HarmonyOS 鸿蒙Next context.startAbility能否指定page

context.startAbility跳转新的ability，新的ablity可以接收相关参数，可使用Want作为载体传递数据。

//在指定启动的CommonAbility中的onCreate()生命周期函数中将传递过来的参数信息保存下来。
export default class CommonAbility extends Ability {
onCreate(want, launchParam) {
AppStorage.SetOrCreate("WANT_PAGE",want)
}
}
//在指定启动的CommonAbility中窗口创建时，将保存的页面参数取出，并加载该页面。
export default class CommonAbility extends Ability {
onWindowStageCreate(windowStage: Window.WindowStage) {
// Main window is created, set main page for this ability
//设置默认加载页面
let firstPage = “pages/index”;
let want = AppStorage.Get(“WANT_PAGE”) as Want;
if(want.hasOwnProperty(“uri”)){
firstPage = want.uri;//加载指定页面
}
windowStage.loadContent(firstPage, (err, data) => {
if (err.code) {
hilog.isLoggable(0x0000, ‘testTag’, hilog.LogLevel.ERROR);
hilog.error(0x0000, ‘testTag’, ‘Failed to load the content. Cause: %{public}s’, JSON.stringify(err) ?? ‘’);
return;
}
hilog.isLoggable(0x0000, ‘testTag’, hilog.LogLevel.INFO);
hilog.info(0x0000, ‘testTag’, ‘Succeeded in loading the content. Data: %{public}s’, JSON.stringify(data) ?? ‘’);
});
}
}
