如何获取当前HAP的包名

import bundleManager from '@ohos.bundle.bundleManager'; 
import { BusinessError } from '@ohos.base'; 
import hilog from '@ohos.hilog'; 
let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_DEFAULT; 
try { 
    bundleManager.getBundleInfoForSelf(bundleFlags).then((data) => { 
        hilog.info(0x0000, 'testTag', 'getBundleInfoForSelf successfully. Data: %{public}s', JSON.stringify(data)); 
    }).catch((err: BusinessError) => { 
        hilog.error(0x0000, 'testTag', 'getBundleInfoForSelf failed. Cause: %{public}s', err.message); 
    }); 
} catch (err) { 
    let message = (err as BusinessError).message; 
    hilog.error(0x0000, 'testTag', 'getBundleInfoForSelf failed: %{public}s', message); 
}
