Authentication 当我尝试$this时->；认证->；user（），但当我添加id$this->；认证->；用户（'；id'；）它不'；它是空的

$this->Auth->user（'id'）始终为空 AppController代码：

<?php
 App::uses('AuthComponent', 'Controller/Component');
 App::uses('Controller', 'Controller');
 class AppController extends Controller {
//public $components = array('DebugKit.Toolbar','Session');
  public $components = array(
    'Acl',
    'Flash',
    'Auth' => array(
        'authorize' => array(
            'Actions' => 
       array('actionPath' => 'controllers','action'=>'index')
        )
    ),
    'Session'
);
public $helpers = array('Html', 'Form', 'Session');

public function beforeFilter() {
    //Configure AuthComponent
    $this->Auth->allow();
    $this->Auth->loginAction = array(
      'controller' => 'personnes',
      'action' => 'login'
    );
    $this->Auth->logoutRedirect = array(
      'controller' => 'personnes',
      'action' => 'login'
    );
    $this->Auth->loginRedirect = array(
      'controller' => 'biens',
      'action' => 'index'
    ); }}

bienscontroller

     public function index( ) {
     $this->Bien->recursive = 0;
      $this->paginate = array(
      'paramType' => 'querystring',
    'limit' => 5
        );
      $biens = $this->paginate('Bien');
      $this->set(compact('biens'));
    $user = $this->Auth->user('id');
    Debugger::dump($user);
     }

人员模型`

<?php
    App::uses('AuthComponent', 'Controller/Component');
     App::uses('AppModel', 'Model');
     class Personne extends AppModel {`
      public function beforeSave($options = array()) {
      $this->data['Personne']['mdp'] = 
      AuthComponent::password($this>data['Personne']['mdp']);
       return true;
       }

当我尝试$this->Auth->user（）时，它工作，但当我添加id$this->Auth->user（'id'）时，它不工作，它是空的使用
$this->Auth->user（）
？数组（（int）0=>数组（'Personne'=>数组（“登录”=>“****”、“id”=>“2”、“指定”=>“管理员”、“日期”=>“2016-03-16”、“地址”=>“rue”、“telFixe”=>“266666”、“telMobile1”=>“88888”、“telMobile2”=>“9999”、“电子邮件”=>）wahiba@gmail.com“，'mdp'=>'wah'，'LIENPHOTOPERNATIONS'=>'wah.jpg'，'idVille'=>'1'），'Ville'=>数组（'idVille'=>'1'、'nomVille'=>'Hammamet'、'lienImageVille'=>'c://--'、'affichableVille'=>true、'codePostalVille'=>'8050'、'idPays'=>'1'）、'bienspersone'=>array（）、'Bien'=>array（））那么它不应该是$this->Auth->user（0）['persone'['id']；？？？
<?php
    App::uses('AuthComponent', 'Controller/Component');
     App::uses('AppModel', 'Model');
     class Personne extends AppModel {`
      public function beforeSave($options = array()) {
      $this->data['Personne']['mdp'] = 
      AuthComponent::password($this>data['Personne']['mdp']);
       return true;
       }
