HarmonyOS 鸿蒙Next：Applinking冷启动情况，用windowStage.load动态加载启动页时能否传递参数到加载的页面内，是否有实现的样例代码

可以参考 1.在ability中声明并设置 LocalStorage 的值，在loadContent 时将LocalStorage 做为参数传，

export default class EntryAbility extends UIAbility {

  private localStorage:LocalStorage=new LocalStorage()

  onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {

    hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onCreate');

    let targetPageType=want?.parameters?.['targetPageType']

    this.localStorage.setOrCreate('targetPageType',targetPageType)

  }

  onWindowStageCreate(windowStage: window.WindowStage): void {

    // Main window is created, set main page for this ability

    hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onWindowStageCreate');

    windowStage.loadContent('pages/Index',this.localStorage, (err) => {

      if (err.code) {

        hilog.error(0x0000, 'testTag', 'Failed to load the content. Cause: %{public}s', JSON.stringify(err) ?? '');

        return;

      }

      hilog.info(0x0000, 'testTag', 'Succeeded in loading the content.');

    });

  }

2.在ets中接受参数，如果ts中没有设置，就会使用默认值，pageType的默认值是空字

let storage=LocalStorage.GetShared()

@Entry(storage)

struct Index{

@LocalStorageLink('targetPageType') pageType:string=''
