cloud storage authentication for non google users

[Filip Delperdange]

Hello,

We are building an application through which users will be able to access protected resources.  (images, documents ...). These images and documents will be loaded by the web browser

We manage user authentication in the application.

We would like to store these resources on google cloud storage and load them directly from google cloud storage into the web browser

But how can we authorize the access to this resources on google cloud storage so that only our users browser can upload these resources?

Thx,

Filip.

Hello,

I understand that you would like to authorize web pages to upload images (objects) to Cloud Storage. I was able to find a document here, indicating that the best way to do this is using signed policy documents[1][2]. You may see an example here[3]. A policy document would allow an HTML form to upload files into the target bucket.

Hello,

Thx for the feedback!

It is not only uploading, but also retrieving and showing in the browser.

Only authenticated users should be able to retrieve images and documents from the the bucket.

They are authenticated by another application (so not google users).  So somehow I would like generate a token that would allow the user to retrieve data from a specific bucket.

kr,

Filip.
