CAS Authentication Module

User Entry Point

Users trigger CAS login in the Ham app via:

Me → Manage Info Portal settings → Login / Re-login

When using education features (course query, grade query, etc.) for the first time without a portal login, the app guides users to the CAS login page.

Features

CAS (Central Authentication Service) is the university's unified identity authentication system. The Ham React Native Components CAS module handles:

1. Loading the university CAS login page via WebView
2. Injecting custom JavaScript scripts for login form localization (multi-language support)
3. Intercepting cookies after successful login
4. Passing cookies back to the native side for subsequent education system requests
