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
