package main import ( "encoding/json" "log" "reflect" "github.com/sanity-io/litter" ) func main() { type Item struct { Id int `json:"id"` Num int `json:"num"` } var itemMap = make(map[int]*Item) itemMap[1] = &Item{Id:1, Num:100} data, err := json.Marshal(itemMap) if err != nil { log.Println(err.Error()) return } targetItem := make(map[int]*Item) // must pass pointer // json.Unmarshal(data, targetItem) will no use, just a copy of targetItem.. json.Unmarshal(data, &targetItem) litter.Dump(targetItem) litter.Dump(reflect.DeepEqual(targetItem, itemMap)) } output: map[int]*main.Item{ 1: &main.Item{ Id: 1, Num: 100, }, } true
