Open an App by connecting to Qlik Sense Engine API using python

Hi All,

I am able to connect to Qlik Sense Desktop Engine API using this below python script :

from websocket import create_connection

import json

ws = create_connection("ws://localhost:4848/app/")

data=json.dumps({

'jsonrpc': '2.0',

'id': 2,

'method': 'DoReload',

'handle': 1,

'params': ['C:\\Users\\sbhowmik\\Documents\\Qlik\\Sense\\Apps\\Test.qvf']

}

# sort_keys=True,

#indent=4,

#separators=(',', ': ')
)

print("Sending req...")

ws.send(data)

print("Sent")

print("Receiving...")

result = ws.recv()

print("Received '%s'" % result)

qclosed = ws.close()
print("Closed '%s'" % qclosed)

The message I get in return from engine is as below :

{"jsonrpc":"2.0","method":"OnConnected","params":{"qSessionState":"SESSION_CREATED"}}

>> Problem Statement : But, the app Test.qvf does not open up AND also, I do not get any QReturn message from the Engine API . I maybe doing something wrong here. Please help.

Hi,

Continuously receiving this Invalid Params message when connecting with Desktop engine API, even though after successful connection with API. Please look innto this :

'{"jsonrpc":"2.0","method":"OnConnected","params":{"qSessionState":"SESSION_CREATED"}}'

'{"jsonrpc":"2.0","id":5,"error":{"code":-32602,"parameter":"Invalid handle","message":"Invalid Params"}}'
