The server{} block you provided is http-only, not https.  On the 
other hand, what you ask about needs correct configuration of two 
server blocks, one for http, and another one for https.

Here is an example:

    server {
        listen 80;
        server_name www.example.com;

        location / {
            # we are in http server, but want https for normal 
            # requests - redirect to https

            return 301 https://$host$request_uri;
        }

        location /http_only_service {
            ... do real work here ...
        }
    }

    server {
        listen 443 ssl;
        server_name www.example.com;

        ssl_certificate ...
        ssl_certificate_key ...

        location / {
            ... do real work here ...
        }

        location /http_only_service {
            # this is http only service, but we are in https 
            # server - redirect to http

            return 301 http://$host$request_uri;
        }
    }
 
Hope this helps.
