How the omniauth gem create the routes?

I am using the omniauth to implement the authentication strategy, but there is one thing I cannot understand: The omniauth would generate some routes to use but I cannot see it by rake routes.

For example, the gem omniauth-saml will generate the auth/saml routes, when I visit this path, It will initiate the request phase. However, I cannot find it on the routes list. Therefore, it's hard for me to know which routes have already been created and could be used directly.

Could anyone help me?

Cheers

  • I have found the answer.

    Omniauth is a rack based application, so it can handle every HTTP request and do the tasks based on different path. They call the task phase.

    It includes two mainly phases:

    request phase: Default path is "#{path_prefix}/#{name}"

    callback phase: Default path is "#{path_prefix}/#{name}/callback, customise by options[:callback_path]
