angularjs - How to access Devise_token_auth access token of omniauth provider? -

how access access token of omniauth provider should sent after successful authentication devise_token_auth gem , ng-token-auth angular? i'd store token make future requests omniauth provider updating information. omniauth provider strava. see devise_token_auth creating own access tokens, aren't accessing strava. have no idea devise token auth pulls in information strava after reading through gem's code. seems should pretty simple thing, can't 1 wants information returned. in advance.

we have been able figure out lot of experimentation. @resouce return nil too, did find access-token , other information returned omniauth provider, located in request.env['omniauth.auth'], located in redirect_callbacks action of omniauthcallbacks controller. needed set up

mount_devise_token_auth_for 'user', at: 'auth', controllers: { omniauth_callbacks: 'registrations'}

in routes.rb, , create custom controller named registrationscontroller.

so our block looked this

class registrationscontroller < devisetokenauth::omniauthcallbackscontroller      def redirect_callbacks         super         puts "redirect:"         puts request.env['omniauth.params']         puts "auth info"         puts request.env['omniauth.auth'].credentials['token']         puts "redirect end"         # create user_strava_key , save it.         @strava_token = request.env['omniauth.auth'].credentials['token']         userstravakey.create(key_secret: @strava_token)     end  end
