如何获取app配置的版本信息

Answer 1

三方应用：可以通过getBundleInfoForSelf获取自身的应用包信息，其中入参bundleFlags指定所返回的BundleInfo中所包含的信息。

![](b8c882ff92355024ffbb446090f27675.emf)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);   
}
