从GoogleCloudStorage创建BlobstoreKey

Question

我正在使用GAE为一个项目编写此代码。我没有使用Blobstore，但我需要使用servingUrl方法。

    GcsFilename gcsFilename = new GcsFilename(myBucket, myFileName);
        BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService();
BlobKey blobKey = blobstoreService.createGsBlobKey(
    "/gs/" + gcsFilename.getBucketName() + "/" + gcsFilename.getObjectName());

ImagesService images = ImagesServiceFactory.getImagesService();
    GcsFilename gcsFilename = new GcsFilename(myBucket, myFileName);
    BlobstoreService blobstore = BlobstoreServiceFactory.getBlobstoreService();
    BlobKey blobKey = blobstore.createGsBlobKey(key);
    ServingUrlOptions opts = ServingUrlOptions.Builder.
            withBlobKey(blobKey).
            secureUrl(true);
    images.getServingUrl(opts);

当我执行其中一个代码时，我得到了这个错误：

  

线程“main”中的异常com.google.apphosting.api.ApiProxy $ CallNotFoundException：找不到API包'blobstore'或调用'CreateEncodedGoogleStorageKey（）'。

有什么想法吗？

我发现的解决方案：

String key = ""; // Such as /gs/example-bucket/categories/animals.png"
ImagesService images = ImagesServiceFactory.getImagesService();
BlobstoreService blobstore = BlobstoreServiceFactory.getBlobstoreService();
BlobKey blobKey = blobstore.createGsBlobKey(key);
ServingUrlOptions opts = ServingUrlOptions.Builder.
        withBlobKey(blobKey).
        secureUrl(true);
return images.getServingUrl(opts);
