HarmonyOS如何获取用户相册所有目录？

鸿蒙如何获取用户相册所有目录？

业务场景：需要读取到当前用户下的所有图片，实现应用内部自定义图片列表，双框架可以通过云闪付登录后，首页右上角扫一扫 —> 相册进入

参考官网文档https://developer.huawei.com/consumer/cn/doc/harmonyos-guides/photoaccesshelper-overview-0000001821000253

通过photoAccessHelper，本地跑不通[nodict]MediaLibraryNapiUtils:{HandleError:641} Error: GetPhotoAlbums medialibrary inner fail, js errcode:14000011

代码如下：

let context = getContext(this); 
let phAccessHelper = photoAccessHelper.getPhotoAccessHelper(context); 
let albumPredicates: dataSharePredicates.DataSharePredicates = new dataSharePredicates.DataSharePredicates(); 
let albumName: photoAccessHelper.AlbumKeys = photoAccessHelper.AlbumKeys.ALBUM_NAME; 
albumPredicates.equalTo(albumName, ‘albumName’); 
let albumFetchOptions: photoAccessHelper.FetchOptions = { 
  fetchColumns: [], 
  predicates: albumPredicates 
}; 
 
let photoPredicates: dataSharePredicates.DataSharePredicates = new dataSharePredicates.DataSharePredicates(); 
let photoFetchOptions: photoAccessHelper.FetchOptions = { 
  fetchColumns: [], 
  predicates: photoPredicates 
}; 
 
try { 
let albumFetchResult: photoAccessHelper.FetchResult<photoAccessHelper.Album> = await phAccessHelper.getAlbums(photoAccessHelper.AlbumType.USER, photoAccessHelper.AlbumSubtype.USER_GENERIC, albumFetchOptions); 
let album: photoAccessHelper.Album = await albumFetchResult.getFirstObject(); 
console.info('getAlbums successfully, albumName: ’ + album.albumName); 
let photoFetchResult = await album.getAssets(photoFetchOptions); 
let photoAsset = await photoFetchResult.getFirstObject(); 
console.info('album getAssets successfully, albumName: ’ + photoAsset.displayName); 
albumFetchResult.close(); 
photoFetchResult.close(); 
} catch (err) { 
console.error('album getAssets failed with err: ’ + JSON.stringify(err)); 
}

同时无法获取相机中的图片
