I am using Django with django channels I am going off of Andrew Godwins django channels examples the "MultiChat" example I am using Webfaction and Putty to try and get it going here is the code I got:
settings.py
redis_host = os.environ.get('REDIS_HOST', 'localhost')
CHANNEL_LAYERS = {
"default": {
# This example app uses the Redis channel layer implementation asgi_redis
"BACKEND": "asgi_redis.RedisChannelLayer",
"CONFIG": {
"hosts": [(redis_host, 27411)],
},
"ROUTING": "myproject.routing.channel_routing",
},
}
我确实在这里有一个问题我会改变它是否将localhost改为我的网站的IP地址，还是在使用redis时将其保留为localhost？
至于我的index.html我有这个不确定这个代码是否需要调整或更新任何帮助表示赞赏谢谢。

如果您的redis与wepapp位于同一位置，则可以将localhost设置为redis IP地址。
settings相同的端口？
