Google drive api python - 如何将文件夹或文件夹中的所有文件下载到特定的本地目标路径

Question

我需要下载驱动器文件夹或文件夹本身中的所有文件并将它们保存在特定的本地目的地，我的实际代码在这里：

import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request
import io
from googleapiclient.http import MediaIoBaseDownload

# If modifying these scopes, delete the file token.pickle.
SCOPES = ['https://www.googleapis.com/auth/drive.file','https://www.googleapis.com/auth/drive.folder']

def main():
    """Shows basic usage of the Drive v3 API.
    Prints the names and ids of the first 10 files the user has access to.
    """
    creds = None
    # The file token.pickle stores the user's access and refresh tokens, and is
    # created automatically when the authorization flow completes for the first
    # time.
    if os.path.exists('token.pickle'):
        with open('token.pickle', 'rb') as token:
            creds = pickle.load(token)
    # If there are no (valid) credentials available, let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                'credentials.json', SCOPES)
            creds = flow.run_local_server(port=0)
        # Save the credentials for the next run
        with open('token.pickle', 'wb') as token:
            pickle.dump(creds, token)

    service = build('drive', 'v3', credentials=creds)

    # Call the Drive v3 API
    
    file_id = '1qQ8hOSudoo7ISwqSAOeqsuBdsh-ZFCqm'
    request = service.files().get_media(fileId=file_id)
    fh = io.BytesIO()
    downloader = MediaIoBaseDownload(fh, request)
    done = False
    while done is False:
        status, done = downloader.next_chunk()
        print ("Download %d%%." % int(status.progress() * 100))

   

if __name__ == '__main__':
    main()

但它抛出以下错误，我也不知道如何设置特定的本地目的地

"HttpError: <HttpError 403 when requesting https://www.googleapis.com/drive/v3/files/1qQ8hOSudoo7ISwqSAOeqsuBdsh-ZFCqm?alt=media returned "Only files with binary content can be downloaded. Use Export with Docs Editors files.". Details: "Only files with binary content can be downloaded. Use Export with Docs Editors files.">"

Answer 1

执行file.list 将 parent 设置为您要查找的目录的文件 ID。

然后遍历返回的每个文件并使用您现在拥有的代码下载它。

  file_id = [File id from first call]
    request = service.files().get_media(fileId=file_id)
    fh = io.BytesIO()
    downloader = MediaIoBaseDownload(fh, request)
    done = False
    while done is False:
        status, done = downloader.next_chunk()
        print ("Download %d%%." % int(status.progress() * 100))

如果您正在寻找一种适合您的方法，您将找不到。您需要一次下载一个。
