d S )!Ú JSONProvideraÉ A standard set of JSON operations for an application. 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 <flask.Flask.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.

library. Serializes the following additional data types:
|
|
- :class:`datetime.datetime` and :class:`datetime.date` are
|
serialized to :rfc:`822` strings. This is the same as the HTTP

date format.
|
- :class:`uuid.UUID` is serialized to a string.
|
- :class:`dataclasses.dataclass` is passed to

:func:`dataclasses.asdict`.
|
- :class:`~markupsafe.Markup` (or any object with a ``__html__``
|
method) will call the ``__html__`` method to get a string.
