How to get FileInfo/gcs file_name for files uploaded via BlobstoreUploadHandler?

blobstore.parse_file_info(cgi.FieldStorage()['file']) method doesn't work for BlobstoreUploadHandler, the FieldStorage seems to be for regular uploads

There is no gcs filename information inside the blob_info that the regular blob_info from self.get_uploads provides

It seems only a blob_key can be accessed using the regular methods, however a gcs file_name seems to be the safest bet for future

How can I get gcs file_name of a file uploaded to an url from blobstore.create_upload_url with gs_bucket_name argument?

class UploadAPI(blobstore_handlers.BlobstoreUploadHandler):
    def post(self):
        file_info = self.get_file_infos()[0]

        rtn_data = {
            "filename": file_info.filename,
            "content_type": file_info.content_type,
            "creation": file_info.creation,
            "size": file_info.size,
            "md5_hash": file_info.md5_hash,
            "gs_object_name": file_info.gs_object_name
        }

I did find the usage in code, but I cannot find document either.

In https://developers.google.com/appengine/docs/python/blobstore/fileinfoclass said.

If you're using the webapp or webapp2 application framework, you can use the BlobstoreUploadHandler for more convenient parsing of this information.

But there is nothing related to FileInfo I can find in document of BlobstoreUploadHandler https://developers.google.com/appengine/docs/python/tools/webapp/blobstorehandlers
