如何获取应用配置的versionCode和versionName

import { bundleManager } from '@kit.AbilityKit'; 
import { hilog } from '@kit.LancetKit'; 
import { BusinessError } from '@kit.BasicServicesKit'; 
 
let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_DEFAULT; 
try { 
  bundleManager.getBundleInfoForSelf(bundleFlags).then((data) => { 
    const versionCode = data.versionCode; 
    const versionName = data.versionName; 
    hilog.info(0x0000, 'testTag', `successfully. versionCode: ${versionCode}, versionName: ${versionName}`);     
  }).catch((err: base.BusinessError) => { 
    hilog.error(0x0000, 'testTag', 'failed. Cause: %{public}s', err.message); 
  }); 
} catch (err) { 
  hilog.error(0x0000, 'testTag', 'failed: %{public}s', err.message); 
}
