How to pass the username&password while download file from Web Url?

I have secured downloadable link to download the file. So configured the link in InvokeHTTP processor with StandardSSLContextService with the truststore certificate. In response, I get the HTML tags i.e., page source of the link.

But using RestClient opensource if I logged into the link, data is downloading properly. If the link is not logged into the link, page source html tag is the result.

I think the similar behavior achieved in InvokeHTTP? How to resolve this to accept the credentials of the link? I have configured the username and password in InvokeHTTP but it fails.
