HarmonyOS 如何遍历interface

当前无法直接遍历interface，建议创建相应类型的对象后再进行遍历，参考代码如下：

import { promptAction } from '@kit.ArkUI';

@Entry
@Component
struct Index {
  @State message: boolean = false;

  get() {
    console.log(`keys: ${Object.keys(myObj)}`)
  }

  build() {
    Column() {
      Button('点击').onClick(() => {
        this.get()
        promptAction.showToast({ message: `判断结果：${this.message}` })
      })
    }.width('100%').height('100%').justifyContent(FlexAlign.Center)
  }
}

export interface ISignDataModel {
  localId?: string;
  date?: string | null;
  tag?: string | null;
}

interface MyInterface {
  prop1: string;
  prop2: number;
}

const myObj: MyInterface = {
  prop1: "Hello",
  prop2: 42,
};
