How can I consume this explicit value in my code? I don't even know what it's called so Google is really failing me at the moment. Here's what JSON's unmarshal function needs for example: type

问题 Is it possible to unmarshal JSON into a struct made from reflection without hardcoding the original type? package main import ( "fmt" "encoding/json" "reflect" ) type Employee struct { Firstname string `json:"firstname"` } func main() { //Original struct orig := new(Employee) t := reflect.TypeOf(orig) v := reflect.New(t.Elem()) //Reflected struct new := v.Elem().Interface().(Employee) // Unmarshal to reflected struct json.Unmarshal([]byte("{\"firstname\": \"bender\"}"), &new) fmt.Printf("%+v

问题 I have a service which provides me properties through REST. Now I want to unmarshal the body into a properties struct. Please see this playground example: click. When I have only one property, I can easily unmarshal it into a Property . However the ACTUAL response from the server is somehow difference.
