这确实令人沮丧，我确实按照文档进行了所有设置，但是当我尝试独立运行daphne时，它总是抛出错误，当我使用python manage.py run server时，它可以正常工作。这非常令人沮丧，我似乎在其他任何地方都找不到类似的错误

这是我的asgi.py

import os

from django.core.asgi import get_asgi_application

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

application = get_asgi_application()

我的routing.py：

from django.urls import re_path
from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter,URLRouter
from channels.security.websocket import AllowedHostsoriginValidator,OriginValidator
import judge.routing

application = ProtocolTypeRouter({
    # (http->django views is added by default)
    'websocket': AllowedHostsoriginValidator(
        AuthMiddlewareStack(
            URLRouter(
                judge.routing.websocket_urlpatterns
            )
        )
    ),})

并在我的settings.py中：

INSTALLED_APPS = [
    ...
    'channels',]
...
WSGI_APPLICATION = 'tabulator.wsgi.application'
ASGI_APPLICATION = "tabulator.routing.application"
...
CHANNEL_LAYERS = {
    "default": {
        'BACKEND': 'channels_redis.core.RedisChannelLayer','CONFIG': {
            "hosts": [('127.0.0.1',6379)],},}
