我在YouTube上观看了Dennis Ivy的教程：Django通道和WebSockets过于简化
我想在Django中使用websockets创建一个简单的网站。我使用Python 3.7.0
当我使用python manage.py runserver时，它输出以下Starting development server at http://127.0.0.1:8000/，但是，它应该输出以下Starting ASGI/Channels version 3.0.0 development server at http://127.0.0.1:8000/
这是我的settings.py文件

INSTALLED_APPS = [
    'channels',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'chat',
]

ASGI_APPLICATION = 'myWebsite.asgi.application'

asgi.py

import os

from django.core.asgi import get_asgi_application
from channels.routing import ProtocolTypeRouter 

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myWebsite.settings')

application = ProtocolTypeRouter({
    'http':get_asgi_application()
})
