Flask-JWT-Extended breaks compatibility

[JulienPalard]

Quick fix is to use Flask-JWT-Extended<4 in the requirements/prod.txt but maybe someone want to port flask-realworld-example-app to Flask-JWT-Extended 4?

3 important points to fix from source cde
1, @jwt_optional==>@@jwt_required(optional=True)
2, @jwt_required==>@jwt_required()
3, change jwt_identity take 2 pars:

def jwt_identity(jwt_header, jwt_payload):
    identity = jwt_payload["sub"]
    return User.query.filter_by(id=identity).one_or_none()
