import "github.com/gogf/gf/encoding/gjson"

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

Example (ConversionGetStruct)

Code: 

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)
    }
