In vielen Fällen benötigt Ihre Anwendung möglicherweise einige externe Einstellungen oder Konfigurationen, zum Beispiel geheime Schlüssel, Datenbank-Anmeldeinformationen, Anmeldeinformationen für E-Mail-Dienste, usw.

Die meisten dieser Einstellungen sind variabel (können sich ändern), wie z. B. Datenbank-URLs. Und vieles könnten schützenswerte, geheime Daten sein.

/// tip

The *path operation* for `swagger_ui_redirect` is a helper for when you use OAuth2.

If you integrate your API with an OAuth2 provider, you will be able to authenticate and come back to the API docs with the acquired credentials. And interact with it using the real OAuth2 authentication.

Swagger UI will handle it behind the scenes for you, but it needs this "redirect" helper.
