以某种类型扩展接口属性

Question

我有以下界面：

export interface ProductInterface {
  id: number;
  ean: string;
  title: string;
  brand: string;
  shortdescription: string;
  fulldescription: string;
  image: string;
  weight: string;
  price: string;
  category: string;
  subcategory: string;
  subsubcategory: string;
}

我想创建一个扩展属性的类型

x.products.product.map((prod: Data) => ({
  id: prod._attributes.Id,
  ean: prod.ean._text,
  title: prod.title._text,
  brand: prod.brand._text,

type Data = ProductInterface & {
  _attributes: { Id: number };
  this: { _text: string };
};

这可能吗？

我解决了问题

interface ProductAttributes {
  _attributes: { Id: number };
}

type ProductText = { [P in keyof ProductInterface]: { _text: string } };

type ProductApiData = ProductAttributes & ProductText;
