在RPC调用中确定请求者的IP地址

Question

In Go using the standard net/rpc functionality, I would like to determine what the IP address an inbound RPC request is coming from. The underlying http functionality appears to provide this in the http.Request object, but I cannot see any way of getting at that from the default RPC handler (set using rpc.HandleHTTP).

Is there some hidden mechanism for getting at the underlying http.Request, or do I have to do something fancier with setting up a different HTTP responder?

You can also use https://github.com/valyala/gorpc instead of net/rpc, which passes client address to RPC server handler - see http://godoc.org/github.com/valyala/gorpc#HandlerFunc for details.
