Authentication doesn't work when opening app with pathname

daveishere · November 13, 2017, 3:29pm

I am using the dcc.Location component to open my dashboards with certain data already populated. I am now attempting to add authentication to the process. The problem I have is that if I open the dashboard with a pathname in the URL then I receive a 403 error rather than the login popup/screen. This happens with both the Basic auth and the Plotly auth.

Any idea for how to work around this? Or whether the authentication process can be changed to allow it?

I am also having this problem.
Did you ever find out what the issue was?

I suspect that its due to the fact that the base Auth class works by rewriting the index page; if that never happens, then the auth is never fired. See here:

github.com

plotly/dash-auth/blob/master/dash_auth/auth.py

from __future__ import absolute_import
from abc import ABCMeta, abstractmethod
from six import iteritems, add_metaclass


@add_metaclass(ABCMeta)
class Auth(object):
    def __init__(self, app):
        self.app = app
        self._index_view_name = app.config['routes_pathname_prefix']
        self._overwrite_index()
        self._protect_views()
        self._index_view_name = app.config['routes_pathname_prefix']

    def _overwrite_index(self):
        original_index = self.app.server.view_functions[self._index_view_name]

        def wrap_index(*args, **kwargs):
            if self.is_authorized():
                return original_index(*args, **kwargs)
