Lift-Omniauth Module

Usage

in Boot.scala

import omniauth.lib._
...
//Add Omniauth to the sitemap
Omniauth.sitemap
//init
//Supply a list of providers
Omniauth.initWithProviders(List(new FacebookProvider("key", "secret")))
//or init with providers in properties
OmniauthLib.init

in your properties file define your client id (key) and secret for each provider you will use

omniauth.facebooksecret=...
omniauth.facebookkey=...

For Facebook provider you can set permissions. For example:

omniauth.facebookpermissions=email,read_stream    

After a user has logged into an auth provider you can access data through the session var OmniauthLib.currentAuthMap

OmniauthLib.currentAuthMap match {
  case Full(omni) => ({
    println(omni.get(OmniauthLib.Provider))
    println(omni.get(OmniauthLib.UID))
    println(omni.get(OmniauthLib.UserInfo))
  })
}

You can also use obtain a user's unique ID from a provider without using sessions using Omniauth.tokenToId(provider:String, token:String): Box[String]

Omniauth.tokenToId("facebook", token) match {
  case Full(uid) => user.doSomethingWithFacebookId(uid)
}
