CAS SSO transformation steps (1)

According to the company's business needs, a single sign-on server needs to be configured to provide a unified authentication center for subsequent application launches.

The required services are as follows:

1. sign in
2. Only one place to log in at a time
3. Each user can only access authorized applications
4. Login log

The simplified versions of several main database tables are recorded as follows.

USERS

ID	WHERE
EMAIL	WHERE
PASSWORD	WHERE
TOKEN	WHERE

The token here is mainly used as a token that can only be logged in one place at a time. This token sets the login status to "1" when logging in, and will change the login status to "0" when logging out or closing the browser or when the TGC ticket becomes invalid.

USER_LOGGED_LOG

ID	WHERE
USER_ID	WHERE
IP	WHERE
LOGGED_TIME	TIME

This table mainly records user login logs.

APPLICATIONS

ID	WHERE
URL	WHERE
APP_NAME	WHERE

Mainly record the link and name of each application.

USER_APPS

ID	WHERE
USER_ID	WHERE
APP_ID	WHERE

Authorized application corresponding to each user.

The above is the database table designed to realize the main functions. The transformation of the cas part continues below.
