HarmonyOS navigation跳转参数获取

方式1：

build() {
  NavDestination() {
    Column() {
      Text("PageOne组件")
        .fontSize(50)
        .fontWeight(FontWeight.Bold)
      ...
    }
    // .mode(NavDestinationMode.DIALOG)
    .title("PageOne组件")
    .onReady((context: NavDestinationContext) => {
      this.pageInfos = context.pathStack
      console.log('param=', JSON.stringify(context.pathInfo.param))
    })
  }

  this.registerInterception();
}
