HarmonyOS 鸿蒙Next中Ability的windowStage.loadContent(pages MeetingPage)如何传递参数给page

在ability中声明并设置 LocalStorage 的值，在loadContent 时将LocalStorage 做为参数传

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.');
  });
}

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

let storage = LocalStorage.GetShared()
@Entry(storage) struct Index
{
  @LocalStorageLink('targetPageType') pageType: string = ''
}
