User login on a website using Shibboleth without a browser

Hmmm.

You need to be aware, if you are not already that Shibboleth SP and IdP and both implementations (_Very_ complete implementations) of a several standardized profiles based upon several standardized protocols and formats.

Screen scraping and reverse engineering that is going to be painful and fragile.

You need to research SAML fully (There's some stuff in Wikipedia which AIUI were heavily edited by one of the contributors to this list) and read and understand the standards (they are all up on oasis-open.org)  Use a Shibboleth SP and IdP to help your understanding.  If you really want a non-browser profile you need to consider ECP.

Armed with that you will know the answer to most of your questions, but it is a learning cliff.

But we are sort of jumping to an implementation question ("gluing wings on a pig").  What are you trying to achieve?
