I have multiple servers, each server is instance returning by asyncio.start_server. I need my web_server to works with websockets, to have possibility getting data using my javascript client. As I can see, asyncio do not provide websockets, only tcp sockets. Maybe I missed something ? I want to implement websocket server that I can using in asyncio.gather like below:
loop = asyncio.get_event_loop()
login_server = LoginServer.create()
world_server = WorldServer.create()
web_server = WebServer.create()
loop.run_until_complete(
asyncio.gather(
login_server.get_instance(),
world_server.get_instance(),
web_server.get_instance()
)
)
try:
loop.run_forever()
except KeyboardInterrupt:
pass
loop.close()
I do not want to use aiohttp cause if using like in code above aiohttp just blocks another tasks. I need something that will be non-blocking and that will have access to data of another servers (login and world). Does it possible with asyncio ? Does asyncio provide something like websockets ? How to implement websocket server for using in asyncio.gather ?
Well, finally I've implemented WebServer for using in another thread with asyncio. The code (WebServer code):
from aiohttp import web
class WebServer(BaseServer):
def __init__(self, host, port):
super().__init__(host, port)
@staticmethod
async def handle_connection(self, request: web.web_request):
ws = web.WebSocketResponse()
await ws.prepare(request)
async for msg in ws:
Logger.debug('[Web Server]: {}'.format(msg))
return ws
@staticmethod
def run():
app = web.Application()
web.run_app(app, host=Connection.WEB_SERVER_HOST.value, port=Connection.WEB_SERVER_PORT.value)
And how to run:
executor = ProcessPoolExecutor()
loop.run_until_complete(
asyncio.gather(
login_server.get_instance(),
world_server.get_instance(),
loop.run_in_executor(executor, WebServer.run)
)
)
