JSON响应为整数，但为空时为字符串

I am unmarshalling a JSON response into a struct. For one of the fields, it returns an int and a string when empty.

type example struct {    
  Position int `json:"position"`
}

json: cannot unmarshal string into Go struct field .position of type int

The response is either

{"position":8} or {"position":"none"}

How can I handle both an int and string response?

Change the type to interface{}, and then you can check the type at runtime.

type example struct {    
    Position interface{} `json:"position"`
}
/*
Returns an int and a bool, indicating if a position exists.
*/
func (e * example) getValue() (int,bool){
    if v,ok := Position.(int) {
      return v,true
    } else {
     return 0,false
    }
}
