How to add url parameters to flask-dance "redirect_to" variable?

I am using the flask-dance library to handle custom OAuth, here's a code sample:

oh = OAuth2ConsumerBlueprint(
    "oh", __name__,
    client_id="",
    client_secret="",
    authorization_url="",
    token_url="",
    redirect_uri="",
    scope=[""],
    redirect_to='/oauth-redirect'
)

I want to specify a URL parameter so that when the token is granted and the 3rd party website redirects back to my website, it knows where it came from. Like:

localhost:5010/oauth-redirect?id=oh

I know the redirect_to variable is a repurposed url_for via:

https://flask-dance.readthedocs.io/en/latest/api.html#flask_dance.consumer.OAuth2ConsumerBlueprint

which accepts vars like: url_for('page.route', foo="bar") but how do I do something similar, be it passing data to the page or as a url parameter?

Solution

  • You can hook into the oauth_authorized signal, and return a response object. This response can redirect to whatever URL you want, and you can pass whatever data you want in the URL parameters.
