I want to set Content-Type metadata to image/jpeg for all objects of a Google Storage bucket.
How to do this?
回答1:
Using gsutil and its setmeta command:
gsutil -m setmeta -h "Content-Type:image/jpeg" gs://YOUR_BUCKET/**/*.jpg
Use the -m to activate a parallel update, in case you have a lot of objects.
The /**/* pattern will perform a recursive search on any folders that you may have on your bucket.
