HarmonyOS share kit中传递图片路径该如何传呢？

Question

uri路径该如何传？我现在在cache dir中保存了一个图片，直接使用cache路径保存失败

Answer 1

参考以下demo，filePath是cache路径。

/** 图片分享 */
private async handelImageShare(): Promise<void> {
  const contextFaker: Context = getContext(this);
  let filePath = contextFaker.filesDir + '/exampleImage.jpg';
  let shareData: systemShare.SharedData = new systemShare.SharedData({
    utd: utd.UniformDataType.IMAGE,
    uri: fileUri.getUriFromPath(filePath),
    title: '图片标题', // 不传title字段时,显示图片文件名
    description: '图片描述' // 不传description字段时,显示图片大小
  });
  let controller: systemShare.ShareController = new systemShare.ShareController(shareData);
  let context = getContext(this) as common.UIAbilityContext;
  controller.show(context, {
    previewMode: this.imagePreviewMode == 0 ? systemShare.SharePreviewMode.DEFAULT : systemShare.SharePreviewMode.DETAIL
  });
}
