nodejs中文件夹的哈希

const fs = require('fs');
const crypto = require('crypto');

function calculateFolderHash(folderPath) {
  const hash = crypto.createHash('sha256');
  const files = fs.readdirSync(folderPath);

  files.forEach(file => {
    const filePath = `${folderPath}/${file}`;
    const stats = fs.statSync(filePath);

    if (stats.isFile()) {
      const data = fs.readFileSync(filePath);
      hash.update(data);
    } else if (stats.isDirectory()) {
      const subFolderHash = calculateFolderHash(filePath);
      hash.update(subFolderHash);
    }
  });

  return hash.digest('hex');
}

const folderPath = '/path/to/folder';
const folderHash = calculateFolderHash(folderPath);
console.log(`Folder Hash: ${folderHash}`);
