Impersonation in REST API Application
Junior Member Posts: 25 Join Date: 2/18/20 Recent Posts
Hi,

I want to get the username of the user connected to Liferay as well as the username usurped in my backend REST API Liferay application.

I saw this information is only accessible via the ThemeDisplay object, but I cannot get the content of this object in the method of my API, it is always null.

Is there another way to access this data? Currently I am using PortalUtil.getUser(httpServletRequest), but it still gives me the same username with or without usurpation.

Thanks for your help

Can you please elaborate, or put some code snippets? It's too hard to understand from what you said.

Do you attach the &doAsUserId=<ID> to the rest request? If it is there, it should work. You can get the real user id with this call:
long actingUserId = AuditRequestThreadLocal.getAuditThreadLocal().getRealUserId();
To make this more convenient, I have also created a feature request, but currently you are stuck with adding doAsUserId to each rest request.
