如何在zend中獲取認證適配器？

Question

我是this教程，在我的應用程序中實現登錄系統。這是給我下面的過程動作錯誤：

Message: Method "getAuthAdapter" does not exist and was not trapped in __call() 

上以下行：

$adapter = $this->getAuthAdapter($form->getValues()); 

所以現在我要實現getAuthAdapter（）函數，但如何在這個功能代碼。

感謝

Answer 1

創建您自己的身份驗證功能：

protected function _getAuthAdapter($userLogin, $userPass){ 
    $authAdapter = new Zend_Auth_Adapter_DbTable(
     Zend_Db_Table::getDefaultAdapter(), 
     'user', //db table name 
     'login', // identity column 
     'password' // credential column 
    ); 
    $authAdapter->setIdentity($userLogin)->setCredential($userPass); 
    return $authAdapter; 
} 

數據庫驗證文檔，你可以找到here

對於其他適配器看看here

你可以，如果你想通過數據庫來驗證您可以使用此代碼使用此example

所以這是我完整的解決方案：

<?php 

class AuthenticationController extends Zend_Controller_Action { 

    public function init() { 
     /* Initialize action controller here */ 
    } 

    public function indexAction() { 
     // action body 
    } 

    /** 
    * Show login form 
    */ 
    public function loginAction() { 

     $this->view->heading = 'Login'; 
     $this->view->form = new Form_Login(); 
     $this->view->form->setAction('process'); 
    } 

    /** 
    * preDispatch: If user is already logged in then 
    * redirect to index, if not then redirect to login 
    */ 
    public function preDispatch() { 

     if (Zend_Auth::getInstance()->hasIdentity()) { 
      // If the user is logged in, we don't want to show the login form; 
      // however, the logout action should still be available 
      if ('logout' != $this->getRequest()->getActionName()) { 
       $this->_helper->redirector('index', 'index'); 
      } 
     } else { 
      // If they aren't, they can't logout, so that action should 
      // redirect to the login form 
      if ('logout' == $this->getRequest()->getActionName()) { 
       $this->_helper->redirector('login'); 
      } 
     } 
    } 

    /** 
    * Provide authentication adapter 
    * 
    * @param unknown_type $values 
    */ 
    public function getAuthAdapter($values) { 

     $authAdapter = new Zend_Auth_Adapter_DbTable(Zend_Db_Table::getDefaultAdapter(), 
                 'Authentication', 
                 'username', 
                 'password', 
                 'MD5(CONCAT(salt,?))' 
                ); 

     $authAdapter->setIdentity($values['username']); 
     $authAdapter->setCredential($values['password']);           

     return $authAdapter; 
    } 

    /** 
    * Process login request. If user is authenticated 
    * then redirect to index otherwise show login form again 
    */ 
    public function processAction() { 

     $request = $this->getRequest(); 

     // Check if we have a POST request 
     if (!$request->isPost()) { 
      return $this->_helper->redirector('login'); 
     } 

     // Get our form and validate it 
     $form = new Form_Login(); 
     if (!$form->isValid($request->getPost())) { 
      // Invalid entries 
      $this->view->form = $form; 
      return $this->render('login'); // re-render the login form 
     } 

     // Get login form values 
     $values = $form->getValues(); 

     // Get our authentication adapter and check credentials 
     $adapter = $this->getAuthAdapter($values); 
     $auth = Zend_Auth::getInstance(); 
     $result = $auth->authenticate($adapter); 

     if (!$result->isValid()) { 
      // Invalid credentials 
      $form->setDescription('Invalid credentials provided'); 
      $this->view->form = $form; 
      $this->_helper->redirector('login'); // re-render the login form 
     } 

     // Create session 
     $session = new Zend_Session_Namespace('user'); 
     $session->userEmail = $values['username']; 
     $session->userId = '1'; 

     // We're authenticated! Redirect to the home page 
     $this->_helper->redirector('index', 'index'); 
    } 

    /** 
    * logout request 
    */ 
    public function logoutAction() { 

     // Destroy session 
     $session = new Zend_Session_Namespace('user'); 
     $session->userEmail = null; 
     $session->userId = null; 

     Zend_Auth::getInstance()->clearIdentity(); 
     $this->_helper->redirector('login'); // back to login page 
    } 


} // end class
