Güncelleme kullanılarak sunucuda dosya yükleme

Question

Projemde, android cihazdan sunucu siteye alınmış bir görüntüyü diske depolanması gereken yere göndermem gerekiyor. Cihaz sitesinde yöntemini çağırdığınızda yazık ki, bu hatayı karşılamak:

@Multipart 
@POST("/monument/photo/upload") 
void addMonumentPhoto(@Part("MonumentID") int monumentId, 
         @Part("name") String name, 
         @Part("subscript") String subscript, 
         @Part("photo") TypedFile photo, 
         Callback<Photo> callback); 

yöntemin ilanıdır

... ve ben onu aramak nasıl

photo = new File(selectedImageUri.getPath()); 
typedFile = new TypedFile("application/octet-stream", photo); 
MonumentsUtil.getApi().addMonumentPhoto(monument.getIdZabytek(), 
     "podpis", 
     "Main photo", 
     typedFile, 
     new Callback<Photo>() { 
    @Override 
    public void success(Photo aPhoto, Response response) { 
    } 

    @Override 
    public void failure(RetrofitError retrofitError) { 
     Log.e(TAG, retrofitError.getMessage()); 
    } 
}); 

@RequestMapping(value="/monument/photo/upload", method=RequestMethod.POST) 
public @ResponseBody Photo requestMonumentPhotoAdd(
     @RequestParam("MonumentID") int monumentId, 
     @RequestParam("name") String name , 
     @RequestParam("subscript") String subscript, 
     @RequestParam("photo") org.springframework.web.multipart.MultipartFile file) { 

    Photo photo = new Photo(); 
    photo.setIdZabytek(monumentId); 
    photo.setUri(URL+ "/images/" + name); 
    photo.setPodpis(subscript); 
    photo = monumentsRepo.addPhoto(photo); 
    String filePath = "D:\\Projekty\\Images\\" + monumentId + ":" + photo.getIdZjecia(); 

    if (!file.isEmpty()) { 
     try { 
      byte[] bytes = file.getBytes(); 
      BufferedOutputStream stream = new BufferedOutputStream(
       new FileOutputStream(new File(filePath))); 
      stream.write(bytes); 
      stream.close(); 
      photo.setUri(filePath); 
      monumentsRepo.updatePhoto(photo); 
      return photo; 
     } catch (Exception e) { 
      return null; 
     } 
    } else { 
     return null; 
    } 
} 

: sunucunun sitesinde böyle yöntemler var

Program hata bloğuna gider ve nedenini bilmiyorum. Hataya işaret eden ve neyin yanlış olduğunu açıklayan var mı?

DÜZENLEME

sonraki ben düzeltemez hata var benim kodunda düzeltilmesinden sonra

:

ve HTTP Yanıtı

Bence sunucunun yöntem yanlış yazılmış olabilir ama emin değilim. Herkes yardım edebilir mi?

Answer 1

Uri#getPathUri yol bileşenini değil dosya sistemi üzerinde yol döndürür. Gerçek görüntü için içerik sağlayıcıyı sorgulamanız gerekir. Buna benzer bir şey: https://stackoverflow.com/a/20186918/132047
