Yii 封存 登录用户信息

Yii 保存 登录用户信息
class UserIdentity extends CUserIdentity{ public $user; public function authenticate() { $this->errorCode=self::ERROR_PASSWORD_INVALID; $user=Member::model()->findByAttributes(array('userid'=>CHtml::encode($this->username))); if ($user) { if ($user->passwd === md5($this->password)) { $this->errorCode=self::ERROR_NONE; $this->setUser($user); } } unset($user); return !$this->errorCode; } public function getUser() { return $this->user; } public function setUser(CActiveRecord $user) { $this->user=$user->attributes; } }?然后创建：protected/components/WebUser.php?继承CWebUser类

class WebUser extends CWebUser{    public function __get($name)    {        if ($this->hasState('__userInfo')) {            $user=$this->getState('__userInfo',array());            if (isset($user[$name])) {                return $user[$name];            }        }         return parent::__get($name);    }     public function login($identity, $duration=0) {        $this->setState('__userInfo', $identity->getUser());        parent::login($identity, $duration);    }}

 'user'=>array( //user（用户）组件配置，“user”为组件ID            'class'=>'WebUser',//使用WebUser类            // 可以使用基于cookie 的认证     'allowAutoLogin'=>true,//允许自动登录            'stateKeyPrefix'=>'zgsx', //session前缀  ),
