false);
if (SUCCEEDED(hr))
{
String lsusHeaderName;
lsusHeaderName.Append("Content-Type: application/x-www-form-urlencoded");
lsusHeaderName.Append("Accept: */*");
lsusHeaderName.Append("ticket: " + "ticketvalue");
lsusHeaderName.Append("Context: " + "securityvalue");
for (int i = 1; i <= ilsusHeaderName.Size(); i++)
{
BSTR bstrHeaderName;
BSTR bstrHeaderValue;
ilsusHeaderName[i].ConvertToBSTR(&bstrHeaderName);
hr = pIXMLHTTPRequest->setRequestHeader(bstrHeaderName, bstrHeaderValue);
}
String iusRequestParam = "Type=xxxx&Name=xxxxytr&Revision=09";
if (iusRequestParam != "")
{
hr = pIXMLHTTPRequest->send(iusRequestParam.ConvertToChar());
}
else
{
hr = pIXMLHTTPRequest->send();
}
{
struct __timeb64 t_stime;
struct __timeb64 t_ctime;
long lProcTime = 0;
memset(&t_stime, 0, sizeof(struct __timeb64));
memset(&t_ctime, 0, sizeof(struct __timeb64));
long nRedyState = READYSTATE_UNINITIALIZED;
_ftime64(&t_stime);
while (nRedyState != READYSTATE_COMPLETE)
{
_ftime64(&t_ctime);
lProcTime = (long)(1000 * (t_ctime.time - t_stime.time) + (t_ctime.millitm - t_stime.millitm));
if (lProcTime > HTTP_TIMEOUT)
{
break;
}
nRedyState = pIXMLHTTPRequest->readyState;
}
}
std::cout << "Request status : " << pIXMLHTTPRequest->status << std::endl;
if ((pIXMLHTTPRequest->status == 200))
{
_bstr_t spbstrResponse = pIXMLHTTPRequest->responseText;
BSTR bstrString = NULL;
bstrString = spbstrResponse.GetBSTR();
usBuffer.BuildFromBSTR(bstrString);
usOutput = usBuffer;
std::cout << "Output : " << usBuffer << std::endl;
bstrString = NULL;
}
else
{
std::cout << "Failed to send GET/POST Method." << std::endl;
}
}
else
{
hr = E_FAIL;
}
}
}
}
CATCatch(CATError, pError)
{
std::cout << "Failed to query XMLHTTP 6.0. Perhaps MSXML 6.0 is not exists." << std::endl;
}
CATEndTry;
This webservice call returns 200 status code, but response text is not good.It returns some html,javascript code as response text.
Expected result is one of the attribute value of the passed object. Example output:
{
"logy": "646F916E00005E78609AC53D0000974F"
}
Couldn't locate the issue in this code, why it returns html,javascript code.As I am new to WINAPI concepts, your help is highly appreciated.
Edit:
Checked webservice via postman and it returns expected result.

Header should be passed in this way. This solved the issue.
CATListOfCATUnicodeString lsusHeaderName;
CATListOfCATUnicodeString lsusHeaderValue;
lsusHeaderName.Append("Content-Type");
lsusHeaderValue.Append("application/x-www-form-urlencoded");
lsusHeaderName.Append("Login-ticket");
lsusHeaderValue.Append(usLoginTicket);
lsusHeaderName.Append("SecurityContext");
lsusHeaderValue.Append(usSecurityContext);
