Question

我正在尝试使用blobstore API，但是我有这个错误：

com.google.api.server.spi.SystemService invokeServiceMethod：调用后台方法时发生异常 com.google.apphosting.api.ApiProxy $ CallNotFoundException：找不到API包'file'或调用'Create（）'。在java.lang.Thread.getStackTrace（Thread.java:1589）在com.google.apphosting.api.ApiProxy.makeSyncCall（ApiProxy.java:116）在com.google.apphosting.api.ApiProxy.makeSyncCall（ApiProxy.java:65）在com.google.appengine.api.files.FileServiceImpl.makeSyncCall（FileServiceImpl.java:590）在com.google.appengine.api.files.FileServiceImpl.create（FileServiceImpl.java:512）在com.google.appengine.api.files.FileServiceImpl.createNewBlobFile（FileServiceImpl.java:111）在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）在java.lang.reflect.Method.invoke（Method.java:45）在com.google.api.server.spi.SystemService.invokeServiceMethod（SystemService.java:359）在com.google.api.server.spi.SystemServiceServlet.execute（SystemServiceServlet.java:113）在com.google.api.server.spi.SystemServiceServlet.doPost（SystemServiceServlet.java:71）在javax.servlet.http.HttpServlet.service（HttpServlet.java:637）在javax.servlet.http.HttpServlet.service（HttpServlet.java:717）在org.mortbay.jetty.servlet.ServletHolder.handle（ServletHolder.java:511）在org.mortbay.jetty.servlet.ServletHandler $ CachedChain.doFilter（ServletHandler.java:1166）在org.mortbay.jetty.servlet.ServletHandler $ CachedChain.doFilter（ServletHandler.java:1157）在org.mortbay.jetty.servlet.ServletHandler $ CachedChain.doFilter（ServletHandler.java:1157）在org.mortbay.jetty.servlet.ServletHandler $ CachedChain.doFilter（ServletHandler.java:1157）在org.mortbay.jetty.servlet.ServletHandler $ CachedChain.doFilter（ServletHandler.java:1157）在org.mortbay.jetty.servlet.ServletHandler.handle（ServletHandler.java:388）在org.mortbay.jetty.security.SecurityHandler.handle（SecurityHandler.java:216）在org.mortbay.jetty.servlet.SessionHandler.handle（SessionHandler.java:182）在org.mortbay.jetty.handler.ContextHandler.handle（ContextHandler.java:765）在org.mortbay.jetty.webapp.WebAppContext.handle（WebAppContext.java:418）在org.mortbay.jetty.handler.HandlerWrapper.handle（HandlerWrapper.java:152）在org.mortbay.jetty.Server.handle（Server.java:326）在org.mortbay.jetty.HttpConnection.handleRequest（HttpConnection.java:542） at org.mortbay.jetty.HttpConnection $ RequestHandler.headerComplete（HttpConnection.java:923）在org.mortbay.jetty.HttpConnection.handle（HttpConnection.java:404）在com.google.tracing.TraceContext $ TraceContextRunnable.runInContext（TraceContext.java:437）在com.google.tracing.TraceContext $ TraceContextRunnable $ 1.run（TraceContext.java:444）在com.google.tracing.CurrentContext.runInContext（CurrentContext.java:230）在com.google.tracing.TraceContext $ AbstractTraceContextCallback.runInInheritedContextNoUnref（TraceContext.java:308）在com.google.tracing.TraceContext $ AbstractTraceContextCallback.runInInheritedContext（TraceContext.java:300）在com.google.tracing.TraceContext $ TraceContextRunnable.run（TraceContext.java:441）在java.lang.Thread.run（Thread.java:745）

我使用此代码：

@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;
        }

你能帮助我吗？

看来文件API在2013年已被弃用，并最终在今年被禁用。请参阅：https://cloud.google.com/appengine/docs/deprecations/files_api

未找到API包“文件”或调用“创建（）”
