Django Rest API POST问题

Question

I'm trying to build a very simple REST API in Django 1.8 with Django REST Framework in Visual Studio, in which I want to have a single service method to process a JSON, but I can't seem to make a POST:

I'm trying to send this simple JSON through Postman, just as a test:

{
   "foo":"bar"
}

with the header:

Content-Type: application/json

Here's my method:

@csrf_exempt
@api_view(['POST'])
def test(request):
    data = request.data
    return HttpResponse(status=200)

But my problem is that request.data is empty. And if instead I try to access request.body, I get

You cannot access body after reading from request's data stream.

Any ideas what could be the issue here?

Answer 1

Figured this out somewhat, it seems to be an issue with Visual Studio while in debug mode. If I try to access the request while debugging before calling any Python function on it (such as a simple print, or passing in to a function to parse it), it shows up as an empty QueryDict, otherwise it shows up fine.

Answer 2

Just a guess: maybe the issue is in Postman?

Try to send POST-request without headers, but with raw JSON (not form-data):

Answer 3

This may help Where's my JSON data in my incoming Django request?

Outside of this, make sure the content-type and accept-type are set properly. What is the raw response in Postman? Is the security setup properly?

Answer 4

I have the same problem when using POSTMAN.
