How to maintain the session login status?

To maintain the user’s login status, you can use the following methods:

1. Using cookies: After a successful login, the server generates a cookie containing user information and sends it to the client’s browser. The client will then carry this cookie in every subsequent request, allowing the server to maintain the user’s login status by verifying the user information in the cookie.
2. By using sessions, the server can create a unique session identifier for each user and send it to the client. The client will carry this session identifier with them in each request, allowing the server to maintain the user’s login status based on the information in the identifier.
3. Token usage: After a user successfully logs in, the server generates a token containing user information and sends it to the client. The client will then carry this token in each subsequent request, allowing the server to maintain the user’s login status by validating the user information within the token. This method is commonly used for building stateless APIs.

Regardless of the method used, the server side needs to verify and protect the user’s login information to ensure their security.
