Different environment in wsgi request object - django

Question

After some hours of reading manuals and other helps, finally i got my nginx+uwsgi1.9+django1.6+python3.3 server.
But now I have problems (mb problem in my understanding something) - how to get POST data from request ? I mean how to get it correctly.
The code in django view:
def info(request):
print(request)
return HttpResponse(request)
request to server:
http://127.0.0.1:8000/info/
{
"test":"test"
}
and interesting part - output in uwsgi log (POST and GET dicts):
<WSGIRequest
path:/info/,
GET:<QueryDict: {}>,
POST:<QueryDict: {}>,
COOKIES:{},
META:{'CONTENT_LENGTH': '24',
'CONTENT_TYPE': 'application/json',
'CSRF_COOKIE': 'upJxA8TWO0nhKACr0dfU46Qyu0DzzUTR',
'DOCUMENT_ROOT': '/usr/share/nginx/html',
'HTTP_ACCEPT': '*/*',
'HTTP_ACCEPT_ENCODING': 'gzip,deflate,sdch',
'HTTP_ACCEPT_LANGUAGE': 'ru-RU,ru;q=0.8,en-US;q=0.6,en;q=0.4',
'HTTP_CONNECTION': 'keep-alive',
'HTTP_CONTENT_LENGTH': '24',
'HTTP_CONTENT_TYPE': 'application/json',
'HTTP_COOKIE': '',
'HTTP_HOST': '127.0.0.1:8000',
'HTTP_ORIGIN': 'chrome-extension://hgmloofddffdnphfgcellkdfbfbjeloo',
'HTTP_USER_AGENT': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.114 Safari/537.36',
'PATH_INFO': '/info/',
'QUERY_STRING': '',
'REMOTE_ADDR': '127.0.0.1',
'REMOTE_PORT': '53315',
'REQUEST_METHOD': 'POST',
'REQUEST_URI': '/info/',
'SCRIPT_NAME': '',
'SERVER_NAME': 'django',
'SERVER_PORT': '8000',
'SERVER_PROTOCOL': 'HTTP/1.1',
'uwsgi.node': b'',
'uwsgi.version': b'1.9.18.2',
'wsgi.errors': <_io.TextIOWrapper name=2 mode='w' encoding='UTF-8'>,
'wsgi.file_wrapper': <built-in function uwsgi_sendfile>,
'wsgi.input': <uwsgi._Input object at 0x7fa4ec6b8ee8>,
'wsgi.multiprocess': True,
'wsgi.multithread': False,
'wsgi.run_once': False,
'wsgi.url_scheme': 'http',
'wsgi.version': (1, 0)}>
and response in browser (same as request to server):
{
"test":"test"
}
What I'm doing wrong ?
request.POST
and
request.POSt.dict()
returns empty dicts.
So questions is how to get POST data in code and why it looks so different when I use environment ?
UPD:
return HttpResponse(str(request)) - returns WSGIRequest object instead of POST data to me. But still dont know how to get POST data in code.
UPD2:
uwsgi config:
[uwsgi]
module = mysite.wsgi
master = true
processes = 5
socket = :8001
daemonize = /var/log/uwsgi/mysite.log
touch-reload = /tmp/uwsgi-touch
post-buffering = 1
UPD3:
versions of software:
Python 3.3.2
Django 1.6.2
uWSGI 1.9.18.2
UPD4:
Final code:
if request.method == "POST":
if request.META["CONTENT_TYPE"] == "application/json":
result = json.loads(request.body.decode())
else: result = request.POST.dict()
return HttpResponse(json.dumps(result), content_type="application/json")
Thats what I exactly want.
When I send data to server with
POST
Content-Type: application/x-www-form-urlencoded
a=1
or:
POST
Content-Type: application/json
{"a":"1"}
I see same response (and in code variables):
Content-Type: application/json
{"a": "1"}

Looks like you a POSTing JSON data, not HTML form data.
In that case you are looking for the raw post data, which is accessed like this:
request.body
See HttpRequest.body in the documentation.
If you want to parse that JSON string, use this:
import json
data = json.loads(request.body)
The request.POST dictionary is only populated when the request contains form data. This is when the Content-Type header is application/x-www-form-urlencoded or multipart/form-data.
