I am currently using Django channels for websocket communication. I read
this
<https://django-websocket-redis.readthedocs.io/en/latest/running.html#django-with-websockets-for-redis-behind-nginx-using-uwsgi>
article
and it states that I should split the project into two uwsgi instances. It
states that
"The web server undertakes the task of dispatching normal requests to one
> uWSGI instance and WebSocket requests to another one"
Now I have two uwsgi instances running. This is how I am running both.
This uwsgi handles the normal django site requests
uwsgi --virtualenv /home/ec2-user/MyProjVenv --socket /home/ec2-user/
MyProjVenv/MyProjWeb/site1.socket --chmod-socket=777 --buffer-size=32768 --
workers=5 --master --module main.wsgi
This uwsgi handles the websocket requests
uwsgi --virtualenv /home/ec2-user/MyProjVenv --http-socket /home/ec2-user/
MyProjVenv/MyProjWeb/web.socket --gevent 1000 --http-websockets --workers=2
--master --chmod-socket=777 --module main.wsgi_websocket
Now the websocket uwsgi launches main.wsgi_websocket
The code for main.wsgi_websocket one is this
import os
import gevent.socket
import redis.connection
redis.connection.socket = gevent.socket
os.environ.update(DJANGO_SETTINGS_MODULE='main.settings')
from ws4redis.uwsgi_runserver import uWSGIWebsocketServer
application = uWSGIWebsocketServer()
Now after spinning up the two uwsgi instances I am able to access the
website.The websocket uwsgi instance is also receiving data however I am
not sure if its passing that data to the website uwsgi instance. I am using
Django Channels here and this is the configuration I have specified in my
settings for Django Channels
CHANNEL_LAYERS = {
"default": {
"BACKEND": "asgi_redis.RedisChannelLayer",
"CONFIG": {
"hosts": [(redis_host, 6379)],
},
"ROUTING": "main.routing.channel_routing",
},
}
The channel routing is this
channel_routing = [
include("chat.routing.websocket_routing", path=r"^/chat/stream"),
include("chat.routing.custom_routing"),
]
and this is the websocket_routing which i have mentioned above
websocket_routing = [
route("websocket.connect", ws_connect),
# Called when WebSockets get sent a data frame
route("websocket.receive", ws_receive),
# Called when WebSockets disconnect
route("websocket.disconnect", ws_disconnect),
]
Now the problem is that my ws_receive is never called. If I test on my
local dev machine using "*ipaddress:8000/chat/stream*" this works
perfectly fine however I have no clue why my receive is not being called
when I use *ipadress:80/ws/ *. I am certain that my other uwsgi instance is
getting that data but I dont know how to find out if its passing it to the
other uwsgi instance of the djnago side and if it is then why is my receive
not being called ?. Any suggestions on this would definitely help
