Overview

Package gjson provides convenient API for JSON/XML/INI/YAML/TOML data handling.

Example (ConversionGetStruct) 
package main

import (
	"fmt"
	"github.com/gogf/gf/encoding/gjson"
)

func main() {
	data :=
		`{
        "users" : {
            "count" : 1,
            "array" : ["John", "Ming"]
        }
    }`
	if j, err := gjson.DecodeToJson(data); err != nil {
		panic(err)
	} else {
		type Users struct {
			Count int
			Array []string
		}
		users := new(Users)
		if err := j.GetStruct("users", users); err != nil {
			panic(err)
		}
		fmt.Printf(`%+v`, users)
	}

}

Output:

&{Count:1 Array:[John Ming]}
Example (ConversionNormalFormats) 
package main

import (
	"fmt"
	"github.com/gogf/gf/encoding/gjson"
)

func main() {
	data :=
		`{
        "users" : {
            "count" : 1,
            "array" : ["John", "Ming"]
        }
    }`

	if j, err := gjson.DecodeToJson(data); err != nil {
		panic(err)
	} else {
		fmt.Println("JSON:")
		fmt.Println(j.MustToJsonString())
		fmt.Println("======================")

		fmt.Println("XML:")
		fmt.Println(j.MustToXmlString())

		fmt.Println("YAML:")
		fmt.Println(j.MustToYamlString())
		fmt.Println("======================")

		fmt.Println("TOML:")
		fmt.Println(j.MustToTomlString())
	}

}

Output:

JSON:
{"users":{"array":["John","Ming"],"count":1}}
======================
XML:
<users><array>John</array><array>Ming</array><count>1</count></users>
======================
YAML:
users:
    array:
        - John
        - Ming
    count: 1

======================
TOML:
[users]
  array = ["John", "Ming"]
  count = 1.0
