Überauth Khan Academy

Khan Academy strategy for Überauth.

Note: Sessions are required for this strategy.

Source code is available on Github.

Installation

1. Create an application at Flickr App Garden.

2. Add :ueberauth_flickr to your list of dependencies in mix.exs:

   def deps do
     [{:ueberauth_flicker, "~> 0.2"}]
   end
   

3. Add the strategy to your applications:

   def application do
     [applications: [:ueberauth_flickr]]
   end
   

4. Add Flickr to your Überauth configuration:

   config :ueberauth, Ueberauth,
     providers: [
       flickr: {Ueberauth.Strategy.Flickr, []}
     ]
   

5. Update your provider configuration:

   config :ueberauth, Ueberauth.Strategy.Flickr.OAuth,
     consumer_key: System.get_env("FLICKR_CONSUMER_KEY"),
     consumer_secret: System.get_env("FLICKR_CONSUMER_SECRET")
   

6. Include the Überauth plug in your controller:

   defmodule MyApp.AuthController do
     use MyApp.Web, :controller
   
     pipeline :browser do
       plug Ueberauth
       ...
      end
   end
   

7. Create the request and callback routes if you haven't already:

   scope "/auth", MyApp do
     pipe_through :browser
   
     get "/:provider", AuthController, :request
     get "/:provider/callback", AuthController, :callback
   end
   

8. Your controller needs to implement callbacks to deal with Ueberauth.Auth and Ueberauth.Failure responses.

For an example implementation see the Überauth Example application.

Calling

Depending on the configured url you can initial the request through:

/auth/flickr

Or with options:

/auth/flickr?perms=delete

By default the permissions are the ones defined in your application authentication flow on Flickr. To override them, set a perms query value on the request path or in your configuration. Allowed values are "read", "write", or "delete".

config :ueberauth, Ueberauth,
  providers: [
    flickr: {Ueberauth.Strategy.Flickr, [default_perms: "delete"]}
  ]
