  Steps to reproduce

step 1 . When data posted to apiview , pprint the POST querydict.

@api_view(['GET', 'POST'])
def snippet_list(request):
if request.method == 'POST':
from pprint import pprint as pp
pp(request.data)
pp(request.POST)
serializer = SnippetSerializer(data=request.data)
if serializer.is_valid():
serializer.save()
return Response(serializer.data, status=status.HTTP_201_CREATED)
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

step 2 . Post '{"code": "print 123"}' from browsable api to snippet_list apiview.

Expected behavior

result of both pprint : {u'code': u'print 12dgdf3'}
<QueryDict: {}>

Actual behavior

result of both pprint : {u'code': u'print 12dgdf3'}
{u'code': u'print 12dgdf3'}
