After some additional sleuthing I realized I wasn't passing the
'Authorization' header with the contents API request. Thinking this might be
the problem I added the header, but then got the following response in the
console running jupyterhub:

Subject: Emacs IPython Notebook and Jupyterhub
Getting EIN working with Jupyterhub has been a long standing request, and I
have been trying to get this implemented the past couple days. Unfortunately
I've come against a wall and wonder if someone here might be able to provide
some guidance.
At the moment I am using the REST API as documented on the website
(https://jupyterhub.readthedocs.io/en/latest/_static/rest-api/index.html)
and things go pretty well, up to a certain point. Here is the sequence of
events I have programmed:
1. After supplying a url, user name, and password, ein sends a query to
'/hub/api/authorizations/token'.
2. We store the token, make sure the Authorization header looks like the
example code at (https://jupyterhub.readthedocs.io/en/latest/rest.html) then
query '/hub/api/user/[user]/server' to start a notebook server.
3. EIN queries '/hub/api/user/[user]' to get information about this user,
most importantly we are looking for the server path for the newly started
server.
4. Use the server path to use EIN's usual facilities for accessing the
notebook server.
Things work great up until step 4. EIN will try querying, as an example,
'http://127.0.0.1:8000/user/millejoh/api/contents' and Jupyterhub will
respond by redirecting to the hub login page. Interestingly enough a call to
'http://127.0.0.1:8000/user/millejoh/api' works as expected, that is it will
return JSON with the version of the running notebook server.
Apparently authenticating via '/hub/api/authentications/token' doesn't
really authenticate, at least as far as access to the contents API is
concerned? Is there something else EIN needs to be doing to ingratiate
itself to jupyterhub and convince the hub it really is a nice guy/gal and
promises to play nice with everyone?
Best regards,
John
