An HTTP server in Go kit

The true value of Go kit becomes apparent when we create an HTTP server for our endpoints to hash and validate.

Create a new file called server_http.go and add the following code:

package vault 
import ( 
  "net/http" 
  httptransport "github.com/go-kit/kit/transport/http" 
  "golang.org/x/net/context" 
) 
func NewHTTPServer(ctx context.Context, endpoints
 Endpoints) http.Handler { 
  m := http.NewServeMux() 
  m.Handle("/hash", httptransport.NewServer( 
    ctx, 
    endpoints.HashEndpoint, 
    decodeHashRequest, 
    encodeResponse, 
  )) 
  m.Handle("/validate", httptransport.NewServer( 
    ctx, 
    endpoints.ValidateEndpoint, 
    decodeValidateRequest, 
    encodeResponse, 
  )) 
  return m 
} 

We are importing the github.com/go-kit/kit/transport/http package and (since we're also importing the net/http package) telling Go that we're going to explicitly refer to this package as httptransport.

We are using the NewServeMux function from the standard library to...
