this.pageStack.setInterception({
  willShow: (from: NavDestinationContext | "navBar", to: NavDestinationContext | "navBar",
    operation: NavigationOperation, animated: boolean) => {
    if (typeof to === "string") {
      console.log("target page is navigation home page.");
      return;
    }
    // 将跳转到PageTwo的路由重定向到PageOne
    let target: NavDestinationContext = to as NavDestinationContext;
    if (target.pathInfo.name === 'PageTwo') {
      target.pathStack.pop();
      target.pathStack.pushPathByName('PageOne', null);
    }
  }
})
