Golang - How to get an underlying type of a map using reflect pkg

map-type-reflect.go

package main

import (
	"fmt"
	"reflect"
)

type Map map[string]string

type Object struct {
	Items Map
}

func main() {

	obj := &Object{}

  	t := reflect.ValueOf(obj).Elem().FieldByName("Items").Type()

	// The below gives me 'main.Map' type. But I want to get the
	// underlying type of 'map[string]string'... How?

	fmt.Printf("From:\t%v\n", t)
	fmt.Println("I want:\tmap[string]string")

	// Reflection again..
	
	if (t.Kind() == reflect.Map) {
		fmt.Printf("Got:\t%v", reflect.MapOf(t.Key(), t.Elem()))
	}
}
