Dave Johnson on open web technologies, social software and software development
Over the past month or so I've been adding OAuth support to just about every open source project that I can commit to. I added OAuth support to Roller so that you can now use OAuth to protect Roller's AtomPub server and other things. I also added OAuth support to ROME Propono's AtomPub client so you can now use Propono to post to Roller (more about that later). Here's a quick overview of how OAuth in Roller works.
NOTE that this post applies to Roller 5.0, which has not yet been officially released.
If you want to use OAuth with AtomPub on your Roller site, go to the Server Admin page and find the Web Services section, enable AtomPub and specify 'oauth' as the authentication mechanism, like so:
Once you've done the setup, you'll find an OAuth Credentials link on the Roller Main Menu page, which will lead you a page like the one below showing your OAuth consumer key & secret and, if you are a site admin user, the site-wide key & secret. Currently, there's only one set of site-wide credentials; I plan to fix that.
Of course, those aren't my real keys. You'll want to keep your OAuth keys secret as they can enable anybody to access your Roller account via AtomPub.
I mentioned that Roller 5.0 has not yet been released and that's true. There's still a lot of work to be done on 5.0, but that doesn't mean you can't get your hands on the code and binaries now. To make it easy, I've made an unofficial snapshot version of Roller 5.0-dev available for testing purposes only. It's what I'm running on my site. You can get it here in two flavors:
The instructions in the old Roller 4.0 installation guide should work fine, so follow them to install and configure the 5.0-dev SNAPSHOT. Please send questions and feedback to either the Roller dev mail list and I'll do my best to respond there.
You'll also need an OAuth capable AtomPub client. More on that topic tomorrow...
