我正在尝试在 symfony2 网站上使用 oneuploaderBundle 设置 jQuery-File-Upload UI。
经过大量的泪水，上传过程按我的意愿工作，但我无法让 Json 响应工作 avec 上传。
我使用 oneuploaderBundle 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，但是当文件上传时我仍然有错误消息。
在文档中，要求发送这样的回复：
{"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"
}
] }
网址没问题。我试图用
return new JsonResponse($jsonResponse);
使用 Normal 响应对象和 json 标头，我尝试创建一个实体并将其序列化：
$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) );
并且还要使用 $event->getRequest(); 的对象。但没有任何效果。
请问他们的人可以帮助我吗？先感谢您。
这是完整的文件
