EOAUTH how to use AccessToken

I’ve installed EOAUTH extension, i can authenticate with google, but I’m wondering how to get user information after that.

here’s what I do in login method of user controller:


Yii::import('ext.eoauth.*');

		

		$ui = new EOAuthUserIdentity(

				array(

				//Set the "scope" to the service you want to use

						'scope'=>'https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile',

						'provider'=>array(

								'request'=>'https://www.google.com/accounts/OAuthGetRequestToken',

								'authorize'=>'https://www.google.com/accounts/OAuthAuthorizeToken',

								'access'=>'https://www.google.com/accounts/OAuthGetAccessToken',

						)

				)

		);

		

		if ($ui->authenticate()) {

			$user=Yii::app()->user;

			$user->login($ui);

			$this->redirect(array('loggedin'));

		}

		else 

			throw new CHttpException(401, $ui->error);

		



any help would be appreciated.
