File Can'；无法在zf2中进行上传。文件始终无效？

我正在尝试创建一个控制器，为我上传一个文件，但我总是得到相同的结果。该文件无效，因此他无法上载

我的控制器中的功能是：

$upload = new \Zend\File\Transfer\Transfer();
    $upload->setDestination('./data/images/uploads/');

    $rtn = array('success' => null);

    if ($this->getRequest()->isPost()) {
        $files = $upload->getFileInfo();
        foreach ($files as $file => $info) {
            if (!$upload->isUploaded($file)) {
                print "<h3>Not Uploaded</h3>";
                \Zend\Debug\Debug::dump($file);   
                continue;
            }
            if (!$upload->isValid($file)) {
                print "<h4>Not Valid</h4>";
                \Zend\Debug\Debug::dump($file);
                continue;
            }
        }

        $rtn['success'] = $upload->receive();
    }

    return new \Zend\View\Model\JsonModel($rtn);

正如您在中所看到的，使用

Zend\file\Transfer

上传文件已被弃用，取而代之的是使用标准ZF2

Zend\Form

和

Zend\InputFilter

功能

话虽如此，您应该使用

Zend\Filter\File\RenameUpload

移动上传的文件。您只需将

Zend\Filter\File\RenameUpload

过滤器附加到

InputFilter

规范，如下所示：

if ($this->request->isPost()) {
    $post = array_merge_recursive(
        $this->request->getPost()->toArray(),
        $this->request->getFiles()->toArray()
    );

    $form->setData($post);

    if ($form->isValid()) {
        // File uploaded and moved to data/uploads folder
    }
}

在控制器操作中：
