HarmonyOS 怎么解析集合对象和解析jsonarray的

可参考以下代码：

export interface IShopDetailResult {
  categoryId : string
  description : string
  detail : string[]
  id : string
  images : string[]
  price : Number
  promotion : string
  specifications : string[]
  title : string
  imagesResource : Resource
}
export class ShopDetailResult implements IShopDetailResult {
  categoryId: string = ""
  description: string = ""
  detail: string[] = [""]
  id: string = ""
  images: string[] = [""]
  price: Number = 0
  promotion: string = ""
  specifications: string[] = [""]
  title: string = ""
  imagesResource : Resource
  constructor(props: ShopDetailResult) {
    this.categoryId = props.categoryId;
    this.description = props.description;
    this.detail = props.detail;
    this.id = props.id;
    this.images = props.images;
    this.price = props.price;
    this.promotion = props.promotion;
    this.specifications = props.specifications;
    this.title = props.title;
    this.imagesResource = props.imagesResource;
  }
}

以上是class类实现接口

let shopListResult = JSON.parse(JSON.stringify(shopList)) as Array<IShopDetailResult> 

这一步JSON.stringify(shopList)就是相当于json数据，as Array<IShopDetailResult>就是要转换的数组，这是转换的方式。同理，转换class成json的，JSON.stringify(shopList) as string，按照这样的转换方式即可。这个转换需要您参考jsonarray的json数据，自己建立class进行转换。另外，ArrayList并不是原生的类型，通常使用数组（Array）来代替 ArrayList。
