的API包「文件」或稱之爲「創建（）」未找到

Question

我試圖使用Blob存儲區API，但我有此錯誤：

com.google.api.server.spi.SystemService invokeServiceMethod: exception occurred while calling backed method com.google.apphosting.api.ApiProxy$CallNotFoundException: The API package 'file' or call 'Create()' was not found. at java.lang.Thread.getStackTrace(Thread.java:1589) at com.google.apphosting.api.ApiProxy.makeSyncCall(ApiProxy.java:116) at com.google.apphosting.api.ApiProxy.makeSyncCall(ApiProxy.java:65) at com.google.appengine.api.files.FileServiceImpl.makeSyncCall(FileServiceImpl.java:590) at com.google.appengine.api.files.FileServiceImpl.create(FileServiceImpl.java:512) at com.google.appengine.api.files.FileServiceImpl.createNewBlobFile(FileServiceImpl.java:111) at com.listecourses.model.ListeModelEndpoint.insertListeModel(ListeModelEndpoint.java:182) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:45) at com.google.api.server.spi.SystemService.invokeServiceMethod(SystemService.java:359) at com.google.api.server.spi.SystemServiceServlet.execute(SystemServiceServlet.java:113) at com.google.api.server.spi.SystemServiceServlet.doPost(SystemServiceServlet.java:71) at javax.servlet.http.HttpServlet.service(HttpServlet.java:637) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:511) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1166) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1157) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1157) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1157) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1157) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:388) at org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java:216) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:182) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:765) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:418) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.Server.handle(Server.java:326) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:542) at org.mortbay.jetty.HttpConnection$RequestHandler.headerComplete(HttpConnection.java:923) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:404) at com.google.tracing.TraceContext$TraceContextRunnable.runInContext(TraceContext.java:437) at com.google.tracing.TraceContext$TraceContextRunnable$1.run(TraceContext.java:444) at com.google.tracing.CurrentContext.runInContext(CurrentContext.java:230) at com.google.tracing.TraceContext$AbstractTraceContextCallback.runInInheritedContextNoUnref(TraceContext.java:308) at com.google.tracing.TraceContext$AbstractTraceContextCallback.runInInheritedContext(TraceContext.java:300) at com.google.tracing.TraceContext$TraceContextRunnable.run(TraceContext.java:441) at java.lang.Thread.run(Thread.java:745)

我使用此代碼：

@ApiMethod(name = "insertListeModel", httpMethod = "POST") 
public ListeModel insertListeModel(ListeModel listemodel) { 
    EntityManager mgr = getEntityManager(); 
    try { 
     if (containsListeModel(listemodel)) { 
      throw new EntityExistsException("Object already exists"); 
     } 




     FileService fileService = FileServiceFactory.getFileService(); 
     if(listemodel.getImage()!=null && !listemodel.getImage().equals("")) 
     { 
      byte[] data = listemodel.getImage(); 




      String mimeType = "image/png"; 

      // save data to Google App Engine Blobstore 

      listemodel.setImage(null); 
      mgr.persist(listemodel); 
      AppEngineFile file; 
       file = fileService.createNewBlobFile(mimeType,"LM_"+listemodel.getId()); 
       FileWriteChannel writeChannel = fileService.openWriteChannel(file, true); 
       writeChannel.write(java.nio.ByteBuffer.wrap(data)); 
       writeChannel.closeFinally(); 

       // your blobKey to your data in Google App Engine BlobStore 
       BlobKey blobKey = fileService.getBlobKey(file); 

       // THANKS TO BLOBKEY YOU CAN GET FOR EXAMPLE SERVING URL FOR IMAGES 

       // UploadOptions uploadOptions = UploadOptions.Builder 
       //   .withGoogleStorageBucketName("photobucket11"); 

       // Get the image serving URL (in https:// format) 
       String imageUrl = ImagesServiceFactory.getImagesService().getServingUrl(ServingUrlOptions.Builder.withBlobKey(blobKey).secureUrl(true)); 

       //  ImagesService imagesService = ImagesServiceFactory 
       //    .getImagesService(); 
       //  ServingUrlOptions servingOptions = ServingUrlOptions.Builder 
       //    .withBlobKey(blobKey); 

       //  String imageUrl = imagesService.getServingUrl(servingOptions); 

       if(listemodel.getIdBlobkey()!=null) 
       { 
        BlobKey blobKeytmp= new BlobKey(listemodel.getIdBlobkey()); 
        final AppEngineFile f = fileService.getBlobFile(blobKeytmp); 

        if(f.isReadable()) 
        { 

         if(f.hasFinalizedName()) 
         { 
          fileService.delete(f); // Problematic line 
         } 
        } 

       } 

       listemodel.setAvatar(imageUrl); 
       listemodel.setIdBlobkey(blobKey.getKeyString()); 
     } 

       mgr.persist(listemodel); 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 


      } finally { 
       mgr.close(); 
      } 
      return listemodel; 
     } 

你能幫我嗎？

看來，文件API在2013年已被棄用，並最終在今年停用。參見：https://cloud.google.com/appengine/docs/deprecations/files_api
