Когда я пытаюсь выполнить запись в blobstore, используя тот же пример, который приведен в документации (ниже), он работает каждый раз на сервере dev, но 100% времени завершает работу appppot с этой ошибкой: The API call file.Create() took too long to respond and was cancelled. Поиск в Google показывает, что этоэто редкая проблема, хотя некоторые сообщили об этом.Есть идеи, что здесь происходит?
Я использую Python 2.6 на сервере dev, поэтому, может быть, поэтому я не вижу этого во время разработки.
from __future__ import with_statement
from google.appengine.api import files
# Create the file
file_name = files.blobstore.create(mime_type='application/octet-stream')
# 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)
Traceback:
The API call file.Create() took too long to respond and was cancelled.
