HarmonyOS 如何获取相册里照片的地理位置信息

试了相机拍照，查看图库照片详情，没有显示出拍摄地点
自己拍摄的图片, 查看文档 PHOTO_KEY 枚举类型里面无地理位置信息关键字

是否有方法支持获取图片位置信息

HarmonyOS

请确认拍照时开启了网络和定位，参考如下代码获取：通过picker获取图片uri：

// 调用PhotoViewPicker.select选择图片
async function photoPickerGetUri() {
  try {

    PhotoSelectOptions.MIMEType = photoAccessHelper.PhotoViewMIMETypes.IMAGE_TYPE;
    PhotoSelectOptions.maxSelectNumber = 15;
    // PhotoSelectOptions.isEditSupported=true;
    let photoPicker = new photoAccessHelper.PhotoViewPicker();
    photoPicker.select(PhotoSelectOptions).then((PhotoSelectResult: photoAccessHelper.PhotoSelectResult) => {
      console.info('PhotoViewPicker.select successfully, PhotoSelectResult uri: ' + JSON.stringify(PhotoSelectResult));
      uris = PhotoSelectResult.photoUris;
      // photoPicker.preSelectUris=uris;
      PhotoSelectOptions.preselectedUris=uris;
      console.info('photoViewPicker.select to file succeed and uris are:' + uris);
    }).catch((err: BusinessError) => {
      console.error('PhotoViewPicker.select failed with err: ' + JSON.stringify(err));
    });
  } catch (error) {
    let err: BusinessError = error as BusinessError;
    console.error('PhotoViewPicker failed with err: ' + JSON.stringify(err));
  }
}
//根据uri创建imagegesource，获取ImageProperty属性：
async pixelMap(){
  let file = fs.openSync(uris[0], fs.OpenMode.READ_ONLY);
  console.info(`TestAlbum asset: uri=${uris[0]}`)

  console.info('file fd: ' + file.fd);
  //根据文件fd创建imagSource
  const imageSource: image.ImageSource = image.createImageSource(file.fd);
  let options: image.ImagePropertyOptions = { index: 0, defaultValue: '0' }
  //完成后关闭fd
  fs.closeSync(file);
  const latitude: string = await imageSource.getImageProperty(image.PropertyKey.GPS_LATITUDE, options);
  const longitude: string = await imageSource.getImageProperty(image.PropertyKey.GPS_LONGITUDE, options);
  const ooo: string = await imageSource.getImageProperty(image.PropertyKey.ORIENTATION, options);
  const ImageDescription: string =
    await imageSource.getImageProperty(image.PropertyKey.IMAGE_DESCRIPTION, options);
  console.info(`TestAlbum asset: uri=${uris[0]}, latitude=${latitude}, longitude=${longitude}},ooooo=${ooo}`)
  console.info('TestAlbum asset ' + ImageDescription);
}
