How to write a parser for a site on which access authorization is implemented through google?

Question

Google

There is a site that can only be accessed by logging in through google. I need to programmatically get content from this site by logging in myself. I tried to parse through the curl, but Google has a redirect on the redirect, got confused at the end ((
Maybe where there are examples of the source code?
ps The programming language does not play a role.

Answer 1

You can do this with 'curl' for this you need
1. Know what POST-GET arguments the authorization page requires (the page where it goes after clicking on the button) and what arguments it might be 'login', 'pass'
2. Some written code
3. I did not work with Google authorization and did not understand what you mean at all.
