Php 带有jQuery文件上载UI的OneUploader

我正在尝试在symfony2网站上使用OneUploaderBundle设置jQuery文件上载UI

在经历了很多痛苦之后，上传过程按我所希望的那样工作，但我无法让Json响应在上传过程中起作用

我使用了OneUploaderBundle的postPloadeEvent，并绑定了很多解决方案来向jQuery文件上传UI发送corecte jSon响应，但在上传文件时仍然会收到一条错误消息

在doc中，请求发送如下回复：

{"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是正常的。 我试着用同样的回答

return new JsonResponse($jsonResponse); 

使用普通响应对象和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（）；物体的形状。 但什么都不管用

有人能帮我吗？ 先谢谢你
