UnmarshalJSON bug
UnmarshalJSON 无法反序列化自定义类型
func TestSetForm(t *testing.T) {
val := `{"id":"mQgb9MXL","lv":1,"itemId":111,"inFms":[1]}`
t.Log("val", val)
type Soldier struct {
Id string //唯一id
Lv int //等级
ItemId int //物品表的id
InFms slices.Set //在那几个阵型中
}
so := Soldier{}
err:=jsoniter.Unmarshal([]byte(val), &so)
t.Log(so,err)
}
type Set map[interface{}]struct{}

}
func (s Set) IsMembers(m interface{}) bool {

return ok
}
func (s *Set) UnmarshalJSON(text []byte) error {
if len(text) == 0 {
return nil
}
var i interface{}
err := jsoniter.Unmarshal(text, &i)
if err != nil {
return nil
}
*s = SetForm(i)
return nil

func (s *Set) MarshalJSON() (text []byte, err error) {

}
最终 无法反序列化inFms字段。 换成标准库后反序列化成功
