问题描述
这真的很令人沮丧,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运行服务器时,它确实可以正常工作代码>.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
This is really frustrating, I did set everything up according to the documentation, but daphne keeps throwing an error when I try to run it independently, it does work correctly when I use python manage.py run server
. this is very frustrating and I can't seem to find similar error anywhere else

这是我的asgi.py
here is my 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:
my 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:
and in my settings.py:
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)],
},
},
}
推荐答案
将您的 asgi.py
更改为此:
import os
import django
from channels.routing import get_default_application
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'tabulator.settings')
django.setup()
application = get_default_application()
