Question

我目前正在使用CakePHP 2.4.5并尝试实施授权。我的AppController.php是：

class AppController extends Controller {
    public $helpers = array('Html', 'Form', 'Session');
    public $components = array(
        'Session',
        'RequestHandler',

        'Auth' => array(
            'loginRedirect' => array(
                'controller' => 'themeroles',
                'action' => 'add'
            ),
            'logoutRedirect' => array(
                'controller' => 'pages',
                'action' => 'display',
                'home'
            )
        )   
    );

    public function isAuthorized($user) {
        $auth = CakeSession::read('Auth');
        if (isset($auth['User'])){ 
            $loggedInUser = $auth['User']['username'];
            $loggedInRole = $auth['User']['role'];
            // Admin can access every action
            if (isset($loggedInRole) && $loggedInRole === 'admin') {
                return true;
            }
            if (isset($loggedInUser) &&!empty($user) && $loggedInUser === $user) {
                return true;
            }
        }

        CakeSession::write('redirectURL', Router::reverse($this->request, true));
        // Default deny
        return false;
    }

    public function beforeFilter() {
        $this->Auth->allow('index', 'view');
    }

}

我的UsersController有：

public function beforeFilter() {

    parent::beforeFilter();
    $this->Auth->allow('add', 'logout');
}

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

但重定向后，似乎会话被杀死了。我自动被重定向到登录页面。

我发现可以在core.php中设置解决方案：

Configure::write('Security.level', 'low');
Configure::write('Security.cookie', 'cakephpfdebackend');
Configure::write('Session.cookieTimeout', 0);
Configure::write('Session.checkAgent', false);
Configure::write('Session.cookie_secure',false);
Configure::write('Session.referer_check' ,false);
Configure::write('Session.defaults', 'php');

但这没有用。我错过了什么？

我认为问题出在你的isAuthorized()函数上。在每次尝试登录时编写新会话之前，它会发现isset($auth['User'])已设置但为空。因此，if都不会运行。结果它返回false。

所以，试试：

if (!empty($auth['User'])){

重定向后会话丢失在cakePhp 2.4中登录
