在Laravel中Dropzone.js请求为空

Question

我正在使用Dropzone.js在Laravel中上传多个图像。尽管图像上传没有任何错误，但请求为空。有什么解决办法吗？

HTML代码

<form class="form-horizontal" id="form" method="post" enctype="multipart/form-data">
   <div class="form-group">
     <label class="col-sm-2 control-label">ISSUE DATE / VOLUME NO</label>
     <div class="col-sm-10"><input type="text" class="form-control" name="valume_no" value={{ old('valume_no') }}></div>
   </div>
   <div class="dropzone" id="my-dropzone">
      <div class="dz-message">
         <div class="col-xs-8">
            <div class="message">
               <p>Drop files here or Click to Upload</p>
            </div>
         </div>                    
      </div>
      <div class="fallback">
        <input name="featured_file" type="file[]" multiple />
      </div>
   </div>
   <div class="form-group">
     <div class="col-sm-8 col-sm-offset-2"> 
    <button class="btn btn-primary" type="submit">Done</button>
     </div>
   </div>
</form>

防区配置

Dropzone.autoDiscover = false;
    $(document).ready(function () {
        $("#my-dropzone").dropzone({ 
            url: '{{ url("/news/uploadimgsaddmode") }}',
            headers: {
                    'x-csrf-token': "{{ csrf_token() }}",
                    },
            method: 'post',
            paramName: "file",
            maxFiles: 100,
            maxFileSize: 100,
            acceptedFiles: ".jpeg,.jpg,.png",
            uploadMultiple: true,
            parallelUploads: 100,
            previewTemplate: document.querySelector('#preview').innerHTML,
            addRemoveLinks: true,
            dictRemoveFile: 'Remove file',
            dictFileTooBig: 'Image is larger than 16MB',
            timeout: 10000,                        
            success: function (file, response) {
                console.log(response);
            }
        });        
    });

Laravel控制器

public function uploadimgsaddmode(Request $request){      
    return Response::json(['message' => $request], 200);                
}

响应

{"message":[{}]}
