getServingUrl() Method using Google Cloud Storage value

Question

how would you create a basic URL for an image using getServingUrl() without using Blobs? All the examples I've seen so far involved blobs, but I need to use Google Cloud Storage value.

Thanks.

There is a new overload for getServingUrl() with a ServingUrlOptions method argument. And its builder has a withGoogleStorageFileName() method that you can use to create a URL based on the Cloud Storage filename.

GcsFilename gcsFilename = new GcsFilename("bucketName", "objectName");
ImagesService is = ImagesServiceFactory.getImagesService(); 
String filename = String.format("/gs/%s/%s", gcsFilename.getBucketName(), gcsFilename.getObjectName());
String servingUrl = is.getServingUrl(ServingUrlOptions.Builder.withGoogleStorageFileName(filename));
