Goldfinger, a WebFinger client for Ruby

A WebFinger client for Ruby. Supports application/xrd+xml and application/jrd+json responses. Raises Goldfinger::NotFoundError on failure to fetch the Webfinger or XRD data, can also raise HTTP:Error or OpenSSL::SSL::SSLError if something is wrong with the HTTPS connection it uses.

• Does not fall back to HTTP if HTTPS is not available
• Does check host-meta XRD, but only if the standard WebFinger path yielded no result

gem install goldfinger

data = Goldfinger.finger('acct:gargron@quitter.no')

data.link('http://schemas.google.com/g/2010#updates-from').href
# => "https://quitter.no/api/statuses/user_timeline/7477.atom"

data.aliases
# => ["https://quitter.no/user/7477", "https://quitter.no/gargron"]

data.subject
# => "acct:gargron@quitter.no"

The official WebFinger RFC is 7033.
