Node.js と adb を使用して携帯電話のバックアップ ガジェットを開発する手順を段階的に説明します。

export const getConfig = (): ConfigType => {
  if (existConf()) {
    return readJsonSync(CONFIG_PATH);
  }
  // 找不到配置文件
  return createDefaultConfig();
};

(async () => {
  const device: string | boolean = await selectDevice();
  if (device) MIB();
})();

export const selectDevice = async ():Promise<string|false> => {
  // 获取设备
  const list: devicesType[] = devices();

  if (list.length === 0) {
    log("当前无设备连接，请连接后再执行该工具", "warn");
    return false;
  }

  const result = list.map((i) => ({ title: i.name, value: i.name }));

  const { value } = await prompts({
    type: "select",
    name: "value",
    message: "please select your device",
    choices: result,
  });
  currentDeviceName = value;
  return currentDeviceName;
};

const MIB = () => {
  // 获取配置文件
  const { backups, output } = getConfig();
  // 判断备份节点是否为空
  if (backups.length === 0) {
    log("当前备份节点为空", "warn");
    log("请在配置文件中添加备份节点", "warn");
  }
  if (backups.length > 0) {
    isPath(output);
    // 解析备份路径最后一个文件夹
    backups.forEach((item: SaveItemType) => {
      log(`当前执行备份任务:${item.comment}`);
      const arr = item.path.split("/").filter((i: string) => i !== "");
      const folderName = arr.at(-1);
      const backupDir = pathRepair(item.path);
      // 备份目录
      // 判断节点内是否有备份目录  // 拼接导出路径
      const rootPath = pathRepair(pathRepair(output) + folderName);
      const outputDir = item.output
        ? item.output && pathRepair(item.output)
        : rootPath;
      // 判断备份路径是否存在
      if (!isPathAdb(backupDir)) {
        log(`备份路径:${backupDir} 不存在已跳过`, "error");
      } else {
        // 判断导出路径
        isPath(outputDir);
        backup(backupDir, outputDir, item.full);
      }
    });
  }
  log("程序结束");
};


// 细化需要备份的文件，进入备份队列中
const backup = (target: string, output: string, full: boolean = false) => {
  if (!full) {
    // 备份非备份的文件数据
    // 获取手机中的文件信息,对比本地
    const { backupQueue } = initData(target, output);
    // 计算体积和数量
    computeBackupSize(backupQueue);
    // 执行备份程序
    move(backupQueue, output);
  } else {
    // 不文件对比，直接备份
    moveFolder(target, output);
  }
};


// 移动待备份文件队列中的文件
const move = (backupQueue: FileNodeType[], outputDir: string): void => {
  if (backupQueue.length === 0) {
    log("无需备份");
    return;
  }
  for (const fileN of backupQueue) {
    log(`正在备份${fileN.fileName}`);
    try {
      const out: string = execAdb(
        `pull "${fileN.filePath}" "${outputDir + fileN.fileName}"`,
      );
      const speed: string | null = out.match(speedReg) !== null ? out.match(speedReg)![0] : "读取速度失败";
      log(`平均传输速度${speed}`);
    } catch (e: any) {
      log(`备份${fileN.fileName}失败 error:${e.message}`, "error");
    }
  }
};
