很多时候,在Zend Framework 2视图中,我将调用$this->escapeHtml()
来确保我的数据是安全的。有没有办法将此行为从黑名单切换到白名单?
PS:阅读Padraic Brady的一篇文章,其中提到automatic escaping is a bad idea。额外的想法?

您可以编写自己的ViewModel
类,在将变量分配给它时会转义数据。

感谢Robs评论,我扩展了ZF2 ViewModel,如下所示:
namespace Application\View\Model;
use Zend\View\Model\ViewModel;
use Zend\View\Helper\EscapeHtml;
class EscapeViewModel extends ViewModel
{
/**
* @var Zend\View\Helper\EscapeHtml
*/
protected $escaper = null;
/**
* Proxy to set auto-escape option
*
* @param bool $autoEscape
* @return ViewModel
*/
public function autoEscape($autoEscape = true)
{
$this->options['auto_escape'] = (bool) $autoEscape;
return $this;
}
/**
* Property overloading: get variable value;
* auto-escape if auto-escape option is set
*
* @param string $name
* @return mixed
*/
public function __get($name)
{
if (!$this->__isset($name)) {
return;
}
$variables = $this->getVariables();
if($this->getOption('auto_escape'))
return $this->getEscaper()->escape($variables[$name]);
return $variables[$name];
}
/**
* Get instance of Escaper
*
* @return Zend\View\Helper\EscapeHtml
*/
public function getEscaper()
{
if (null === $this->escaper) {
$this->escaper = new EscapeHtml;
}
return $this->escaper;
}
}
在Controller中,它可以像这样使用:
public function fooAction()
{
return new EscapeViewModel(array(
'foo' => '<i>bar</i>'
));
//Turn off auto-escaping:
return new EscapeViewModel(array(
'foo' => '<i>bar</i>'
),['auto_escape' => false]);
}
