I'm Using Rest framework to get JSON data and parse them. now I don't know how to access the second argument of json data, for parse the json I've seen this link.
code in views:
@api_view(['POST'])
@parser_classes((JSONParser,))
def product_list(request):
    """
    List all products which name of them is in the json data
    """
    if request.method == 'POST':
        print(request.data)
        MarketProduct=[]
        for item in request.data:
            print(item)
            try:
                product=Market.objects.get(name=item)
                MarketProduct.append(product)
            except Market.DoesNotExist:
                return Response(status=status.HTTP_404_NOT_FOUND)
        serializer = MarketSerializer(MarketProduct, many=True)
        return Response(serializer.data)
code in urls:
urlpatterns = [
    url(r'^listproducts/$', views.product_list),
]
here in this line: 
 for item in request.data:
the item only has the first argument of each json. 
the json which I've sent is :
{'hello': '1', 'bye': '2'}
in printing items , only "hello" and "bye" prints.but i want to access "1" and "2" too.
It's important for me to use Django framework. 
and I can't get the appropriate way to use json.load(raw) in this situation
