Subclasses of this can be used to customize JSON behavior or use different JSON libraries. To implement a provider for a specific library, subclass this base class and implement at least :meth:`dumps` and :meth:`loads`. All other methods have default implementations. To use a different provider, either subclass ``Flask`` and set :attr:`~flask.Flask.json_provider_class` to a provider class, or set :attr:`app.json ` to an instance of the class. :param app: An application instance. This will be stored as a :class:`weakref.proxy` on the :attr:`_app` attribute. .. versionadded:: 2.2 apprreturnNonecCst||_dS)N)weakrefproxy_app)selfr rU/var/www/html/ecg_monitoring/venv/lib/python3.10/site-packages/flask/json/provider.py__init__&szJSONProvider.__init__objt.AnykwargsstrcKt)zSerialize data as JSON. :param obj: The data to serialize. :param kwargs: May be passed to the underlying JSON library.
