not receiving proper WebSocket data

pavank

I’m trying to access data from web socket using smartapi-python, but I’m only receiving heartbeat data and some other data. Please do needful.

Request:
client_code="********" #client code is set in actual script
task="mw"
token="nsc_cm|15083"
ss = WebSocket(feed_token , client_code)
def on_tick(ws, tick):
for feed_data in tick:
print(feed_data)
def on_connect(ws, response):
print("connecting websocket")
print(task)
ws.send_request(token,task)

def on_close(ws, code, reason):
print("closing websocket")
ws.stop()

ss.on_ticks = on_tick
ss.on_connect = on_connect
ss.on_close = on_close
ss.connect( )

Note: login successful and feed token set

Response:
{'ak': 'ok', 'msg': 'connected', 'task': 'cn'}
{'ak': 'ok', 'msg': 'mw', 'task': 'mw'}
{'ak': 'ok', 'msg': 'heartbeat', 'task': 'hb'}
{'name': 'tm', 'tvalue': '12/03/2021 10:13:05'}

@nirav

can you please share the code and your sdk version ( if you are using python )

admin

@rajanprabu @ nirav
kindly generate feed token and use below code.

ss = WebSocket(FEED_TOKEN, CLIENT_CODE)

def on_tick(ws, tick):
print("Ticks: {}".format(tick))

def on_connect(ws, response):
ws.send_request(token)

def on_close(ws, code, reason):
ws.stop()

Assign the callbacks.

ss.on_ticks = on_tick
ss.on_connect = on_connect
ss.on_close = on_close

ss.connect( )`

@admin said in not receiving proper WebSocket data:

ws.send_request(token)

for SDK version 1.2.2 onwards this needs to be

ws.send_request(token,task)

where task is task="mw", #'mw'|'sfi'|'dp'

@nirav

No, OI is not streamed via WebSocket. It's yet to be added in WebSocket response.

James Bond

@admin
Can you give any rough estimate when will you start streaming OI ?

nirav

@admin

tnx

admin

HI @nirav we have noticed your query we will update you on this.

@nirav

This normally happens with network drop. If you are using new python SDK, you may potentially overcome this.

nirav

@rajanprabu
sir i have install python sdk just tomorrow, so its a latest. till i getting heart beat. any solution for this by api team or not. my deadline is very close. suggest me asap

tnx

@nirav

Its hard to suggest with fewer details available. Are you running it on the cloud or at home with Wifi ? WiFi drop can also cause this.
