使用新的文件API有一个更好的解决方案: http://code.google.com/appengine/docs/python/blobstore/overview.html

from __future__ import with_statement
from google.appengine.api import files
from google.appengine.ext import blobstore

def get_blob_key(self, data, _type):
    # Create the file
    file_name = files.blobstore.create(mime_type = _type)

    # Open the file and write to it
    with files.open(file_name, 'a') as f:
        f.write(data)

    # Finalize the file. Do this before attempting to read it.
    files.finalize(file_name)

    # Get the file's blob key
    blob_key = files.blobstore.get_blob_key(file_name)
    return blob_key
