谷歌驱动器api如何将文件夹内的所有文件或文件夹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，我的实际代码如下：

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()

但是它抛出了以下错误，我也不知道如何设置一个特定的本地目的地

"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

为您要查找的目录的文件id执行file.list设置父级。

然后循环浏览返回的每个文件，并使用现在的代码下载它。

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))

如果你正在寻找一种能为你做这件事的方法，你找不到。您需要一次下载一个。
