golang实现json类型不确定时的转换

// convert json to struct
// type uncertain
package main
import (
 "fmt"
 "encoding/json"
)
type Host struct {
 Id interface{}
 IdcId interface{}
}
func main() {
 b := []byte(`{"ID": 11, "IDCid": "1001"}`)
 m := Host{}
 err := json.Unmarshal(b, &m)
 if err != nil {
 fmt.Println("Umarshal failed:", err)
 return
 }
 fmt.Printf("m:%#v\n", m)
}

m:main.Host{Id:11, IdcId:”1001”}}

type student struct {
 Name string   `json:"name"`
 Info interface{} `json:"info"`
}
