Class SampleAuthorizationClient

java.lang.Object

com.avaya.collaboration.authorization.sample.SampleAuthorizationClient

public final class SampleAuthorizationClient
extends Object

 
  Sample code to get an access token using AuthorizationClientHelper. 

  
  Use AuthorizationClientHelper.getAccessToken() to obtain an AccessToken for a client.

  Use AuthorizationClientHelper.getAccessTokenForUser(userName, userPass) to obtain an AccessToken for a user. 

  
  AccessToken.toString() returns the token string.
  AccessToken.getExpiresIn() returns the token's expiry in seconds. This can be used to cache the token for a specific lease time.

  AccessToken.getScopes() returns a list of scopes associated with the token.
