Here's a small Flask app authenticated with Flask-HTTPAuth.

How to pass an argument (such as authentication on/off flag, or verbosity level / debug on/off flag) to a function (such as authenticate below) decorated with @auth.verify_password (without raising an error)?

Current code:

auth = HTTPBasicAuth()authorized_users_dict = [..]# [..]@auth.verify_password
def authenticate(username, password):    if username in authorized_users_dict:if check_password_hash(pwhash=authorized_users_dict[username], password=password):return True# [..]# [..]@auth.login_required()# [..]

I don't think passing this dictionary as an argument is the best choice. I assume this dictionary is fixed, so there is actually no technical reason to pass it as an argument every single time there is an incoming request.

But, if you feel strongly about it, one way to do it is with the partial function from the Python standard library. Something like this:

from functools import partialauthorized_users_dict = [..]def authenticate(users_dict, username, password):    if username in users_dict:# ...auth.login_required(partial(authenticate, authorized_users_dict))
