Simple example of websocket proxy / tunnel / redirection in Python

websocket_tunnel.py

uri = "wss://some_address:3214"
s = 'greetings'
import asyncio
import websockets

async def hello(websocket, path):
    async with websockets.connect(uri) as client:
        await client.send(s) #optional init on connection start
        while True:
            data = await client.recv()
            await websocket.send(data)

start_server = websockets.serve(hello, "localhost", 1234)

asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()
