How to receive json data using HTTP POST request in Django 1.6?
You're confusing form-encoded and JSON data here. request.POST['foo'] is for form-encoded data. You are posting raw JSON, so you should use request.body.
received_json_data=json.loads(request.body)
For python3 you have to decode body first:
received_json_data = json.loads(request.body.decode("utf-8"))
Create a form with data as field of type CharField or TextField and validate the passed data. Similar SO Question
