Go实现map转json的示例详解

package main
import (
	"encoding/json"
	"fmt"
)
func main() {
	Map2Json()
}
func Map2Json() {
	mapInstance := make(map[string]interface{})
	mapInstance["Name"] = "cs"
	mapInstance["Age"] = 28
	mapInstance["Address"] = "杭州"
	relation := make(map[string]interface{})
	relation["father"] = "cuixxxxxxx"
	relation["mother"] = "yinxxxxx"
	relation["wife"] = "pengxx"
	mapInstance["Relation"] = relation
	pet := make(map[string]interface{})
	pet["one"] = "弥弥懵"
	pet["two"] = "黄橙橙"
	pet["three"] = "呆呆"
	pet["four"] = "皮瓜瓜"
	pet["five"] = "斑斑"
	mapInstance["Cat"] = pet
	jsonStr, err := json.Marshal(mapInstance)
	fmt.Println("err is:", err)
	fmt.Println("jsonStr is:", string(jsonStr))
}
