我没有自己实现 Doctrine 的身份验证服务,而是决定通过我的身份验证表单的 isValid() 方法中的表单验证来实现它。
例子:
<?php
namespace My\Form\Namespace;
use Zend\Form\Form;
use Zend\ServiceManager\ServiceLocatorInterface;
use Zend\InputFilter\InputFilterProviderInterface;
class Auth extends Form implement InputFilterProviderInterface
{
protected $_em;
public function __construct(ServiceLocatorInterface $sm)
{
parent::__construct('auth');
// inject Doctrine's Entity Manager
$this->_em = $sm->get('Doctrine\ORM\EntityManager');
// login field
$this->add(...);
// password field
$this->add(...);
// group_name field
$this->add(...);
}
public function getInputFilterSpecification()
{
//Input filter specification here
...
}
public function isValid()
{
/*
* input filter validations
*/
if (!parent::isValid())
return false;
/*
* group exists validation
*/
$group = $this->_em
->getRepository('<Group\Entity\Namespace>')
->findOneBy(array(
'name' => $this->get('group_name')->getValue(),
));
if (!$group){
$this->get('group_name')
->setMessages(array(
'Group not found',
));
return false;
}
/*
* user exists validation
*/
$user = $this->_em
->getRepository('<User\Entity\Namespace>')
->findOneBy(array(
'group_id' => $group->getId(),
'name' => $this->get('login')->getValue(),
));
if (!$user){
/*
* It's not good idea to tell that user not found,
* so let it be password error
*/
$this->get('password')
->setMessages(array(
'Login or password wrong',
));
return false;
}
/*
* password validation
*/
$password = $this->get('password')->getValue();
// assume that password hash just md5 of password string
if (md5($password) !== $user->getPassword()){
$this->get('password')
->setMessages(array(
'Login or password wrong',
));
return false;
}
return true;
}
}
$form->isValid()
在控制器内部,调用以确保用户输入了正确的身份验证数据就足够了。
