標準的就簡單通用。

package main

import (
	"encoding/json"
	"fmt"
	"log"
)

	
func main() {
	c := make(map[string] interface{})
	c["name"] = "Gopher"
	c["title"] = "programmer"
	c["contack"] = map[string] interface{} {
		"home": "412323",
		"cell": "5223.222.22",
	}
	
	data, err := json.MarshalIndent(c, "", "  ")
	if err != nil {
		log.Println("ERROR:", err)
		return
	}
	
	fmt.Println(string(data))
}

Go語言標準包之json編碼
