Hi,
If the download entpoint is an authorized endpoint, you have to include "enc_auth_token" query string parameter. You can get value of
enc_auth_tokenas we do here https://github.com/aspnetzero/aspnet-zero-core/blob/dev/angular/src/app/shared/layout/chat/chat-message.component.ts#L32 -

@ismcagdas What is the difference between including "enc_auth_token" query string parameter and Authorization header in http get request? Can I use either of them or are there some specific use cases fo each one of them?
