Gspread & Oauth2 on Python 3.4 - Oauth does not su

Question

I want to use gspread and since client authentication is outdated, I'm trying with Oauth2. I'm new to both gspread & Oauth2.

Piecing together from this basic Oauth2 example and the gspread documentation I have the most basic login function.

import gspread
from oauth2client.client import OAuth2WebServerFlow
CLIENT_ID = 'my id'
CLIENT_SECRET = 'my secret key'
flow = OAuth2WebServerFlow(client_id= CLIENT_ID,
    client_secret= CLIENT_SECRET,
    scope='https://docs.google.com/spreadsheets/',
    redirect_uri='http://localhost:80')
gc = gspread.authorize(flow)

The problem is that I get this error.

TypeError: 'OAuth2WebServerFlow' object does not support indexing

from the larger

C:\Python34\lib\site-packages\gspread\client.py:73: Warning: ClientLogin is deprecated: https://developers.google.com/identity/protocols/AuthForInstalledApps?csw=1

        Authorization with email and password will stop working on April 20, 2015.

        Please use oAuth2 authorization instead:
        http://gspread.readthedocs.org/en/latest/oauth2.html

""", Warning) Traceback (most recent call last): File "C:\Users\family\Desktop\mygspread.py", line 13, in gc = gspread.authorize(flow) File "C:\Python34\lib\site-packages\gspread\client.py", line 335, in authorize client.login() File "C:\Python34\lib\site-packages\gspread\client.py", line 105, in login data = {'Email': self.auth[0], TypeError: 'OAuth2WebServerFlow' object does not support indexing

Since both are official scripts - one from google and the other from burnash, I'm not sure what to change. I know the question is basic, but how do I log in with Python 3.4?

Answer 1

You can use OAUTH 2.0 using 2 ways.

1. Service account

Calls Google API's on behalf of your application instead of an end user

Follow here for more details:

import json
import gspread
from oauth2client.client import SignedJwtAssertionCredentials

json_key = json.load(open('gspread-april-2cd … ba4.json'))
scope = ['https://spreadsheets.google.com/feeds']

credentials = SignedJwtAssertionCredentials(json_key['client_email'], json_key['private_key'], scope)

gc = gspread.authorize(credentials)

wks = gc.open("Where is the money Lebowski?").sheet1

2. Web application

Accessed by web browsers over the network

Follow this blog for more details

import requests, gspread
from oauth2client.client import SignedJwtAssertionCredentials

def authenticate_google_docs():
    f = file(os.path.join('your-key-file.p12'), 'rb')
    SIGNED_KEY = f.read()
    f.close()
    scope = ['https://spreadsheets.google.com/feeds', 'https://docs.google.com/feeds']
    credentials = SignedJwtAssertionCredentials('[e-mail]', SIGNED_KEY, scope)

    data = {
        'refresh_token' : '<refresh-token-copied>',
        'client_id' : '<client-id-copied>',
        'client_secret' : '<client-secret-copied>',
        'grant_type' : 'refresh_token',
    }

    r = requests.post('https://accounts.google.com/o/oauth2/token', data = data)
    credentials.access_token = ast.literal_eval(r.text)['access_token']

    gc = gspread.authorize(credentials)
    return gc

Answer 2

I've figured it out. If anyone else is interested, this is what I needed to do

import json
import gspread
from oauth2client.client import SignedJwtAssertionCredentials
json_key = json.load(open('Gspread-762ec21ac2c5.json'))
scope = ['https://spreadsheets.google.com/feeds']
credentials = SignedJwtAssertionCredentials(json_key['client_email']
    , bytes(json_key['private_key']
    , 'utf-8')
    , scope)
gc = gspread.authorize(credentials)
wks = gc.open("mytestfile").sheet1
