I want to integrate Django Channels.I have installed all required dependencies,and while starting the app server starts listening on TCP address 127.0.0.1:8000. My routing is specified as follows:
websocket_urlpatterns = [
url(r'^ws/chat/(?P<room_name>[^/]+)/$', consumer.ChannelConsumer),
]
And the Consumer file:
from channels.generic.websocket import AsyncWebsocketConsumer
import json
class ChannelConsumer(AsyncWebsocketConsumer):
async def connect(self):
# self.room_name = self.scope['url_route']['kwargs']['room_name']
# self.room_group_name = 'chat_%s' % self.room_name
#
# # Join room group
# await self.channel_layer.group_add(
# self.room_group_name,
# self.channel_name
# )
await self.accept()
async def disconnect(self, close_code):
# Leave room group
await self.channel_layer.group_discard(
self.room_group_name,
self.channel_name
)
# Receive message from WebSocket
async def receive(self, text_data):
text_data_json = json.loads(text_data)
message = text_data_json['message']
# Send message to room group
await self.channel_layer.group_send(
self.room_group_name,
{
'type': 'chat_message',
'message': message
}
)
# Receive message from room group
async def chat_message(self, event):
message = event['message']
# Send message to WebSocket
await self.send(text_data=json.dumps({
'message': message
}))
However I cant open connection. Handshake fails
Delete ROUTING on CHANNEL_LAYERS settings
And change BACKEND to channels_redis.core.RedisChannelLayer
Example:
CHANNEL_LAYERS = {
"default": {
"CONFIG": {
"hosts": [('localhost','6379')],
},
"BACKEND": "channels_redis.core.RedisChannelLayer",
},
}
This happens just if you are upgrading channels 1.X to 2
