[google-appengine] Python script Google Authentication for a GAE Application

[Michael Byrd]

Hi Everyone,

I'm having a hard time figuring this out and I'm hoping someone can
point me in the right direction for what to read.

I've written an appengine app, a servlett, that will accept data from
a get request, check if the user is signed in to a google account and
then store the data from the request in the datastore (with a User as
part of the model). All pretty standard.

I'd like for a python script to be able to automate the data input
(think returning the results of seti@home) but it's important that the
python client be able to authenticate itself via a google account.

I'm at a bit of a loss for where to even start... these seem like good
places, but I don't even know enough to be sure which, if any, will
work:

http://code.google.com/apis/accounts/docs/OAuthForInstalledApps.html
-- seems like the best shot but they say as a log in for 'one or more
google service' which I'm not sure my app counts as..

http://code.google.com/appengine/docs/python/tools/uploadingdata.html
-- I think this is not so good as I would have to give every user too
lenient permissions for my app

I've looked through the gdata source code as well trying to
authenticate with a generic service, but I'm not sure if gdata
authentication is universal enough to work with an arbitrary appengine
app.

Ideally if someone can get me started or point me at the correct place
that would be great.

I'd rather not do this over email or xmpp, but I'm considering those
options.

Thank you anyone for your help!,
Michael

Hi Michael,

The appengine_rpc module from the SDK handles all this: http://code.google.com/p/googleappengine/source/browse/trunk/python/google/appengine/tools/appengine_rpc.py

You can use it directly in your app, and let it take care of authentication to an App Engine application.

That is exactly what I was looking for. In retrospect, looking
through the SDK probably should have come sooner. I'll do that in
the future.

Thank you very much, Nick.
