Strategies
Just like in Passport, strategies implement authentication via a specific provider. To create your own strategy, you need to implement the
AuthStrategy class.All strategies must implement
authenticate(req, res, [opts]).This method should only have three possible results.
Possibility #1: Return
trueThis signifies that whatever authentication process you performed was completed successfully, and that it did not produce any result that needs to be serialized.
Possibility #2: Return
falseThis represents an authentication failure, and will throw a
401 Not Authenticated error.Possibility #3: Return something else entirely
This signifies that although the user was successfully authenticated, the authenticated user needs to be serialized into another format for the entire authentication flow to be considered complete.
For example, you usually need to save a user's ID after authentication.
import 'package:angel3_auth/angel3_auth.dart';
class MyStrategy implements AuthStrategy {
@override
authenticate(req, res, [opts]) async {
final user =
await login(req.body['username'], req.body['password']);
return user != null ? user : false;
}
}
