should be able to change hostname of generated URL #3140
Description
We are facing google storage access issue in China. We have a kind of proxy controller at our CDN (Fastly) which will serve files from google storage to avoid Chinese blockage of Google hostnames.
So I need CDN's host in resource URL instead of storage.googleapis.com. I checked code and found it is currently hardcoded in StorageImpl.signUrl(...). So it would be good if it is possible to configure it.
Currently, URL looks like: https://storage.googleapis.com//<file_path>?GoogleAccessId=accessID
And I want something like: https://my.custom.host.com//<file_path>?GoogleAccessId=accessID
