Question

我正在按照https://realpython.com/getting-started-with-django-channels/的教程使用Django频道。

它正在使用django==1.10.5 channels==1.0.2 asgi_redis==1.0.0。

零件很少

main_app / routing.py：

from channels.routing import route
from example.consumers import ws_connect, ws_disconnect


channel_routing = [
    route('websocket.connect', ws_connect),
    route('websocket.disconnect', ws_disconnect),
]

example / views.py：

def user_list(request):
    return render(request, 'example/user_list.html')

example / consumers.py：

from channels import Group

def ws_connect(message):
    Group('users').add(message.reply_channel)

def ws_disconnect(message):
    Group('users').discard(message.reply_channel)

应用程序很小，但是当我尝试运行服务器时，出现以下错误：

当我访问主页localhost：8000时，它说“连接被拒绝”。如何删除此错误并使应用运行？
