用户可以不经身份验证直接将文件上传到Google Cloud Storage吗？

Question

I just set up a simple JS photo uploader on my site. It uploads photos directly to a Google Cloud Storage bucket.

I used the code from their official JavaScript library

But if you look at that code, you'll see that it requires authentication. I'm authenticated and able to upload photos, but I want everyone to be able to just upload their files without signing in to their Google Accounts.

Is that possible?

Answer 1

You could use a POST policy doc: https://cloud.google.com/storage/docs/xml-api/post-object#policydocument

This will let you build a signed request with various constraints built in (content-length, content-size, etc.), allowing unauthenticated users to upload to your bucket with the given constraints.
