Question

我正在关注本教程：https://gearheart.io/blog/creating-a-chat-with-django-channels/

运行manage.py runserver

时出现以下代码时出现此错误

#settings.py

redis_host = os.environ.get('REDIS_HOST', 'localhost')

# Channel layer definitions
# http://channels.readthedocs.org/en/latest/deploying.html#setting-up-a-channel-backend
CHANNEL_LAYERS = {
    "default": {
        # This example app uses the Redis channel layer implementation asgi_redis
        "BACKEND": "asgi_redis.RedisChannelLayer",
        "CONFIG": {
            "hosts": [(redis_host, 6379)],
        },
       "ROUTING": "gameapollius.routing.channel_routing", # We will create it in a moment
    },
}

#routing.py

from channels import route,include

def message_handler(message):
    print(message['text'])

channel_routing = [
    route('websocket.receive', message_handler)
]

WebSocketBadStatusException: Handshake status 200

我做错了什么？我已经按照教程到T直到“ws.connect（”ws：// localhost：8000“）”行。这是我被困的地方。任何帮助将不胜感激，提前谢谢。
