Anyone has experience for manually set authentication request to keycloak?

I want to write a script to manually set authentication request to keycloak.
this is the request I got for login:
/auth/realms/pangu/login-actions/authenticate?session_code=k7nJnICEaDDaHuaWGJIb37_M_ZZggsW9uDjT3DBTvY1&execution=40c18847-1e5d-4399-8927-8c67a3e7dcc1&client_id=zulip&tab_id=Ld3eo2eikk1
form data:
username:
password:

where does the session_code, execution and tab_id come from ?

hi @lixiran
Have you found the solution for this questions ?

I believe you are trying to do the login with a HTTP POST request.
