import requests

google_bp = make_google_blueprint(
    client_id="foo",

)

@oauth_authorized.connect_via(google_bp)

Custom

Flask-Dance allows you to build authentication blueprints for any OAuth provider, not just the ones listed above. For example, let’s create a blueprint for a fictional OAuth provider called oauth-example.com. We check the documentation for oauth-example.com, and discover that they’re using OAuth 2, the access token URL is https://oauth-example.com/login/access_token, and the authorization URL is https://oauth-example.com/login/authorize. We could then build the blueprint like this:

from flask import Flask
from flask_dance.consumer import OAuth2ConsumerBlueprint

app = Flask(__name__)
example_blueprint = OAuth2ConsumerBlueprint(
    "oauth-example", __name__,
    client_id="my-key-here",
    client_secret="my-secret-here",
    base_url="https://oauth-example.com",
    token_url="https://oauth-example.com/login/access_token",
    authorization_url="https://oauth-example.com/login/authorize",
)
app.register_blueprint(example_blueprint, url_prefix="/login")

Now, in your page template, you can do something like:

<a href="{{ url_for("oauth-example.login") }}">Login with OAuth Example</a>

And in your views, you can make authenticated requests using the session attribute on the blueprint:

resp = example_blueprint.session.get("/user")
assert resp.ok
print("Here's the content of my response: " + resp.content)
