php - 如何在 zf2 中使用户名不区分大小写

Question

我在我的项目中使用 zf2 身份验证来验证用户。我将 Harib 作为用户名保存在我的用户表中，但是如果我使用我的用户名 Harib 那么它接受或者如果我使用 harib 那么它不接受，我想删除大小写用户名的敏感性，因此 Harib 或 harib 都可以访问我如何解决这个问题？

这是我的代码:

public function loginAction()
{
    $this->layout('layout/login-layout.phtml');
    $login_error = false;
    $loginForm = new LoginForm();
    $form_elements = json_encode($loginForm->form_elements);
    if ($this->request->isPost()) {
        $post = $this->request->getPost();
        $loginForm->setData($post);
        if ($loginForm->isValid()) {
            $hashed_string = '';
            if(
                array_key_exists('hashed_input' , $post) &&
                $post['hashed_input'] != '' &&
                strpos(urldecode($this->params('redirect')) , 'programdetailrequest') !== false
            ) {
                $hashed_string = $post['hashed_input'];
            }
            $data = $loginForm->getData();
            $authService = $this->getServiceLocator()->get('doctrine.authenticationservice.odm_default');
            $adapter = $authService->getAdapter();
            $adapter->setIdentityValue($data['username']);
            $adapter->setCredentialValue(md5($data['password']));
            $authResult = $authService->authenticate();
            if($authResult->isValid()){
                $identity = $authResult->getIdentity();
                if( is_object($identity) && method_exists($identity, 'getData') ){
                    $user_data = $identity->getData();
                    $authService->getStorage()->write($identity);
                    // for remeber checkbox
                    if ($post['rememberme']) {
                        $token = new UserToken();
                        $dm = $this->getServiceLocator()->get('doctrine.documentmanager.odm_default');
                        //if same user already running from other browser then remove previous token.
                        $check_token = $dm->getRepository('Admin\Document\UserToken')->findOneBy(array( "user_id.id" => $user_data['id'] ));
                        if (is_object($check_token) && !is_null($check_token)) {
                            $remove_token = $dm->createQueryBuilder('Admin\Document\UserToken')
                                ->remove()
                                ->field('id')->equals($check_token->id)
                                ->getQuery()->execute();
                        }

                        $user = $dm->getRepository('Admin\Document\User')->findOneBy(array( "id" => $user_data['id'] ));
                        $token->setProperty('user_id', $user);
                        $token->setProperty('dataentered', new \MongoDate());
                        $dm->persist($token);
                        $dm->flush($token);
                        //create cookie

                            $time = time() + (60 * 60 * 24 * 30); // 1 month
                            setcookie('token', $token->getProperty('id'), $time, '/');
                        }
                    }
                    if ($user_data['user_type'] == 'onlinemarketer') {

我们如何删除用户名的大小写敏感度以便同时接受 Harib 或 harib？

Answer 1

在元素 user_id 上的 loginform 中添加过滤器 StringToLower。

为此，定义您的 loginform 的类必须实现 InputFilterProviderInterface 并且您必须添加 getInputFilterSpecification 方法，如下所示:

public function getInputFilterSpecification()
{
    return [
        'username' => [
            'name' => 'username',
            'required' => true,
            'filters' => [
                'name' => 'StringToLower',
                'name'=>'StripTags',
                'name'=>'StringTrim' 
            ],
            validators => [
                [
                    'name'=>'Regex',
                    'options'=> [
                        'pattern' => '/^[a-z0-9_.-]{1,50}+$/', 
                        'pattern_js' => '^[a-zA-Z0-9_\.\-]{1,50}$' 
                    ]
                ]
            ] 
        ],
        'password' => [
            'name' => 'password',
            'required' => true,
            'filters' => [
                array('name'=>'StripTags'),
                array('name'=>'StringTrim')
            ],
            'validators' => [
                [
                    'name'=>'Regex',
                    'options'=> [
                    'pattern' => '/^[a-z0-9_.-]{6,25}+$/', 
                    'pattern_js' => '^[a-zA-Z0-9_\.\-]{6,25}$' 
                    ]
                ]
            ]
        ]
    ];
}

因此您可以放心，帖子中返回的值是小写的。
