google app engine - GAE/python: How to parse multipart data file from Cloud Storage (GCS)? -

i uploading file gcs (input file webform) following gae/python code:-

fx = self.request.body_file gcs_file = gcs.open(_gcs_bucket_name + "new_file_name", 'w') gcs_file.write(fx.read())

i able retrieve uploaded data gcs following code

gcs_file = gcs.open(_gcs_bucket_name + "new_file_name", 'r') self.response.write(gcs_file.read())

since uploaded data multiform data, how extract original file name, , original file (binary data) gcs_file.read() ?

you can save file in gcs original file name

you can create small datastore db entity having data of original file name , reference file in gcs

why should original binary different?

if have managed download gcs can verify binary same.
