Note on the downloading. You can invoke a download action without any popups or user interaction. The "traditional" workaround is to create a hyperlink dynamically and invoke the action, here's one of the examples: alfresco-ng2-components/download-zip.dialog.ts at master · Alfresco/alfresco-ng2-components · GitHub

We also got several helper functions to invoke the download of the raw data when fetched from the ACS/APS in the ContentService: alfresco-ng2-components/content.service.ts at master · Alfresco/alfresco-ng2-components · GitHub

You can refer to the code for some snippets or ideas how to do that with just js-api.

Hallo Denys,

thanks for your reply.

I am not sure if I understand your suggestion completely.

As far as I understood you would recommend generating an dynamic hyperlink to the raw URL of the content.

For example this URL can look like this: https://HOST/activiti-app/app/rest/content/2002/raw

I can generate such a url and show the hyperlink to the user. Then, the problem is, that the request is not authorized.

This is exactly the solution I've described with point 2 in my initial post. Maybe I do not get your suggestion at this point. When calling this URL with a REST client a HTTP401 is returned even when the Basic Auth is set.

Other requests like tasks/query are working fine this way.
