How to get current user from Django network packet package?

Question

I followed this tutorial: Finally, Django in real time is here: start with Django channels .

I wanted to extend the application using Django user objects instead of a variable handle. But how can I get the current user from the received WebSocket package in my function ws_recieve(message)?

I noticed that both csrftoken, and the first ten digits sessionidfrom the web socket package correspond to normal HTTP requests. Can I get the current user with this information?

For reference, the resulting package is as follows:

{'channel': <channels.channel.Channel object at 0x110ea3a20>,
 'channel_layer': <channels.asgi.ChannelLayerWrapper object at 0x110c399e8>,

                          b'zckszpuqphn0egqh22wqaj'],
                         [b'cache-control', b'no-cache'],
                         [b'sec-websocket-version', b'13'],
                         [b'sec-websocket-extensions',
                          b'x-webkit-deflate-frame'],
                         [b'host', b'0.0.0.0:8000'],
                         [b'upgrade', b'websocket'],
                         [b'sec-websocket-key', b'y2Lmb+Ej+lMYN+BVrSXpXQ=='],
                         [b'user-agent',

                         [b'pragma', b'no-cache']],
             'order': 0,
             'path': '/chat-message/',
             'query_string': '',
             'reply_channel': 'websocket.send!UZaOWhupBefN',

2018 :

, self.scope [ "user" ] :

class ChatConsumer(WebsocketConsumer):

    def connect(self, event):
        self.user = self.scope["user"]

    def receive(self, event):
        username_str = None
        username = self.scope["user"]
        if(username.is_authenticated()):
            username_str = username.username
            print(type(username_str))
            #pdb.set_trace() # optional debugging
