HarmonyOS鸿蒙Next中快应用有获取文件摘要值的接口吗？

问题背景

快应用有获取文件摘要值的接口吗？例如我想获取文件的SHA256或者MD5值。

解决方法

快应用规范没有提供此功能的接口，但是可以使用第三方库crypto-js来获取。
检查快应用项目目录下是否已经有第三方库依赖文件package.json。如果没有，在华为快应用IDE中启动第三方依赖库：菜单选择“NPM > Start Npm Library”，执行完成，将生成package.json。
切换至IDE控制台的“TERMINAL”页签，进入快应用项目的根目录，输入安装命令npm i -S crypto-js，安装crypto-js库。
