HarmonyOS interface里的属性支持改别名吗？

import { promptAction } from '@kit.ArkUI';  
@Entry  
@Component  
struct Index2 {  
  @State message: string = 'Hello World';  
  @State jsonStr: string =

  parse(st: string) {  
    let list = JSON.parse(st) as Record<string, string>  
    console.log('list:' + JSON.stringify(list))  
    console.log('720p:' + JSON.stringify(list['data']['play_info']['720p']))  
  }  
  build() {  
    Column() {  
      Button('点击一下').onClick(() => {
