HarmonyOS 配置文件中metadata如何读取？

let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_METADATA | 
bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATION; 
try { 
  bundleManager.getBundleInfoForSelf(bundleFlags).then((bundleInfo: bundleManager.BundleInfo) => { 
    hilog.info(0x0000, ‘testTag’, ‘getBundleInfoForSelf successfully. Data: %{public}s’, JSON.stringify(bundleInfo)); 
    hilog.info(0x0000, ‘testTag’, ‘getBundleInfoForSelf successfully. MetaData: %{public}s’, JSON.stringify(bundleInfo.appInfo.metadataArray)); 
    let arr = bundleInfo.appInfo.metadataArray; 
    console.info("testTag arr is ", (arr instanceof Array)); 
    hilog.info(0x0000, ‘testTag’, ‘arr : %{public}s’, JSON.stringify(arr.length)); 
    for(let data of arr){ 
      hilog.info(0x0000, ‘testTag’, ‘MetaData name: %{public}s’, JSON.stringify(data.moduleName)); 
      for(let metadata of data.metadata){ 
        hilog.info(0x0000, ‘testTag’, ‘MetaData content: %{public}s’, JSON.stringify(metadata)); 
      } 
    } 
  }).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); 
},
