I am creating a backup script for my GDrive folder. Every run I need to confirm to Google that the script can access GDrive. However, after the first run the verification code should be saved. In this post they mention a solution with a web server(Fulfilling Google Drive API OAuth2.0 Procedure w/o needing to find a verification code) - but I am looking for a solution for a simple backup script without a web server.
OAuth2WebServerFlow
to retrieve correct credentials with an existing verification code? Is there a way to skip step1_get_authorize_url()
? Or should I use oauth2
directly for this purpose?My Code
flow = OAuth2WebServerFlow(self.CLIENT_ID, self.CLIENT_SECRET, OAUTH_SCOPE, REDIRECT_URI, offline=True)
authorize_url = flow.step1_get_authorize_url()
print 'Go to the following link in your browser: ' + authorize_url
print
code = raw_input('Enter verification code: ').strip()
credentials = flow.step2_exchange(code)
http = httplib2.Http()
http = credentials.authorize(http)
drive_service = build('drive', 'v2', http=http)
Is this a command line tool? If so, try the following which will persist the credentials after prompting you the first time:
import httplib2
from oauth2client.file import Storage
from oauth2client.client import flow_from_clientsecrets
from oauth2client.tools import run
from apiclient.discovery import build
storage = Storage("saved_user_creds.dat")
credentials = storage.get()
if credentials is None or credentials.invalid:
credentials = run(flow_from_clientsecrets("client_secrets2.json", scope=["https://www.googleapis.com/auth/drive"]), storage)
http = credentials.authorize(httplib2.Http())
service = build("drive", "v2", http)
print service.files().list().execute()
