oneupuploader with jQuery-File-Upload UI

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。
