如何导出特定google驱动器文件夹中的数据？

from google.oauth2.credentials import Credentials
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError
import io
from googleapiclient.http import MediaIoBaseDownload

def download_files_in_folder(folder_id, credentials):
    try:
        service = build('drive', 'v3', credentials=credentials)
        query = f"'{folder_id}' in parents"
        results = service.files().list(q=query, fields="nextPageToken, files(id, name)").execute()
        items = results.get('files', [])

        if not items:
            print('No files found.')
        else:
            print('Files:')
            for item in items:
                file_id = item['id']
                file_name = item['name']
                request = service.files().get_media(fileId=file_id)
                fh = io.BytesIO()
                downloader = MediaIoBaseDownload(fh, request)
                done = False
                print(f"Downloading {file_name}...")
                while done is False:
                    status, done = downloader.next_chunk()
                    print(f"Download {int(status.progress() * 100)}.")
                fh.seek(0)
                with open(file_name, 'wb') as f:
                    f.write(fh.read())
                print(f"{file_name} downloaded.")

    except HttpError as error:
        print(f'An error occurred: {error}')
        items = []

    return items

# 使用你的credentials和folder_id调用函数
credentials = Credentials.from_authorized_user_file('token.json', SCOPES)
folder_id = 'YOUR_FOLDER_ID'
download_files_in_folder(folder_id, credentials)
