I want to get the BlobKey from a file a user has uploaded to link the
BlobKey to other information.
First I retrieve a post URL to upload the blob:
val blobstoreService = BlobstoreServiceFactory.getBlobstoreService
return blobstoreService.createUploadUrl("/")
Than I do a simple doPost() to post the file to the retrieved post
URL. But doPost is a void method and don't provide any return value.
Is there a method which provides a return value (the BlobKey) for the
file that was uploaded?
