Building RESTful Web services with Go

Let us create a simple RPC server that sends the UTC server time back to the RPC client. First, we start with the server.

The RPC server and RPC client should agree upon two things:

1. Arguments passed
2. Value returned

The types for the preceding two parameters should exactly match for both server and client:

package mainimport (    "log"    "net"    "net/http"    "net/rpc"    "time")type Args struct{}type TimeServer int64func (t *TimeServer) GiveServerTime(args *Args, reply *int64) error {    // Fill reply pointer to send the data back    *reply = time.Now().Unix()    return nil}func main() {    // Create a new RPC server    timeserver := new(TimeServer)    // Register RPC server    rpc.Register(timeserver)    rpc.HandleHTTP() // Listen for requests on port ...
