Flask-Micropub
A Flask extension to support IndieAuth and Micropub clients.
Authentication
Authentication uses the
IndieAuth flow to confirm a user
controls a particular URL, without requesting any sort of permissions
or access token. Annotate an endpoint with
@micropub.authenticated_handler
and then call
micropub.authenticate
to initiate the login.
Authorization
Authorization uses the full
Micropub flow to authenticate a
user and then request an access token with which to make micropub
requests. Annotate an endpoint with @micropub.authorized_handler
and
then call micropub.authorize
to initiate the login.
CSRF
MicropubClient provides a simple mechanism to deter Cross-Site Request Forgery. Based on this Flask snippet, we generate a random string, pass it to the indieauth service via the state parameter, and then confirm we get the same random string back later.
This helps prevent malicious sites from sending users to your indieauth endpoint against their will.
Example
from flask import Flask, request, url_for
from flask.ext.micropub import MicropubClient
app = Flask(__name__)
micropub = MicropubClient(app)
@app.route('/login')
def login():
return micropub.authorize(
me, scope=request.args.get('scope'))
@app.route('/micropub-callback')
@micropub.authorized_handler
def micropub_callback(resp):
print('success!', resp.me, resp.access_token, resp.next_url, resp.error)
