Hi,
I am testing to receive underlying options from a chain using the WebSocketAPI with Python in Windows.
Error message:
"Future exception was never retrieved
future: <Future finished exception=ConnectionClosedOK(Close(code=1001, reason='Going Away'), Close(code=1000, reason=''), False)>
websockets.exceptions.ConnectionClosedOK: sent 1000 (OK); then received 1001 (going away) Going Away"
It fails each time on loop 977.
Any advise on the meaning of this error and a possible resolution is appreciated. Simple code enclosed below (removed connection details):
import asyncio import json import socket import websockets hostname = '' port = '' ws_address = "ws://{}:{}/WebSocket".format(hostname, port) user = '' app_id = '' position = socket.gethostbyname(socket.gethostname()) login_json = { 'ID': 1, 'Domain': 'Login', 'Key': { 'Name': '', 'Elements': { 'ApplicationId': '', 'Position': '' } } } login_json['Key']['Name'] = user login_json['Key']['Elements']['ApplicationId'] = app_id login_json['Key']['Elements']['Position'] = position async def hello(initial_name): store = [] #websocket vs websockets async with websocket.connect(ws_address, extra_headers={'User-Agent': 'Python'}, subprotocols=['tr_json2'], ping_timeout=None, ping_interval=5) as websocket: await websocket.send(json.dumps(login_json)) await websocket.recv() async def get_data_for_name(message): await websocket.send(json.dumps({ 'ID': 2, 'Key': { 'Name': message, 'Service': '$svc', }, "Streaming": False })) res = await websocket.recv() json_res = json.loads(res[1:-1]) store.append(json_res) print(json_res) if len(json_res['Fields']['BR_NEXTLR']) > 0: await get_data_for_name(json_res['Fields']['BR_NEXTLR']) await get_data_for_name(initial_name) asyncio.run(hello('0#$chain'))
Kind regards,
Johan
