How can I connect to Google using oauth with Ruby?

问题:

there are oauth and oauth2 gems, but I have not found an example to connect to google with oauth

回答1:

The officially supported method is to use Signet. The README contains the example code required to authenticate against the Google OAuth endpoints. See also the Google API Client for Ruby. If you have any questions on either, don't hesitate to ping me. I'm supporting both libraries.

Signet will also work for other OAuth providers. An official OmniAuth plugin is also available.

回答2:

Try omniauth instead.
