我有一个JSON我需要做一些处理.它使用我需要以某种方式引用的切片,以便在函数末尾修改Room-struct.如何以引用类型的方式同时使用此结构?

type Window struct {
Height int64 `json:"Height"`
Width int64 `json:"Width"`
}
type Room struct {
Windows []Window `json:"Windows"`
}
func main() {
js := []byte(`{"Windows":[{"Height":10,"Width":20},{"Height":10,"Width":20}]}`)
fmt.Printf("Should have 2 windows: %v\n", string(js))
var room Room
_ = json.Unmarshal(js, &room)
var wg sync.WaitGroup
// Add many windows to room
for i := 0; i < 10; i++ {
wg.Add(1)
go func() {
defer wg.Done()
addWindow(room.Windows)
}()
}
wg.Wait()
js, _ = json.Marshal(room)
fmt.Printf("Sould have 12 windows: %v\n", string(js))
}
