CakePHP身份验证重定向不工作

为了学习cakephp，我试图重现烹饪书中的简单身份验证示例

我的问题是，当我试图访问一个未经授权的页面时，我只得到一个空白页面，上面有蛋糕安装通知警告：请更改安全盐和密码种子的有效期

这是我的appcontroller代码

class AppController extends Controller {

public $components = array(
    'Session',
    'Auth' => array(
        'loginRedirect' => array('controller' => 'posts', 'action' => 'index'),
        'logoutRedirect' => array('controller' => 'pages', 'action' => 'display', 'home')
    ),
    'RequestHandler'
);

public function beforeFilter() {
    $this->Auth->allow('index', 'view', 'login');
    $this->Auth->authorize = 'actions';
    $this->Auth->autoRedirect   = true;
}

public function beforeFilter() {
        parent::beforeFilter();
        $this->Auth->allow('add');
    }

    public function login() {
        echo "i am called";
        if ($this->request->is('post')) {
            if ($this->Auth->login()) {
                $this->redirect($this->Auth->redirect());
            } else {
                $this->Session->setFlash(__('Invalid username or password, try again'));
            }
        }
    }

    public function logout() {
        $this->redirect($this->Auth->logout());
    }

} 这是我的usercontroller代码

class AppController extends Controller {

public $components = array(
    'Session',
    'Auth' => array(
        'loginRedirect' => array('controller' => 'posts', 'action' => 'index'),
        'logoutRedirect' => array('controller' => 'pages', 'action' => 'display', 'home')
    ),
    'RequestHandler'
);

public function beforeFilter() {
    $this->Auth->allow('index', 'view', 'login');
    $this->Auth->authorize = 'actions';
    $this->Auth->autoRedirect   = true;
}

public function beforeFilter() {
        parent::beforeFilter();
        $this->Auth->allow('add');
    }

    public function login() {
        echo "i am called";
        if ($this->request->is('post')) {
            if ($this->Auth->login()) {
                $this->redirect($this->Auth->redirect());
            } else {
                $this->Session->setFlash(__('Invalid username or password, try again'));
            }
        }
    }

    public function logout() {
        $this->redirect($this->Auth->logout());
    }

是否有我没有做过的配置，或者对auth实现有任何误解

我使用Windows的EasyPHP作为我的Web服务器，但我也有一个关于安装PHP5、MySQL和Apache 2

密码和盐的问题，在App/CONFIG/COR.PHP中发现，当你看到空白页时，你必须在浏览器的URL栏中改变它们

，地址是什么？错误告诉你改变密码和盐。这样做。我不知道cakePHP默认通知消息可能会导致错误，但这解决了它，谢谢！！！
