如何获取 app.json5 配置文件中的应用配置信息

let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATION;  
try {  
  bundleManager.getBundleInfoForSelf(bundleFlags).then((data) => {  
    this.context.resourceManager.getStringValue(data.appInfo.labelId, (error, value) => {  
      if (error != null) {  
      } else {  
        hilog.info(0x0000, 'testTag', 'getBundleInfoForSelf successfully. Data: %{public}s', JSON.stringify(value));  
      }  
    })  
    hilog.info(0x0000, 'testTag', 'getBundleInfoForSelf successfully. Data: %{public}s', JSON.stringify(data));  
  })  
} catch (err) {  
  hilog.error(0x0000, 'testTag', 'getBundleInfoForSelf failed: %{public}s', err.message);  
}
