Ошибка интерпретации файла изображения формата jpeg not a jpeg file starts with 0xef 0xbf

I have to trying download file which are in our system.FOr this I used spring boot and angular js 1.
The file is downloaded but is not open with message Error interpreting JPEG image file (Not a JPEG file: starts with 0xef 0xbf).
My sample code is —

DownloadService.java


import com.codahale.metrics.annotation.Timed;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Component;

 public void downloadFile(@Context HttpServletResponse response) throws IOException {
  String filePath = ("/home/ashish/Desktop/CTA.jpg");
  File fileName = new File(filePath);
  String mimeType = URLConnection.guessContentTypeFromName(fileName.getName());
  if (mimeType == null) {
   System.out.println("mimetype is not detectable, will take default");
   mimeType = "application/octet-stream";
  }
  response.setContentType(mimeType);
  response.setHeader("Content-Disposition", String.format("inline; filename="" + fileName.getName() + """));
  response.setContentLength((int) fileName.length());
  InputStream inputStream = new BufferedInputStream(new FileInputStream(fileName));
  FileCopyUtils.copy(inputStream, response.getOutputStream());
  inputStream.close();

 }
}



download.js


app.controller('storeReportsCtrl', function($rootScope, $scope, Restangular, $state, $stateParams, $location, $modal, $log, $timeout,$http,$sce) {
$scope.download = function(fileName) {

$http.get('/api/1/download/downloadFile', {responseType:'arraybuffer'})
             .success(function (response) {
               var a = document.createElement("a");
                   document.body.appendChild(a);
                   a.style = "display: none";
                   var fileName = "ppt2.jpg";
                  // var mimeType = data.mimeType;
                    var blob = new Blob([response], {type: 'image/jpeg'}),
                     url = window.URL.createObjectURL(blob);
                       a.href = url;
                       a.download = fileName;
                       a.click();
                       window.URL.revokeObjectURL(url);
             }).catch(function(error) {
                  console.log(error);
                 });
           }
});

From this file is downloaded but it is corrupted means my original file size is 18,394 bytes and response.byteLength = 33496.

UPDATE

Same code is working fine for text file but for binary file it not works.

How can I download correct file..

How can I download correct file..

I did some sample uploads to OneDrive using graph api. I’m able to upload files(text files) successfully through OkHttp. But, when it comes to images i’m getting this message after opening image

Error interpreting JPEG image file (Not a JPEG file: starts with 0xef 0xbf)

after uploading image to onedrive. .svg format images are uploading successfully but .jpg, .png format images are corrupting when uploading to one drive.

The following is my way of approach

Converting the image to Byte array and then converting(writing) that Byte array to uploading file.

The code for converting image to byte array

byte[] contentBuilder = IOUtils.toByteArray(file.getObjectContent());

Code for uploading the byte array to onedrive as its original form.

String url = "https://graph.microsoft.com/v1.0/drive/root:/" + step.file_name + ":/content";

                        Request request = new Request.Builder().url(url)
                                .put(RequestBody.create(MediaType.parse("image/*"), step.file_data))
        //step.file_data contains the byte array.
                                .addHeader("Authorization", String.format("Bearer %s", step.getAccess_token()))
                                .build();
    Response response = okHttpClient.newCall(request).execute();

This approach is working for text files and .svg format images but not for other format images. I went through many references/websites but unable to find a way. What could be the reason!
Thank you 🙂 in advance

Я сделал несколько примеров загрузки в OneDrive с помощью графического API. Я могу успешно загружать файлы (текстовые файлы) через OkHttp. Но когда дело доходит до изображений, я получаю это сообщение после открытия изображения.

Error interpreting JPEG image file (Not a JPEG file: starts with 0xef 0xbf)

После загрузки изображения на onedrive. Образы формата .svg загружаются успешно, но образы формата .jpg, .png повреждаются при загрузке на один привод.

Вот мой подход

Преобразование изображения в массив байтов, а затем преобразование (запись) этого массива байтов в загружаемый файл.

Код для преобразования изображения в байтовый массив

byte[] contentBuilder = IOUtils.toByteArray(file.getObjectContent());

Код для загрузки байтового массива в onedrive в его исходной форме.

String url = "https://graph.microsoft.com/v1.0/drive/root:/" + step.file_name + ":/content";

                        Request request = new Request.Builder().url(url)
                                .put(RequestBody.create(MediaType.parse("image/*"), step.file_data))
        //step.file_data contains the byte array.
                                .addHeader("Authorization", String.format("Bearer %s", step.getAccess_token()))
                                .build();
    Response response = okHttpClient.newCall(request).execute();

Этот подход работает для текстовых файлов и изображений в формате .svg, но не для изображений в других форматах. Я просмотрел много ссылок / веб-сайтов, но не смог найти способ. Что может быть причиной!
Заранее спасибо
