[英]How to download a file from Google Drive using Python and the Drive API v3
我曾尝试使用 python 脚本将文件从 Google Drive 下载到我的本地系统,但在运行 Python 脚本时面临“禁止”问题。 脚本如下:
import requests
url = "https://www.googleapis.com/drive/v3/files/1wPxpQwvEEOu9whmVVJA9PzGPM2XvZvhj?alt=media&export=download"
querystring = {"alt":"media","export":"download"}
headers = {
'Authorization': "Bearer TOKEN",
'Host': "www.googleapis.com",
'Accept-Encoding': "gzip, deflate",
'Connection': "keep-alive",
}
response = requests.request("GET", url, headers=headers, params=querystring)
print(response.url)
#
import wget
import os
from os.path import expanduser
myhome = expanduser("/home/sunarcgautam/Music")
### set working dir
os.chdir(myhome)
url = "https://www.googleapis.com/drive/v3/files/1wPxpQwvEEOu9whmVVJA9PzGPM2XvZvhj?alt=media&export=download"
print('downloading ...')
wget.download(response.url)
在这个脚本中,我遇到了禁止问题。 我在脚本中做错了什么吗?
我还尝试了在 Google Developer 页面上找到的另一个脚本,如下所示:
import auth
import httplib2
SCOPES = "https://www.googleapis.com/auth/drive.scripts"
CLIENT_SECRET_FILE = "client_secret.json"
APPLICATION_NAME = "test_Download"
authInst = auth.auth(SCOPES, CLIENT_SECRET_FILE, APPLICATION_NAME)
credentials = authInst.getCredentials()
http = credentials.authorize(httplib2.Http())
drive_serivce = discovery.build('drive', 'v3', http=http)
file_id = '1Af6vN0uXj8_qgqac6f23QSAiKYCTu9cA'
request = drive_serivce.files().export_media(fileId=file_id,
mimeType='application/pdf')
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))
这个脚本给了我一个URL mismatch error 。
那么应该为 Google 控制台凭据中的重定向 URL 提供什么? 或该问题的任何其他解决方案? 我是否必须在这两个脚本中从 Google 授权我的 Google 控制台应用程序? 如果是这样,授权应用程序的过程将是什么,因为我还没有找到任何关于它的文件。
要向 Google API 发出请求,工作流程本质上如下:
Drive API v3 的 Files 资源的可用方法在这里。
使用 Python Google APIs Client 时,您可以根据 Google APIs Client for Python 文档使用export_media()
或get_media()
此外,请检查您使用的范围,实际上允许您做您想做的事情(从用户的驱动器下载文件)并相应地设置它。 ATM 您的目标范围不正确。 请参阅OAuth 2.0 API 范围
