Explaination

I'm trying to access an API call of a website with AJAX Authentication. Hence I log in to the website using username and password and the is login_url(AJAX API URL). Then trying to use the cookies of login response for my next API request. As you have seen in the code in the next I'm using the cookie of login response as the header for the next API call.

I hope someone could help me to identify the issue in my request.

For reference my code is

from requests import Session
import requests
class Login:
  
    def sendRequestWithAuthentication(self,loginDetails,requestDetails):
        user_agent = {'User-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.129 Safari/537.36'}
        action_url=loginDetails['action_url'] if 'action_url' in loginDetails.keys() else None
        pay_load=loginDetails['login_details'] if 'login_details' in loginDetails.keys() else None
        session_requests = requests.session()
        if action_url and pay_load:         
            act_resp=session_requests.post(action_url, data=pay_load, headers=user_agent)
            auth_cookies=act_resp.cookies.get_dict()
            url,method,request_payload = requestDetails['url'],requestDetails['method'],requestDetails['payload']
            querystring=requestDetails['querystring']
            headers={**user_agent,**requestDetails['headers']}
            if method == 'GET' or method == 'get':
               response=session_requests.get(url,headers=headers,cookies=auth_cookies,data=request_payload,params=querystring)
            elif method == 'POST' or method == 'post':
               response=session_requests.get(url,headers=headers,cookies=auth_cookies,data=request_payload,params=querystring)
        return response.json()

For this, I'm getting the following error

UPDATE

The website login is done through multi factor authentication

回答1:

I think the first issue that you should address is that requests won't trust the cert of that site, like the last error line states. Maybe try to add the cert first. Check here for how to set the cert. Sorry for the short answer. I would've written a comment, but I'm still new and am therefore not allowed to comment.
