拉起的B应用接收的信息： 
在B应用中EntryAbility文件中onCreate()或者onNewWant()生命周期回调文件中接收EntryAbility传递过来的参数 
onNewWant(want: Want, launchParam: AbilityConstant.LaunchParam) { 
  let funcAbilityWant = want; 
  AppStorage.set('want', funcAbilityWant); 
  console.log(`onNewWant, want: ${want.abilityName}`); 
  console.log(`onNewWant, launchParam: ${JSON.stringify(launchParam)}`);
