Amazon S3 expiring URLs with Boto

If you’re using the Boto python wrapper for the Amazon S3 service, you can quickly generate temporary URLs for your private files.

from boto.s3.connection import S3Connection   s3 = S3Connection('YOUR_KEY', 'YOUR_SECRET', is_secure=False) url = s3.generate_url(60, 'GET', bucket='YOUR_BUCKET', key='YOUR_FILE_KEY', force_http=True)

This will give you a URL to your private file on S3 that will only work for 60 seconds. It will look something like this:
