Get OAuth 2.0 working in Drupal 7

Attached is the beginnings of a patch. It removes the compile time errors from trying to use OAuth2HTTPSFetcher, but I still haven't been able to get the module to work. I may look for a different solution rather than trying to fix this module.

Ok, I've managed to get OAuth 2.0 working minimally against the Google OAuth 2.0 implementation. There are still a bunch of things to implement (namely, using the refresh_token to refresh expired keys) and clean-up, but it works!

This patch is finally ready for review! The latest version will refresh the access token automatically when it expires and it makes minor updates to the OAuth 1.0 support for the changes I made to the DB and API (although I haven't tested it).

I'm using this to make authenticated requests to the YouTube API. In that API, when pulling a video feed, it won't give you the tags unless you are authenticated as the user who owns the video.

I'm using Feeds: YouTube Parser to actually parse the YouTube specific data out of the Atom. Here is the issue in the queue over there: #1880326: can't import youtube keyword tags (add information about feeds_oauth to the docs!)

To actually test that scenerio, you'll need an account on YouTube, with at least one video with some tags on it.

The feed URL will look like:

https://gdata.youtube.com/feeds/api/users/username/uploads?v=2

... except with username replaced by your actual YouTube username.

If you create an importer which uses the "HTTP Fetcher", "YouTube parser", "Node processor" and maps "Tags" to a taxonomy field, you'll notice that it never adds any tags!

To do OAuth 2.0, you'll need to create a project with access to the "YouTube Data API" and add a "Client ID for web applications" in the Google APIs Console: https://code.google.com/apis/console

Use the "HTTPS OAuth 2.0 Fetcher" with the following settings:

• Site identifier: (can be anything!)
• Consumer key: (must match the "Client ID" from the Google APIs Console)
• Consumer secret: (must match the "Client secret" from the Google APIs Console)
• Access token URL: https://accounts.google.com/o/oauth2/token
• Authorize URL: https://accounts.google.com/o/oauth2/auth
• Scope: https://gdata.youtube.com

Now when you run the import, you should notice that your taxonomy field will get filled with the tags from the YouTube videos!

Sorry for having such a complicated scenerio, but it's what I've been working with. :-)

Oh, and I forgot to add that after you apply the patch you need to run update.php or drush updatedb because it makes changes to the database schema.

Ah, yeah, sorry - I'm using the 2.x-dev version of feeds_youtube, I had completely forgotten about that. :-)

Awesome! Thanks so much for taking the time to review and test the patch and get it committed so quickly. It always really feels great to spend a couple days hacking on something and see it get accepted upstream - but I'm not sure I've ever experienced it happen so fast. :-)

Thanks for the offer! I would be interested in helping co-maintain Feeds OAuth, at least in the near term. I'd love to help get a full Drupal 7 release out.
