HarmonyOS 返回原页面如何获取传递的参数

上层页面是如何跳转的 例：pushPath 入参有onPop回调 该回调可获取

Button('pushPath', { stateEffect: true, type: ButtonType.Capsule })
  .width('80%')
  .height(40)
  .margin(20)
  .onClick(() => {
    this.pageInfos.pushPath({ name: 'pageOne',onPop: (popInfo: PopInfo)=>{
      JSON.stringify("popInfo.result::"+popInfo.result)
      console.log('onPop回调执行了');
    } }) //将name指定的NavDestination页面信息入栈
  })
