js遍历文件夹

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

function traverseDirectory(dir, callback) {
  fs.readdirSync(dir).forEach(file => {
    const fullPath = path.join(dir, file);
    if (fs.lstatSync(fullPath).isDirectory()) {
      // 如果是文件夹，则递归遍历
      traverseDirectory(fullPath, callback);
    } else {
      // 如果是文件，则执行回调函数
      callback(fullPath);
    }
  });
}

// 使用示例
traverseDirectory('./your-directory-path', filePath => {
  console.log(filePath); // 打印文件路径
});

const fs = require('fs').promises;
const path = require('path');

async function traverseDirectoryAsync(dir, callback) {
  try {
    const files = await fs.readdir(dir);
    for (const file of files) {
      const fullPath = path.join(dir, file);
      const stat = await fs.lstat(fullPath);
      if (stat.isDirectory()) {
        await traverseDirectoryAsync(fullPath, callback);
      } else {
        callback(fullPath);
      }
    }
  } catch (err) {
    console.error(`Error accessing ${dir}: ${err}`);
  }
}

// 使用示例
traverseDirectoryAsync('./your-directory-path', filePath => {
  console.log(filePath); // 打印文件路径
});
