How to send message...

[Arti3DPlayer]

I have event:

@on_message
def message(request, socket, context, message):
    print message

When i try to connect and send message:

from websocket import create_connection
ws = create_connection("ws://127.0.0.1:9000/")
ws.send("Hello, World")

I receive error:

websocket._exceptions.WebSocketException: Handshake status 200

In another try i create view - send message to url and the same result...
