Question

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

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);

结果是：

 <h4>Not Valid</h4><pre>string(8) &quot;files_0_&quot;
 </pre>{"success":false}

当我查看$ files（print_r（））时，我得到：

Array
(
[files_0_] => Array
    (
        [name] => logo_welcome.gif
        [type] => image/gif
        [tmp_name] => /private/var/tmp/phpiufvIc
        [error] => 0
        [size] => 62935
        [options] => Array
            (
                [ignoreNoFile] => 
                [useByteString] => 1
                [magicFile] => 
                [detectInfos] => 1
            )

        [validated] => 
        [received] => 
        [filtered] => 
        [validators] => Array
            (
                [0] => Zend\Validator\File\Upload
            )

        [destination] => ./data/images/uploads
    )

)

正如您在ZF2 docs中所看到的，不推荐使用Zend\File\Transfer上传文件，而是赞成使用标准的ZF2 Zend\Form和Zend\InputFilter功能。

话虽如此，您应该使用Zend\Filter\File\RenameUpload来移动上传的文件。您只需将Zend\Filter\File\RenameUpload过滤器附加到InputFilter规范中，就像那样：

$this->add([
    'name' => 'file',
    'type' => 'Zend\InputFilter\FileInput',
    'filters' => [
        [
            'name' => 'FileRenameUpload',
            'options' => [
                'target'               => realpath('./data/uploads/'),
                'randomize'            => true,
                'use_upload_extension' => true,
            ],
        ],
    ],
]);

在你的控制器动作中：

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
    }
}

查看official documentation中的完整示例。

无法在zf2工作中上传。文件始终无效？
