How to enable automatic download of blob from link

Ben Kaplan 0

I want to send a link to a blob that automatically downloads when the user navigates to the link. I know that you can set the CONTENT-DISPOSITION field to attachment; filename="dummy.csv" to cause the file to download. However this only works if you send the file with a SAS token.

Without a SAS token URL the user receives an error of PublicAccessNotPermitted

I would like to avoid SAS tokens as much as possible because they expire and they can be leaked. Instead, I would like to use managed identities (either actual users from Entra, or User Assigned Managed Identities).

How can I make the file automatically download with a managed identity?

@Ben Kaplan If you’re using Azure PowerShell, you can download a blob to your Azure Windows Virtual Machine using the managed identity as follows:

I am trying to do this using JavaScript in the browser. I would like the user to be able to download a blob without needing a SAS in the URL.
