如何在zf2中使用户名不区分大小写 [英] How to make username case insensitive in zf2
本文介绍了如何在zf2中使用户名不区分大小写的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在项目中使用zf2身份验证对用户进行身份验证.我在用户表中保存了Harib作为用户名，但是如果我使用用户名Harib则接受它，或者如果我使用harib则不接受，我想删除大小写用户名的敏感性，这样Harib或harib都可以访问该怎么解决?
I used zf2 authentication for authenticate user in my project.I saved Harib in my user table as user name but if i use my user name Harib then its accept or if i use harib then its not accept,i want to remove case sensitivity of user name so both Harib or harib access how i fix this?
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();
}
//create token
$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
if(is_object($token) && property_exists($token, 'id')){
$time = time() + (60 * 60 * 24 * 30); // 1 month
setcookie('token', $token->getProperty('id'), $time, '/');
}
}
if ($user_data['user_type'] == 'onlinemarketer') {
$this->redirect()->toRoute('admin_program_meta');
} elseif ($user_data['user_type'] == 'bucharestofficemanager') {
$this->redirect()->toRoute('admin_program_detail_request');
} else {
if ($this->params('redirect') && urldecode($this->params('redirect')) !== '/logout/') {
$server_url = $this->getRequest()->getUri()->getScheme() . '://' . $this->getRequest()->getUri()->getHost().urldecode($this->params('redirect') . $hashed_string);
return $this->redirect()->toUrl($server_url);
}
return $this->redirect()->toRoute('admin_index');
}
}
} else {
$identity = false;
$login_error = true;
}
}
}
return new ViewModel(array(
'loginForm' => $loginForm,
'form_elements' =>$form_elements,
'login_error' => $login_error,
));
}
这是我的登录表单代码:

}
我们如何删除用户名的区分大小写，以便同时接受Harib或harib?
how we remove case sensitivity of user name so both Harib or harib accepted?
推荐答案
由于您使用的是MongoDB，因此可以使用正则表达式从数据库中获取用户名.
Since you're using MongoDB, you could use a regex to get the user name from the database.
建议1:
在您的示例中，将是:
db.stuff.find( { foo: /^bar$/i } );
建议2:
您可以使用$ options => i进行不区分大小写的搜索.给出一些字符串匹配所需的示例.
You can Use $options => i for case insensitive search. Giving some possible examples required for string match.
不区分大小写的字符串
db.collection.find({name:{'$regex' : '^string$', '$options' : 'i'}})
包含字符串
db.collection.find({name:{'$regex' : 'string', '$options' : 'i'}})
以字符串开头
db.collection.find({name:{'$regex' : '^string', '$options' : 'i'}})
以字符串结尾
db.collection.find({name:{'$regex' : 'string$', '$options' : 'i'}})
不包含字符串
db.collection.find({name:{'$regex' : '^((?!string).)*$', '$options' : 'i'}})
