How to connect to the qlik engine api with python through a proxy (with windows authentication) ?

[sama007]

Hello,

I'm trying to connect to the qlik engine api with python but I can't. I read a post: https://community.qlik.com/t5/Official-Support-Articles/Qlik-Sense-call-Qlik-Sense-Engine-API-with-P...
which looks very useful but unfortunately it doesn't work for me.
In my case I have to connect to a corporate proxy which complicates my task even more.

I tried to pass a proxy to my connection using websocket but it doesn't work (WebSocketProxyException(
websocket._exceptions.WebSocketProxyException: failed CONNECT via proxy status: 307).
https://websocket-client.readthedocs.io/en/latest/examples.html#connecting-through-a-proxy

I have no idea if I'm going in the right direction, do you have any resources to help me?

Hello,

Could you post an example of your Code? Thank you very much.

This part of the WebSocet Documentation is very interesting.

import websocket

import ssl

import json

proxy_host = "XXX.XX.XXX.XX" #proxy server IP

proxy_port = XXXX            #proxy server port

my_session = 'XXXX-XXX-XXX-XXX-XXXX'

host = 'XXXXX'

websocket_key = 'XXXXXXXXX'

usr = 'XXXXX'

pswd = 'XXXXXXXXXXX'

header = {

    'Accept-Encoding': 'gzip, deflate, br',

    'Accept-Language': 'fr-FR,fr;q=0.9,en-US;q=0.8,en;q=0.7',

    'Cache-Control': 'no-cache',

    'Connection': 'Upgrade',

    'Cookie': 'X-Qlik-Session={my_session}',

    'Host': host,

    'Origin': f'https://{host}',

    'Pragma': 'no-cache',

    'Sec-WebSocket-Extensions': 'permessage-deflate; client_max_window_bits',

    'Sec-WebSocket-Key': websocket_key,

    'Sec-WebSocket-Version': '13',

    'Upgrade': 'websocket',

    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/111.0.0.0 Safari/537.36' ,  

}

ws = websocket.create_connection(

    f"wss://{host}/app/", sslopt={"cert_reqs": ssl.CERT_NONE},

    header=header,

    http_proxy_port=proxy_port,

    http_proxy_host = proxy_host,

    proxy_type="http",

    http_proxy_auth=(usr, pswd)

    )

ws.send(json.dumps({

    "handle": -1,

    "method": "GetDocList",

    "params": [],

    "outKey": -1,

    "id": 1

}))

result = ws.recv()

while result:

    result=ws.recv()

    y = json.loads(result)

    print(y)

ws.close()



since I can't move forward, I first copied the header from my browser (when I access api engine). I don't think this is the best way to do it but this is what I use to start
