[大数据]GoLang json格式化输出

简单记录一下go语言json格式化输出的办法

import (
	"bytes"
	"encoding/json"
	"fmt"
	"os"
)

type Complex_Type struct{
	Age int `json:"age"`
	Name string `json:"name"`
	Grades map[string]int `json:"grade"`
	Parents []string `json:"parents"`
}

	grades := map[string]int{
		"math" : 96,
		"chinese" : 87,
		"english" : 93,
	}

	parents := []string{
		"minato",
		"kushina",
	}

	complex_type := Complex_Type{
		Age: 18,
		Name: "Naruto",
		Grades : grades,
		Parents: parents,
	}
	res,err := json.Marshal(complex_type)
	exitOnError(err)
	var out bytes.Buffer
	err = json.Indent(&out,res,"","\t")
	out.WriteTo(os.Stdout)
	fmt.Printf("\n")

输出：
