rename key

[baxiry]

Is there a way to rename key?
e.g :

{"name":"adam"} become {"first_name":"adam"}

thanks

I have same question

@AnonimBella

// reKey renames json feild
func reKey(oldkey, newkey, json string) string {

	list := []string{}

	gjson.Parse(json).ForEach(func(key, value gjson.Result) bool {

		if key.Str == oldkey {
			list = append(list, newkey+siparator+value.String())

		} else {
			list = append(list, key.String()+siparator+value.String())
		}

		return true
	})

	slice := []string{}

	res := "{"
	for _, v := range list {
		if string(v[len(v)-1]) == "}" {
			continue
		}

		slice = strings.Split(v, siparator)

		if gjson.Parse(slice[1]).Type == 2 {
			res += `"` + slice[0] + `":` + slice[1] + `,`
			continue
		}
		res += `"` + slice[0] + `":"` + slice[1] + `",`
	}

	return res[:len(res)-1] + `}`
}

I'm using this function temporarily, it works fine. There are ways I can make it more efficient, I'm thinking of rewriting it later.
