ohawf 23.0.10

Easy Google login from Jupyter Notebooks

ohawf

Install

pip install -U ohawf

Are you trying to log into Google Analytics, Search Console, or even Google Photos from a Jupyter Notebook? Does all the advice telling you to register as a developer and the mangled Google examples have you frustrated? Well then, ohawf is for you.

How to use

import ohawf

creds = ohawf.get()

Why So Easy?

Google OAuth2 woes go away once you can use the authentication scheme that pops up the same “login as Google” web-prompt that all Mobile and Web apps seem to be using these days. It doesn’t seem possible, but this authentication scheme actually works from a Jupyter Notebook in JupyterLab.

Ohawf makes JupyterLab behave like an installed app, so that when you first run creds= ohawf.get(), you’ll be presented with the “Login with Google” prompt. Just just wait a moment, it will pop up a window separate from JupyterLab’s own, and let you log in then prompt you to close the window. If not, Drink Me.

A Tale of 2 Installed App Flows

What makes ohawf work is this line:

from google_auth_oauthlib.flow import InstalledAppFlow

The Old Way: Copy/Paste Token

InstalledAppFlow’s run_console() prompts you to copy/paste a token from a browser tab to Jupyter and used to work well, but that approach has been deprecated. It can still be forced to work, but it’s not so easy.

The New Way: Gotta Have a Webserver

The new way which is now the ohawf default is run_local_server(). This is what you encounter all the time with mobile apps when you see “Login with Google”. An embedded browser pops up, goes through login, then returns you to the mobile app. This works in Jupyter too. If you have problems, run Jupyter this way. And if you need to force ohawf to use run_console() for a server installation, you can do this:

import ohawf
creds = ohawf.get(cli=True)

But then you’ll have to whitelist your email address, and you can only do that through the Google Cloud Console so chicken-and-egg. If you have to go that route, consider just registering as a Google developer and downloading a OAuth Client secret json file like this:

• Go to https://console.cloud.google.com
• Make sure you’re in the correct Google account.
• Create a new Project.
• Go to API & Services.
• Enable the APIs & Services you want to use.
• Go to Credentials.
• Create a new OAuth 2.0 Client IDs of the Desktop App type.
• Go to OAuth consent screen and set it up.
• Go to +Add users, under test users (gets around tight security)
• Add the users for the test (your gmail, necessary even though already the app owner)
• Go back to Credentials and download OAuth Client.
  • Typically, client_secret_[secret].apps.googleusercontent.com.json
• Use that file with ohawf

Once you have the Client Secret JSON file, you can call ohawf like this:

import ohawf

creds = ohawf.get(file="client_secret.json")

Adding Scopes

The ohawf package uses the following default scopes if you don’t set any:

https://www.googleapis.com/auth/spreadsheets
https://www.googleapis.com/auth/gmail.modify
https://www.googleapis.com/auth/userinfo.email
https://www.googleapis.com/auth/youtube.readonly
https://www.googleapis.com/auth/analytics.readonly
https://www.googleapis.com/auth/webmasters.readonly
https://www.googleapis.com/auth/yt-analytics.readonly
https://www.googleapis.com/auth/photoslibrary.readonly

If you want to set your own scopes, create a Python list of scopes and feed it to ohawf:

scopes = ["https://www.googleapis.com/auth/spreadsheets"]
creds = ohawf(scopes=scopes)

Google Services

from apiclient.discovery import build

Connect to Google services by giving build any (activated) API name, version and credentials such listing your GSC sites:

gsc_service = build('searchconsole', 'v1', credentials=cred)
gsc_sites = gsc_service.sites().list().execute()
[print(x['siteUrl']) for x in gsc_sites['siteEntry']];

…or this go list your GA accounts:

ga_service = build('analytics', 'v3', credentials=cred)
ga_accounts = ga_service.management().accounts().list().execute()
[print((x['id'], x['name'])) for x in ga_accounts['items']];
