Google 驱动 API 使用 Python 下载文件
Google Drive API downloading files with Python
我正在尝试制作一个程序来下载存储在 Google 驱动器中的文件,我已经在很多地方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 我得到这个程序:
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。
不知道哪里出错了

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。但是我的Google驱动器文件还没有下载
以下以 'file_id=....' 开头的行从左侧缩进 2 个空格。但是上面的代码缩进了 4 个空格。如果这些代码行要在 'main' 函数中,它们需要像其余代码一样缩进...一次 4 个空格。
这是复制和粘贴代码时的常见错误。如果您打算进一步扩展代码,请修改复制的代码以匹配或更改您的样式以适应。请注意 PyCharm 和 VSCode 等开发环境具有配置默认缩进的设置。
