The 'action' URL will not be followed automatically by wget, it is filtered out 
by purpose. Libwget should parse it, maybe wget2 does not filter it out right 
now - but this should be fixed.

Basically you need to parse HTML for more infos - the library contains a 
scanner and example code to use it. If you want to go that way, you need some 
knowledge/background about the HTML form mechanism (as Dale pointed out).

If you just have one use case, take a browser's 'development' tools (Firefox 
and Chromium have those), fill in your form as usual and just see what is 
transferred to the server. You can then set header lines and content via wget.
Cookies normally play a role when it comes to login/authentication.
