Get sessionId using request Python

Question

I'm trying to get the sessionId, so i can do other requests.
So i looked in the Firefox Network monitor (Ctrl+Shift+Q) and saw this:

So i wondered how i could do the request in python 3 and tried things like this:

import requests
payload = {'uid' : 'username',
      'pwd' : 'password'}

r = requests.get(r'http://192.168.2.114(cgi-bin/wwwugw.cgi', data=payload)

print r.text

But I always get "Response [400]".
If the request is correct, I should get something like this:

Thanks
Alex

It should be requests.post. and you have to pass every item using the same format.meaning, you have to include method, params parts as well. also make sure to enter the correct url. the one in your question has a typo. — Himal

@Himal so I did enter the method param aswell and now i'm getting Errno 133 (payload = {'method':'ugw-login', 'params':{'uid' : 'gw', 'pwd' : 'GATEWAY'}}) — Alex

Could you please update your question to include the latest version of the code you have and the complete error message you are getting ? — Himal

Also, can you see any cookies being sent on that POST request ? Additionally, you might have to include other request headers such as "Referer". you can test it by removing one of the headers and posting it again (using the tool you used on your first image) . do this with every header. — Himal

Just use a session, which will handle redirects and cookies for you:

import requests
payload = {'uid' : 'username',
          'pwd' : 'password'}

with requests.Session() as session:
    r = session.post(r'http://192.168.2.114(cgi-bin/wwwugw.cgi', data=payload)

    print(r.json)

This way you don't explicitly need to get the sessionId, but if you still want to, you can access the returned JSON as a dictionary.

if you want to get the Session ID you can use Session() from the requests library:

URL = "Some URL here"

client = requests.Session()
client.get(URL)
client.cookies['sessionid']

In requests 2.32.4 this results in a KeyError exception

Although it's not very clear from your question, but I've noticed few issues with what you are trying to accomplish.

If you are using session authentication, then you are suppose the send session_id as a Cookie header, which you aren't doing.
400 response code means bad request, not authentication required. Why are you sending data in get request to begin with? There's a difference between data and query params.

Yeah all of us commit mistakes like that. You need to frame your question a little better though.
