How can I implement advanced JWT usage in Flask?

To implement advanced JWT usage in Flask, you can use the Flask-JWT-Extended library. It allows for features like token refreshing, blacklisting, and custom claims.

Can you explain how to set up token refreshing?

Sure! You can set up token refreshing by creating a refresh token endpoint. Use the @jwt.refresh_token_required decorator to protect it and issue a new access token.

What about blacklisting tokens?

For blacklisting, you can use the JWT_BLACKLIST_ENABLED configuration. Store blacklisted tokens in a database or in-memory store and check against it during authentication.

How do I add custom claims to my JWT?

You can add custom claims by including them in the create_access_token function. Just pass a additional_claims parameter with your custom data.
