Question

我在运行登录验证码时遇到错误。我正在使用zend框架＆amp;作为IDE的zend工作室

在使用身份验证之前未提供身份的值 Zend_Auth_Adapter_DbTable。

以下是我写的代码：

public function authAction(){
        $request    = $this->getRequest();
        $registry   = Zend_Registry::getInstance();
        $auth       = Zend_Auth::getInstance();

        $DB = $registry['zenddb']; //zenddb is database name

        $authAdapter = new Zend_Auth_Adapter_DbTable($DB);
        $authAdapter->setTableName('user');



        $authAdapter->setIdentityColumn('user_name');
        $authAdapter->setCredentialColumn('password');

        // Set the input credential values
        $uname = $request->getParam('user_name');
        $paswd = $request->getParam('password');
        $authAdapter->setIdentity($uname);
        $authAdapter->setCredential(md5($paswd));

        // Perform the authentication query, saving the result
        $result = $auth->authenticate($authAdapter);

        if($result->isValid()){
            $data = $authAdapter->getResultRowObject(null,'password');
            $auth->getStorage()->write($data);
            $this->_redirect('userpage');
        }else{
            $this->_redirect('login');
        }
    }

Answer 1

当您在表单中将凭据字段留空时，通常会发生此错误，

所以zend纠正是一个catch块，它会抛出你提到的错误。 Official Ticket

您可以通过在与空字段相关的字段上进行验证来解决此问题。 //例如'required' => true

希望它有所帮助。

 public function loginAction()
    {
        $this->_helper->layout->setLayout('loginlayout');

                $request = $this->getRequest();
                $form    = new Application_Form_loginForm();
                $login="";

                if ($this->getRequest()->isPost()) {
                    if ($form->isValid($request->getPost())) {
                        $request    = $this->getRequest();
                        // Set the input credential values
                    $registry   = Zend_Registry::getInstance();
                $auth       = Zend_Auth::getInstance();


                $params = array('host'      =>'localhost',
                        'username'  =>'root',
                        'password'  =>'',
                        'dbname'    =>'zendDb'
                );


                $DB = new Zend_Db_Adapter_Pdo_Mysql($params);


                $authAdapter = new Zend_Auth_Adapter_DbTable($DB);

                $authAdapter->setTableName('user');
                $authAdapter->setIdentityColumn('user_name');
                $authAdapter->setCredentialColumn('password');
                $request    = $this->getRequest();
                // Set the input credential values
                $uname = $request->getParam('user_name');

                $paswd = $request->getParam('password');

                $authAdapter->setIdentity($uname);
                $authAdapter->setCredential(md5($paswd));

                $auth       = Zend_Auth::getInstance();
                // Perform the authentication query, saving the result
                $result = $auth->authenticate($authAdapter);

                if($result->isValid()){
                    $data = $authAdapter->getResultRowObject(null,'password');

                    $auth->getStorage()->write($data);
                    $login="";
                    $this->_redirect('database/user');
                }else{

                   $login="Invalid User Name or Password";

                    //$this->_redirect('database/login');
                }


                //return $this->_helper->redirector('auth');
            }
            }
            else {
                $login="";
            }

            $this->view->assign('title','Login');
            $this->view->assign('description',$login);
            $this->view->form = $form;

    }

Answer 3

if ($this->getRequest()->isPost()) {
    if ($form->isValid($request->getPost())){
        //Simply Wrap your Code between this two conditions.
    }
}

正如你在这里看到的那样：

首先，你必须检查请求是否是POST。

其次，您必须检查它是否对您的表单有效。
