Hi,
Have you tried following the example in the docs of how to upload a blob?
http://code.google.com/appengine/docs/python/blobstore/overview.html#Uploading_a_Blob
Note that the handler is deriving from
blobstore_handlers.BlobstoreUploadHandler, and that they don't
directly get the uploaded data, rather they get a blob key.
