However, when a token is blacklisted, it is also persisted to the database.\n\n### Why\n\n* Emulate a redis store without actually using redis! \ud83d\udc4d\n    * This is almost certainly slower than redis (It's python, after all).\n* Why not, it's an excuse to get to know flask and associated libraries a little bit better. \ud83d\udc4d\n\n### How\nYou *are* using a [virtualenv](https://virtualenv.pypa.io/en/latest/), right?\n\n`pip install flask-blacklist` \n\n\nThen in your app factory function, initialize `Blacklist` *after* you've initialized your ORM.\n\n    # In global scope\n    from flask_blacklist import Blacklist, is_blacklisted\n    db = SQLAlchemy()\n    guard = Praetorian()\n    bl = Blacklist()\n\n    # In the app factory function\n    app = Flask(__name__)\n    db.init_app(app)\n\n    from app.models import Token, User\n    bl.init_app(app, Token) # Initialize after your ORM\n\n    # is_blacklisted is a helper function that Praetorian uses to determine if a token has been blacklisted\n    guard.init_app(app, User, is_blacklisted)  \n\nThe Token database model needs to have two different class methods:\n\n* `Token.blacklist_jti` \n    * Takes a single parameter, which is the `jti` string extracted from a JWT\n    * This method calll persist the blacklisted `jti` string to your database.\n* `Token.get_blacklisted` \n    * Should return a list of already blacklisted tokens from the database\n    * The tokens returns should have a `jti` attribute containing string extracted from the token you want to blacklist\n\nThen, in the route that needs to invalidate the token:\n\n    @auth_blueprint.route(\"/v1/auth/token\", methods=[\"DELETE\"])\n    @auth_required\n    def invalidate_token():\n        token = guard.read_token_from_header()\n        jti = guard.extract_jwt_token(token)[\"jti\"]\n        bl.blacklist_jti(jti)\n        rv, code = {\"success\": True, \"message\": \"token invalidated\"}, 200\n        return jsonify(rv), code\n\n<hr>\n\nCopyright 2019 Alexander Potts, MIT license.\n\n\n",
