I'm newbie to django. I'm creating a simple app that posts user data to Django server. But I'm facing a problem regarding queryDict. It's empty. The code is:

@csrf_exempt

def create_user(request):

    

    This function creates users

    :param request: post request from front-end

    :return: success/failure

    

    if request.method == 'POST':

        #x = json.loads(request.POST)

        print(request.POST)

        return JSONResponse(request.POST)

The POST request is :

function post(){

    xmlhttp = new XMLHttpRequest();

    var url = http://127.0.0.1:8000/create_user/;

    xmlhttp.open(POST, url, true);

    //xmlhttp.setRequestHeader(Content-type, application/json);

    xmlhttp.onreadystatechange = function () { //Call a function when the state changes.

    if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {

        alert(xmlhttp.responseText);

        }

    }

    var parameters = {

        username: myname,

        password: mypass

    };

    xmlhttp.send(JSON.stringify(parameters));

}
