How do I access http.Request data?

Hello, trying to make goa work and need to report on the source IP. How do I access http.Request data in particular RemoteIP.

Hello, there are a couple of approaches that could work here:

1. Simply map the payload attribute to the corresponding HTTP header, see HTTP Transport Mapping
2. Use a HTTP middleware similar to the Goa PopulateRequest middleware to load the HTTP request elements into the context. The method can then extract the value(s) from the context.
3. Combine #2 with a server interceptor to initialize the payload attribute from the value in the context so that it is completely transparent to the business logic.
