REST APIs with Flask and Python - Blacklisting with Flask-JWT-Extended

The video tutorial explains how to implement a blacklist in a Flask application using JWT extended. It covers creating a blacklist file with user IDs, configuring the application to enable blacklisting, and implementing a function to check if a token is blacklisted. The tutorial also demonstrates testing the blacklist functionality by creating users and checking access with tokens. It concludes with potential use cases for blacklisting, such as revoking access for abusive users or expired tokens.

What is the purpose of creating a blacklist in the context of this video?

• To enable access for all users

• To deny access to specific user IDs

• To allow access to specific user IDs

• To create a list of all user IDs

What configuration change is necessary to enable blacklisting in the application?

• Set JWT_blacklist_enabled to false

• Set JWT_blacklist_enabled to true

• Remove JWT_blacklist_enabled

• Set JWT_blacklist_enabled to null

What does the blacklist token check configuration do?

• Enables blacklist for refresh tokens only

• Enables blacklist for access tokens only

• Enables blacklist for both access and refresh tokens

• Disables blacklist for all tokens

What is the role of the function 'check if token in Blacklist'?

• To list all blacklisted tokens

• To verify if a token is in the blacklist

• To remove tokens from the blacklist

• To add tokens to the blacklist

What happens if a token is found in the blacklist?

• The token is revoked and access is denied

• The token is added to a whitelist

• The token is refreshed

• The token is ignored

What is a practical use of token revoking mentioned in the video?

• To allow access to all users

• To enable access for new users

• To revoke access for users who have logged out

• To create a list of all active tokens

Why might you want to revoke a token instead of a user ID?

• To allow the user to log in again

• To permanently block the user

• To refresh the user's session

• To enable access for all users
