Hi

Can I use WebSocket on Oracle Cloud Free Tier?

from websocket_server import WebsocketServer

# Called for every client connecting (after handshake)

def new_client(client, server):

  print("New client connected and was given id %d" % client['id'])

  server.send_message_to_all("Hey all, a new client has joined us")

# Called when a client sends a message

def message_received(client, server, message):

  print("Client(%d) said: %s" % (client['id'], message[:50]))

  server.send_message_to_all(message)

PORT = 9001

server = WebsocketServer(port = PORT)

server.set_fn_new_client(new_client)

server.set_fn_message_received(message_received)

server.run_forever()

• Up code is not connected from outside.

Use (websockets) down code instead of (websocket) up code

----------------------------------------------------------------------------------------

import asyncio

import websockets

CONNECTED = []

async def handler(websocket):

CONNECTED.append(websocket)

  async for message in websocket:

print(message[:20])

websockets.broadcast(CONNECTED, message)

    

async def main():

  async with websockets.serve(handler, "", 9001):

    await asyncio.Future() # run forever

if __name__ == "__main__":

  asyncio.run(main())
