【问题描述】:
我正在尝试制作一个下载存储在 Google Drive 中的文件的程序,我在很多地方都在寻找如何做到这一点,但我无法使我的程序正常工作。
这是我的代码:
from __future__ import print_function
import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request
# If modifying these scopes, delete the file token.pickle.
SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly']
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)
# file_id is an example
file_id = '0BwwA4oUTeiV1UVNwOHItT0xfa2M'
request = drive_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)
如果我运行程序,我会得到: file_id = '0BwwA4oUTeiV1UVNwOHItT0xfa2M' ^ IndentationError: unindent 不匹配任何外部缩进级别
我也尝试过 Pydrive,但它对我不起作用。
我不知道错误在哪里。
编辑
感谢@caldweln,我解决了这个错误,但现在又出现了另一个错误。当我运行程序时,CMD 没有显示任何错误。但我的 Google 云端硬盘文件尚未下载
【问题讨论】:
-
“不起作用”是什么意思?运行时是否出现异常?
-
file_id = '0BwwA4oUTeiV1UVNwOHItT0xfa2M' ^ IndentationError: unindent 不匹配任何外部缩进级别
