Go中interface{}转化为[]interface{}

func ToSlice(arr interface{}) []interface{} {
	ret := make([]interface{}, 0)
	v := reflect.ValueOf(arr)
	if v.Kind() != reflect.Slice {
		ret = append(ret, arr)
		return ret
	}
	l := v.Len()
	for i := 0; i < l; i++ {
		ret = append(ret, v.Index(i).Interface())
	}
	return ret
}
