HarmonyOS resources/profile下面自定义的json如何读取并使用？

"metadata": [  
      {  
        "name": "com.bb.aa",  
        "resource": "$profile:config"  
      }  
    ]

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){  
        let r = metadata.resource;  
  
        hilog.info(0x0000, 'testTag', 'MetaData resource: %{public}s', JSON.stringify(r));  
      }  
    }  
  }).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);  
}
