I have a python App Engine app and save files using the Google Cloud Storage API. However I need to get the serving URL for each file.
On production it is easy to figure out what the serving URL is as I prepend http://commondatastorage.googleapis.com to /bucket/path/to/file.txt as I already have the bucket name and path to my file.
How do I figure out what the serving URL is on the dev server?
It seems straight forward enough to do this with images using images.get_serving_url which can now take either blobstore or Cloud Storage references.
How can I figure out the serving URL for all files, not just images in a way that is compatible with both the development and production App Engine environments?
