How to Create Google Cloud Storage Signed Urls on App Engine Python

Question

I couldn\'t find a simple example on how to implement Google Cloud Storage Signed Urls on Google App Engine with Python. Please write a step by step guide. :)

Answer 1

I created this repo: https://github.com/voscausa/appengine-gcs-signed-url

Using GAE Pyrthon app_identity.get_service_account_name() and app_identity.sign_blob() makes creating signed url's very easy, without using a PEM key. The app shows how to download a GCS file.

But if you use the SDK to test the app, you have to use:

1. --appidentity_email_address
2. --appidentity_private_key_path

because creating a signed url is not part of the GCS client.
