1. Create an example view with Django 2.1.4 that does not consume the
request's body:
{{{
@csrf_exempt
def myview(request):
#print(request.body.decode("utf8"))
return HttpResponse()
}}}
2. Now send a a first POST with **application/json** content type, e.g.
with axios:
{{{
axios.post("/myview", {"some": "data"})
}}}
3. Send new identical POST requests, and observe that they cause HTTP 400
errors:
{{{
[17/Jan/2019 22:27:47] "POST /myview HTTP/1.1" 200 0
[17/Jan/2019 22:27:48] "{"some":"data"}POST /myview HTTP/1.1" 200 0
[17/Jan/2019 22:29:44] code 400, message Bad request syntax
('{"some":"data"}')
[17/Jan/2019 22:29:44] "{"some":"data"}" 400 -
}}}
The JSON payload of the first request is still buffered somewhere and mess
up later requests.
4. Now comment out the print function is the view, and see that consuming
the payload has fixed the issue
