使用NodeJS从Google Cloud Storage Bucket下载文件夹

npm init -y

npm install @google-cloud/storage

const { Storage } = require('@google-cloud/storage');
const fs = require('fs');
const path = require('path');

const storage = new Storage();

async function downloadFolder(bucketName, folderName, destinationPath) {
  const bucket = storage.bucket(bucketName);
  const [files] = await bucket.getFiles({ prefix: folderName });

  for (const file of files) {
    const filePath = file.name;
    const destFilePath = path.join(destinationPath, filePath);

    if (file.isDirectory()) {
      fs.mkdirSync(destFilePath, { recursive: true });
      await downloadFolder(bucketName, filePath, destFilePath);
    } else {
      await file.download({ destination: destFilePath });
    }
  }
}

const bucketName = 'your-bucket-name';
const folderName = 'your-folder-name';
const destinationPath = 'your-destination-path';

downloadFolder(bucketName, folderName, destinationPath)
  .then(() => {
    console.log('Folder downloaded successfully.');
  })
  .catch((error) => {
    console.error('Error downloading folder:', error);
  });
