HarmonyOS 沙盒中的图片和视频移动/拷贝到系统相册中？

Question

应用中生成了一张图片/视频文件，需要在系统相册中能看到这图片和视频，fs.moveFile只支持沙盒内文件路径的移动，是否有其他方案，是否有相关代码demo

Answer 1

视频保存到相册方法，入参为视频的沙箱路径

async  videoWriteAlbumExample2(fileUri:string) {
    console.info('createVideoAssetRequestDemo:' + fileUri);
    let context = getContext(this);
    try {
      // 需要确保fileUri对应的资源存在
      let phAccessHelper = photoAccessHelper.getPhotoAccessHelper(context);
      let assetChangeRequest: photoAccessHelper.MediaAssetChangeRequest = photoAccessHelper.MediaAssetChangeRequest.createVideoAssetRequest(context, fileUri);
      await phAccessHelper.applyChanges(assetChangeRequest);
      console.info('apply createVideoAssetRequest successfully');
      promptAction.showToast({
        message: '已保存至相册',
        duration: 2500
      });
    } catch (err) {
      console.error(`createVideoAssetRequestDemo failed with error: ${err.code}, ${err.message}`);
      promptAction.showToast({
        message: '保存失败',
        duration: 2000
      });
    }
  }

图片保存到相册方法，入参为图片的沙箱路径

async  imageWriteAlbumExample2(fileUri:string) {
    console.info('createImageAssetRequestDemo:' + fileUri);
    let context = getContext(this);
    try {
      // 需要确保fileUri对应的资源存在
      let phAccessHelper = photoAccessHelper.getPhotoAccessHelper(context);
      let assetChangeRequest: photoAccessHelper.MediaAssetChangeRequest = photoAccessHelper.MediaAssetChangeRequest.createImageAssetRequest(context, fileUri);
      await phAccessHelper.applyChanges(assetChangeRequest);
      console.info('apply createVideoAssetRequest successfully');
      promptAction.showToast({
        message: '已保存至相册',
        duration: 2500
      });
    } catch (err) {
      console.error(`createVideoAssetRequestDemo failed with error: ${err.code}, ${err.message}`);
      promptAction.showToast({
        message: '保存失败',
        duration: 2000
      });
    }
  }
