Using django CSRF middleware with views returning JsonResponse

Question

I want to use CSRF middleware with API Views in Django. Here is a demo view I want to use CSRF with, I am confused how to integrate CSRF here.

def login(request):
    try:
        if len(DemoTable.objects.filter(phone=int(request.POST['user'])).filter(password=sha1Engine(request.POST['password'])))==1:
            print(DemoTable.objects.filter(phone=int(request.POST['user'])).filter(password=sha1Engine(request.POST['password'])))
            return JsonResponse({'exit':'0','msg':'Success'})
        return JsonResponse({'exit':'2','msg':'User Invalid'})
    except Exception as e:
        return JsonResponse({'exit':'10','msg':'Unknown Error Occured'})

Any help or suggestions will be appreciated. Thanks.

Answer 1

You can get the token with django.middleware.csrf.get_token(request)

And then set it in the header of the requests made client-side https://docs.djangoproject.com/en/2.0/ref/csrf/#setting-the-token-on-the-ajax-request

To set the cookie in the response, use the @ensure_csrf_cookie decorator:

from django.views.decorators.csrf import ensure_csrf_cookie

@require_http_methods(["GET"])
@ensure_csrf_cookie
def list_things(request):
    return JsonResponse({
        "things": ["foo", "bar"],
    })

$ curl -i http://localhost:8000/api/v1/things
HTTP/1.1 200 OK
Content-Type: application/json
Vary: Cookie
Set-Cookie:  csrftoken=nm4SdMB0pobkQ1ab7wZTFdwMlX8wr0vfT4iAg6Nqpcatl7ITRi9VOHrKf0Krbp2i; expires=Thu, 05 Mar 2020 15:25:53 GMT; Max-Age=31449600; Path=/; SameSite=Lax

{"things": ["foo", "bar"]}
