Flask-GoogleAuth 0.4.2

Super simple OpenID and Google Federated Auth for Flask apps.

This is a partial port of torando.auth to be used with Flask.

It is small, self contained and do not use any filesystem operations. Greate for internal apps.

Written by Alexander Saltanov, inspired by Kenneth Reitz.

Usage

Example usage for Google Federated Login.

Routes /login/ and /logout/ will be provided automagically.

Require an account from a given Google Apps domain for your Flask apps:

from flask import Flask, g
from flask_googleauth import GoogleFederated

# Setup Flask
app = Flask(__name__)
app.secret_key = "random secret key"

# Setup Google Federated Auth
auth = GoogleFederated("mokote.com", app)

@app.route("/")
@auth.required
def secret():
    # Once user is authenticated, his name and email are accessible as
    # g.user.name and g.user.email.
    return "You have rights to be here, %s (%s)" % (g.user.name, g.user.email)

app.run()

If you want to authenticate your users with general Google OpenID you should import and use GoogleAuth instead of GoogleFederated:

auth = GoogleAuth(app)

You can force all requests to be authenticated by setting force_auth_on_every_request on the auth object:

auth.force_auth_on_every_request = True

Install

To install Flask-GoogleAuth:

pip install flask-googleauth

Prerequisites

Be sure that your Google Apps domain is enabled to be an OpenID provider under “Advanced tools” → “Federated Login using OpenID”.
