gunicorn 和 flask-jwt-extended 没有获得当前用户

Question

I've been building an app that uses flask, flask_jwt_extended and the decorator @jwt_required around protected functions that need an access token to access. From these endpoints, I can use flask_jwt_extended 's get_current_user function to fetch the currrent user.

This has been working fine while in development, but now I'm planning to serve a production application using gunicorn . However, when I run the gunicorn server, it seems like the get_current_user function is always returning none. For example, the following code works with python3 -m flask run , but not with gunicorn run:app -b localhost:5000 . What could be the problem here?

@jwt_required
def get_user_by_id(user_id: str) -> Dict[str, Any]:
    # returns user when using flask run, but not with gunicorn
    curr_user = get_current_user()

Class-worker

• Do you use multiple workers and sync class ? Maybe try to look at gunicorn worker-class

If you try to use the sync worker type and set the threads setting to more than 1, the gthread worker type will be used instead.

• In your python configuration file or you can change worker-class directly in the command line.

worker_class = 'gthread'

Check your JWT_SECRET_KEY

• JWT_SECRET_KEY need to have the same value all over each workers
