php - 登录 WebUser 返回 FALSE

Question

Yii::app()->user->login返回FALSE。

这怎么会返回 FALSE，为什么？

代码：

public function login()
{
    if($this->_identity===null)
    {
        $this->_identity = new UserIdentity($this->username,$this->password);
        $this->_identity->authenticate();
    }


    if($this->_identity->errorCode===UserIdentity::ERROR_NONE)
    {
        $duration=$this->rememberMe ? 3600*24*30 : 0; // 30 days
        $r2 = Yii::app()->user->login($this->_identity,$duration);
  MyLog::log("res r: ".var_export($r2, true));
        return true;
    }
    else
        return false;
}

CWebUser->login() does not return anything

Yii::app()->user->login($this->_identity, $duration) 

It will return null
