Zend Auth并在登录后重定向用户

所以我使用简单的Zend_Auth机制来确保我的用户在访问某些控制器之前登录.我的AdminController包含此方法

function preDispatch()
{
    $auth = Zend_Auth::getInstance();
    if (!$auth->hasIdentity()) {
        $this->_redirect('auth/login');
    }
}

用户被重定向到AuthController,但在成功登录后被重定向到我的网站的默认"索引"页面,而不是"管理员"页面.

function loginAction()
{
    if (strtolower($_SERVER['REQUEST_METHOD']) == 'post') {
        // collect the data from the user
        Zend_Loader::loadClass('Zend_Filter_StripTags');
        $filter = new Zend_Filter_StripTags();
        $username = $filter->filter($this->_request->getPost('username'));
        $password = $filter->filter($this->_request->getPost('password'));

        if (empty($username)) {
            $this->view->message = 'Please provide a username.';
        } else {
            // setup Zend_Auth adapter for a database table
            $dbAdapter = Zend_Db_Table::getDefaultAdapter();

            //Zend_Loader::loadClass('Zend_Auth_Adapter_DbTable');
            $authAdapter = new Zend_Auth_Adapter_DbTable($dbAdapter);
            $authAdapter->setTableName('login');
            $authAdapter->setIdentityColumn('email');
            $authAdapter->setCredentialColumn('password');

            // Set the input credential values to authenticate against
            $authAdapter->setIdentity($username);
            $authAdapter->setCredential($password);

            // do the authentication 
            $auth = Zend_Auth::getInstance();
            $result = $auth->authenticate($authAdapter);
            if ($result->isValid()) {
                // success : store database row to auth's storage system (not the password though!)
                $data = $authAdapter->getResultRowObject(null, 'password');
                $auth->getStorage()->write($data);
                // I THINK I NEED TO CHANGE THIS LINE
                $this->_redirect('/'); 
            } else {
                // failure: clear database row from session
                $this->view->message = 'Login failed.';
            }
        }
    }
    $this->render();   
}

Zend配置preDispatch()方法的正确方法是什么,以便我可以告诉AuthController重定向到最初请求的页面？

您应该记住preDispatch中的当前网址,然后在您的登录操作中重定向到该网址.例:

public function preDispatch()
{
    $requestUri = Zend_Controller_Front::getInstance()->getRequest()->getRequestUri();

    $session = new Zend_Session_Namespace('lastRequest');
    $session->lastRequestUri = requestUri;

    // ...
}

public function loginAction()
{
    // ...

    $session = new Zend_Session_Namespace('lastRequest');
    if (isset($session->lastRequestUri)) {
        $this->_redirect($session->lastRequestUri);
        return;
    }

    // ...
}

您可以为此编写自己的Zend_Controller_Action_Helper.您也可以检查HTTP_REFERRER,但对我来说,会话​​是存储此类数据的更可靠方式.
