#鸿蒙通关秘籍#如何在HarmonyOS中保存下载的文件并读取其内容？

import fs from '@ohos.file.fs';

function saveAndReadFile(buffer, fileName) {
  let pathDir = getContext().filesDir;
  let filePath = pathDir + "/" + fileName;
  
  let file = fs.openSync(filePath, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE);
  fs.writeSync(file.fd, buffer);
  fs.closeSync(file);
  console.log("文件已保存到：" + filePath);
  
  let content = fs.readTextSync(filePath);
  console.log("文件内容：" + content);
}

// 假设下载成功后的响应体已获得，调用该方法进行文件保存与读取
saveAndReadFile(resp.result as ArrayBuffer, "demo.txt");
