嗨，我想知道我是否可以不基于用户输入，而是基于从其他地方派生的对象进行验证。例如，我有这样一个对象：

userDetails{
  "id":1,
  "surname":"Wood",
  "firstName":"Victor"
}

我有一个这样的“是”验证

export const userDetailValidation= Yup.object().shape({
  surname: Yup.string().
         .required("This field is required.")
         .max(50, "Maximum character is 50.")
  firstName: Yup.string().
         .required("This field is required.")
         .max(50, "Maximum character is 50.")
});

我可以做些什么来验证基于Yup Validation的对象？
