I'm looking something which could be interesting to you as well. I'm developing a feature using Python, which should be able to authenticate (using userid/password and/or with other preferred authentication methods) and connect to specify website, navigate through the website and download the file under a specific option. Later I have to write the schedules on developed code and automate it.

Did anyone come across such scenario and developed the code in python? Please suggest if any python libraries are there.

What I have achieved right now is:

I can download file with specific URL.

I know how to authenticate and download the file.

I'm able to pull the links from the specific website.

This is something we could achieve using selenium, but I want to write in Python.

After 5 days of research, I found what I wanted. Your urlLogin and urlAuth could be same, its totally depends on what action taken on Login button or form action. I used crome inspect option to findout the actual GET or POST request used on the portal.

Here is the answer of my own question-->

import requestsurlLogin = 'https://example.com/jsp/login.jsp'
urlAuth = 'https://example.com/CheckLoginServlet'
urlBd = 'https://example.com/jsp/batchdownload.jsp'
payload = {"username": "username","password": "password"
}# Session will be closed at the end of with block
with requests.Session() as s:s.get(urlLogin)headers = s.cookies.get_dict()print(f"Session cookies {headers}")r1 = s.post(urlAuth, data=payload, headers=headers)print(f'MainFrame text:::: {r1.status_code}')  #200r2 = s.post(urlBd, data=payload)print(f'MainFrame text:::: {r2.status_code}')  #200print(f'MainFrame text:::: {r2.text}')  #page source# 3. Again cookies will be used through session to access batch download pager2 = s.post(config['access-url'])print(f'Batch Download status:::: {r2.status_code}')  #200source_code = r2.text# print(f'Batch Download source:::: {source_code}')
