验证Zend Framework 2中的文件

检查下面的代码,我从上传中获取文件,我想验证它。我检查文件扩展名,大小和MIME。如果我逐一检查它们的结果是否正确,但是当我使用$ adapter-> setValidators()时,结果是误报。

ZF2验证器是否以奇怪的方式行事,或者我不明白我应该如何使用它?

CODE

<?php    
    $data = array_merge_recursive(
        $this->getRequest()->getPost()->toArray(),          
        $this->getRequest()->getFiles()->toArray()
    );

    /* set mime on server side */
    $finfo = new \finfo(FILEINFO_MIME);             
    $mimeinfo = explode(';', $finfo->file($data['upload_image']['tmp_name']));
    $data['upload_image']['type'] = $mimeinfo[0];

    $adapter = new \Zend\File\Transfer\Adapter\Http(); 

    $validatorSize = new \Zend\Validator\File\Size(10);
    $validatorExt = new \Zend\Validator\File\Extension('gif,jpg,jpeg,png');
    $validatorMime = new \Zend\Validator\File\MimeType('image/gif,image/jpg,image/jpeg,image/png');

    $results = array();
    $results['size'] = $validatorSize->isValid($data['upload_image']);
    $results['ext'] = $validatorExt->isValid($data['upload_image']);
    $results['mime'] = $validatorMime->isValid($data['upload_image']);

    $adapter->setValidators(array(
        $validatorSize,
        $validatorExt,
        $validatorMime,
    ), $data['upload_image']);

    $results['adapter'] = $adapter->isValid();

    \Zend\Debug\Debug::dump($results);
?>

结果

array(4) {
  ["size"] => bool(false)
  ["ext"] => bool(true)
  ["mime"] => bool(false)
  ["adapter"] => bool(true)
}

我希望我正确理解问题的含义:)你可以使用addValidator()方法,第二个参数是$ breakChainOnFailure。这种行为对于验证者链是正确的。如果没有明确中断,将执行每个验证器。
