Richard McIntyre has a new post to his blog showing how he set up OAuth support in a Lithium-based application with the help of a handy plugin (li3_oath).

The OAuth protocol is a fantastic way to login to remote services and websites. Unfortunately the spec is different in OAuth 1.0 and the yet un-solidified 2.0, the implementation is also different across different services. At the moment this is a bit of a goose chase, but libraries like li3_oauth can help! [...] I like to be in control and calling the shots! I also want to have users have the option to login to other services under the same umbrella. Working directly with OAuth is what I wanted to do. Of course I was doing this in Lithium because it is clearly the best PHP Framework!

His process is broken up into four steps:

• Grab the latest version of the li3_oauth plugin
• Fork and refactor the plugin
• Create the Tweet and Facebook controllers
• Refactor a bit more to turn it into a service

The code changes are pretty minimal and are included in the post.
