写nodejs代码，遍历文件夹和子文件夹，如果rar或者zip,7z类的压缩包，需要解压密码，就删掉压缩包

好的，以下是可以用于遍历文件夹和子文件夹，检查并解压缩压缩文件的Node.js代码：

const fs = require('fs');
const path = require('path');
const unzipper = require('unzipper');
const Seven = require('node-7z');

const rootFolder = 'your/root/folder/path';
const password = 'your-password';

fs.readdir(rootFolder, (err, files) => {
  if (err) throw err;

  files.forEach(file => {
    const fileFullPath = path.join(rootFolder, file);

    fs.stat(fileFullPath, (err, stats) => {
      if (err) throw err;

      if (stats.isDirectory()) {
        // 如果是文件夹，递归遍历子文件夹
        recurseFolder(fileFullPath);
      } else {
        // 如果是文件，检查是否为压缩文件
        const ext = path.extname(file);
        if (['.zip', '.rar', '.7z'].includes(ext)) {
          console.log(`Found compressed file: ${file}`);

          // 解压缩文件
          const outputFolder = path.dirname(fileFullPath);
          const unzip = ext === '.7z' ?
            new Seven().extractFull(fileFullPath, outputFolder, { $: password }) :
            fs.createReadStream(fileFullPath).pipe(unzipper.Extract({ path: outputFolder }));

          // 监听解压缩事件
          unzip.on('error', err => {
            console.error(`Failed to extract ${file}: ${err}`);
          });
          unzip.on('close', () => {
            console.log(`Extracted ${file} successfully`);
            // 删除压缩文件
            fs.unlink(fileFullPath, err => {
              if (err) console.error(`Failed to delete ${file}: ${err}`);
              else console.log(`Deleted ${file}`);
            });
          });
        }
      }
    });
  });
});

function recurseFolder(folderPath) {
  fs.readdir(folderPath, (err, files) => {
    if (err) throw err;

    files.forEach(file => {
      const fileFullPath = path.join(folderPath, file);

      fs.stat(fileFullPath, (err, stats) => {
        if (err) throw err;

        if (stats.isDirectory()) {
          // 如果是文件夹，递归遍历子文件夹
          recurseFolder(fileFullPath);
        } else {
          // 如果是文件，检查是否为压缩文件
          const ext = path.extname(file);
          if (['.zip', '.rar', '.7z'].includes(ext)) {
            console.log(`Found compressed file: ${file}`);

            // 解压缩文件
            const outputFolder = path.dirname(fileFullPath);
            const unzip = ext === '.7z' ?
              new Seven().extractFull(fileFullPath, outputFolder, { $: password }) :
              fs.createReadStream(fileFullPath).pipe(unzipper.Extract({ path: outputFolder }));

            // 监听解压缩事件
            unzip.on('error', err => {
              console.error(`Failed to extract ${file}: ${err}`);
            });
            unzip.on('close', () => {
              console.log(`Extracted ${file} successfully`);
              // 删除压缩文件
              fs.unlink(fileFullPath, err => {
                if (err) console.error(`Failed to delete ${file}: ${err}`);
                else console.log(`Deleted ${file}`);
              });
            });
          }
        }
      });
    });
  });
}

该代码使用了Node.js自带的fs模块来遍历文件夹和子文件夹，并使用了第三方库unzipper来解压缩zip文件，使用了第三方库node-7z来解压缩rar和7z文件。在解压缩文件时，如果需要密码，可以将密码作为参数传递给node-7z库的extractFull()方法。解压缩后，代码会删除原始的压缩文件。
