Google App Engine Python Authentication from API

I'm currently building a Python webapp on the Google App Engine and I want to expose various parts of my application via a JSON API. This API may be used in the form of a mobile client, or (for the purposes of testing) a headless Python script.

I need to be able to authenticate users before they perform operations on the API. I notice that the Users API does not support simple authentication [in the form of authenticate(username, password)] so merely sending the username/password to a URL and then later using some given token would not work.

Ultimately, I would like the application to use Facebook Connect in addition to its own logins.

Could somebody please suggest how is the best way to authenticate users in this situati开发者_JAVA技巧on, using a remote JSON API and the Google App Engine?

Cheers

You might want to check out the recently released oauth support. Failing that, you can implement your own authentication, for example by using simple or digest authentication.

Just for the record, I ended up going with the wonderful Tipfy framework in the end.
