如何将AJAX JSON发布请求从Jquery转换为Python / Django字典

Question

I am trying to convert an AJAX request retrieving JSON from JS to Python's dictionary in Django, but unsuccessfully. Please help.

This is the original JS code:

myJSON = JSON.stringify(myJsObject);

// POST - send JSON data to Python/Django server
$.ajax({
  url: "/savemyexposuresituation",
  type: "POST",
  datatype: 'json',
  data: myJSON,
  async: false,
  success: function() {
    alert('Your data is saved :)');
  },
  error: function() {
    alert('Error occured :(');
  }
});
}

This is the Django side:

def saveExposureSituation(request):

#get es data - JSON file
fromJs = request.POST

fromJs = json.loads(fromJs)

All I get is JSON object must be string, not QueryDict . I tried to convert this QueryDict to something else unsuccessfully.

Answer 1

request.POST is for form-encoded data. You should be using request.body .

Answer 2

In python 3 to convert byte to strings you need to use decode("utf-8") . So may be to something like this request.POST.decode("utf-8")

Answer 3

Thanks to responses, the complete answer would be:

def saveExposureSituation(request):

    fromJs = request.body
    fromJs = fromJs.encode('utf-8')

    #now we can load our JSON from JS
    fromJs = json.loads(fromJs)
