HarmonyOS 如何获取媒体库的相册文件夹名称，url等相关数据

可以先使用getAlbums获取相册列表，相册列表中有albumName参数。

参考文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-photoaccesshelper-V5#getalbums

可以参考以下代码：

this.phAccessHelper.getAlbums(photoAccessHelper.AlbumType.SYSTEM, photoAccessHelper.AlbumSubtype.USER_GENERIC, fetchOptions, async (err, fetchResult) => {
  if (err) {
    console.error(`getAlbumsCallback failed with err: ${err.code}, ${err.message}`);
    return;
  }
  if (fetchResult === undefined) {
    console.error('getAlbumsCallback fetchResult is undefined');
    return;
  }
  let album = await fetchResult.getAllObjects();
  console.info('getAlbumsCallback successfully, albumName: ' + album[0].albumName,JSON.stringify(album));
  fetchResult.close();
});

使用getalbums方法需要在module.json5中配置权限：

{
  "name": "ohos.permission.READ_MEDIA",
  "usedScene": {
    "abilities": [
    "EntryAbility"
    ],
    "when": "inuse"
  },
   "reason": "$string:READ_MEDIA"
},
