Django Channel Error

[Maitreya Verma]

I am following this tutorial to learn django channels. 

The following procedure was used :

• Add the following code in settings.py
  redis_host=os.environ.get('REDIS_HOST','localhost')

  
  

  CHANNEL_LAYERS={

      "default":{

          "BACKEND":"asgi_redis.RedisChannelLayer",

          "CONFIG":{

              "hosts":[(redis_host),6379],

          },

          "ROUTING":'channelproj.routing.channel_routing',

      },

  }
  
  
• Create a file routing.py and add the following code
  from channels import route

  # This function will display all messages received in the console

  def message_handler(message):

      print(message['text'])

  
  

  channel_routing = [

      route("websocket.receive", message_handler),

  ]
  
  
• run server using python manage.py runserver and then try to connect to server using  ws.connect("ws://localhost:8000/")

I am getting the following error

websocket._exceptions.WebSocketBadStatusException: Handshake status 200

What can be the reason for this error and how can it be rectified?

I am using Django 2.0, django-channels 0.7.0, asgi-redis 1.4.3

That error means you are not actually running a websocket-capable server. Did you add "channels" to INSTALLED_APPS?

Yes it worked. I had not installed channels and not added it to INSTALLED_CHANNELS as well. Thanks Andrew!
