我正试图在symfony2网站上使用oneupuploaderBundle设置jQuery File Upload UI。
在流了很多眼泪之后，上传过程按照我的意愿进行，但我无法使Json的响应在上传后正常工作。
我使用oneupuploaderBundle的PostUploadEvent，并绑定了很多解决方案来向jQuery File Upload UI发送一个corecte jSon响应，但当文件上传时，我仍然有一条错误消息。
在文档中，请求发送这样的回复：
{"files": [
{
"name": "picture1.jpg",
"size": 902604,
"url": "http://example.org/files/picture1.jpg",
"thumbnail_url": "http://example.org/files/thumbnail/picture1.jpg",
"delete_url": "http://example.org/files/picture1.jpg",
"delete_type": "DELETE"
}
]}
这是我的：
{"files": [
{
"url": "/ishowpro-cms/web/app_dev.php/library/file/image/originals/51dbd9a13a065-screen-shot-mini.png",
"thumbnail_url": "/ishowpro-cms/web/app_dev.php/library/file/image/thumbnails/51dbd9a13a065-screen-shot-mini.png",
"name": "screen-shot-mini.png",
"type": "image/png",
"size": 1192,
"delete_url": "http://nourltodelete.com",
delete_type: "DELETE"
}
] }
URL正常。我试图用返回响应
return new JsonResponse($jsonResponse);
使用Normal响应对象和json头，我尝试创建一个实体并序列化它：
$responseObjectFile = new JqUploaderFile();
$responseObjectFile->setName();
$responseObjectFile->setSize();
$responseObjectFile->setUrl();
$responseObjectFile->setThumbnail_url();
$responseObjectFile->setDelete_url($this->router->generate('show_image_link', array('slug'=>$file->getSlug(), 'extension'=>$file->getExtension(), 'size'=>'originals'), true));
$responseObjectFile->setDelete_type("DELETE");
//create serializer to encode Entity
$encoders = array(new XmlEncoder(), new JsonEncoder());
$normalizers = array(new GetSetMethodNormalizer());
$serializer = new Serializer($normalizers, $encoders);
$jsonContent = $serializer->serialize($responseObjectFile, 'json');
//add entity in array and unserilize it....
$responseCode = array('files'=>array($jsonContent) );
还可以使用$event->getRequest（）；对象的。但什么都不管用。
他们有人能帮我吗？提前谢谢。

感谢devsheeep，这里是解决方案。当你知道的时候真的很简单：
$response = $event->getResponse();
$files = array();
$files[0] = array(
'name' => $file->getFileName(),
'size' => $file->getSize(),
'url' => "Your URL",
'thumbnail_url' => "Your thumb URL",
'delete_url' =>"Your delete URL",
'delete_type' => 'DELETE'
);
$response['files'] = $files;
并且我们处于事件上下文中，返回值没有任何影响。相反，我们正在使用参考资料。因此，只需省略return语句。
5创造它，我喜欢。再次感谢desheep和1up.io团队，他们是Symfony框架的优秀专业人士。
