这是我的 asgi.py 文件：

import os
import django
from channels.routing import get_default_application
from channels.layers import get_channel_layer

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'ProfilesApp.settings.development')
django.setup()
application = get_default_application()
channel_layer = get_channel_layer()

设置.py

ASGI_APPLICATION = "ProfilesApp.routing.application"
WSGI_APPLICATION = 'ProfilesApp.wsgi.application'
CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "channels_redis.core.RedisChannelLayer",
        "CONFIG": {
            "hosts": [os.environ.get('REDIS_URL', 'redis://localhost:6379')],
        },
    },
}

请让我知道如何解决这个问题，在此先感谢

解决方案

您使用了错误的 asgi 配置，该配置适用于通道 1.x

作为文档状态应该看起来像

"""
ASGI entrypoint. Configures Django and then runs the application
defined in the ASGI_APPLICATION setting.
"""

import os
import django
from channels.routing import get_default_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproject.settings")
django.setup()
application = get_default_application()
