如何从Firebase存储下载整个文件夹？

// 初始化 Firebase
const firebaseConfig = {
  apiKey: "YOUR_API_KEY",
  authDomain: "YOUR_PROJECT_ID.firebaseapp.com",
  projectId: "YOUR_PROJECT_ID",
  storageBucket: "YOUR_PROJECT_ID.appspot.com",
  messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
  appId: "YOUR_APP_ID"
};

firebase.initializeApp(firebaseConfig);

const storage = firebase.storage();
const folderRef = storage.ref().child('your_folder_name');

folderRef.listAll().then((result) => {
  result.items.forEach((itemRef) => {
    itemRef.getFile().then((file) => {
      console.log('File downloaded:', file.name);
      // 处理下载的文件
    }).catch((error) => {
      console.error('Error downloading file:', error);
    });
  });
}).catch((error) => {
  console.error('Error listing files:', error);
});

const admin = require('firebase-admin');
admin.initializeApp({
  credential: admin.credential.applicationDefault(),
  storageBucket: 'YOUR_PROJECT_ID.appspot.com'
});

const bucket = admin.storage().bucket();

async function downloadFolder(folderName) {
  const options = {
    prefix: folderName + '/'
  };

  const [files] = await bucket.getFiles(options);

  for (const file of files) {
    const destination = './downloads/' + file.name.split('/').pop();
    await bucket.file(file.name).download({ destination });
    console.log(`File ${file.name} downloaded to ${destination}`);
  }
}

downloadFolder('your_folder_name');
