This one extends the default encoder by also supporting ``datetime``, ``UUID``, ``dataclasses``, and ``Markup`` objects. ``datetime`` objects are serialized as RFC 822 datetime strings. This is the same as the HTTP date format.

If there is an app context pushed, use the current app's configured encoder (:attr:`~flask.Flask.json_encoder`), or fall back to the default :class:`JSONEncoder`.

It accepts the same arguments and returns a JSON string. Note that this is available in templates through the ``|tojson`` filter which will also mark the result as safe. Due to how this function escapes certain characters this is safe even if used outside of ``<script>`` tags. The following characters are escaped in strings: - ``<`` - ``>`` - ``&`` - ``'`` This makes it safe to embed such strings in any place in HTML with the notable exception of double quoted attributes. In that case single quote your attributes or HTML escape it in addition. .. versionchanged:: 0.10 This function's return value is now always safe for HTML usage, even if outside of script tags or if used in XHTML. This rule does not hold true when using this function in HTML attributes that are double quoted. Always single quote attributes if you use the ``|tojson`` filter. Alternatively use ``|tojson|forceescape``. �<z\u003c�>z\u003e�&z\u0026�'z\u0027r r )r �replace� _slash_escape)rZ rB r[ r r r! r s ����� r c K s |� tt| fi |���� dS )z:Like :func:`htmlsafe_dumps` but writes into a file object.N)r$ r r )rZ r rB r r r! r - s r c O sr d}d}t jd st jr d}d}| r2|r2td��n t| �dkrH| d }n| pN|}t jt|||d �d t jd d �S ) a This function wraps :func:`dumps` to add a few enhancements that make life easier. It turns the JSON output into a :class:`~flask.Response` object with the :mimetype:`application/json` mimetype. For convenience, it also converts multiple arguments into an array or multiple keyword arguments into a dict. This means that both ``jsonify(1,2,3)`` and ``jsonify([1,2,3])`` serialize to ``[1,2,3]``. For clarity, the JSON serialization behavior has the following differences from :func:`dumps`: 1. Single argument: Passed straight through to :func:`dumps`. 2. Multiple arguments: Converted to an array before being passed to :func:`dumps`. 3. Multiple keyword arguments: Converted to a dict before being passed to :func:`dumps`. 4. Both args and kwargs: Behavior undefined and will throw an exception. Example usage:: from flask import jsonify @app.route('/_get_current_user') def get_current_user(): return jsonify(username=g.user.username, email=g.user.email, id=g.user.id) This will send a JSON response like this to the browser:: { "username": "admin", "email": "admin@localhost", "id": 42 } .. versionchanged:: 0.11 Added support for serializing top-level arrays. This introduces a security risk in ancient browsers. See :ref:`json-security` for details. This function's response will be pretty printed if the ``JSONIFY_PRETTYPRINT_REGULAR`` config parameter is set to True or the Flask app is running in debug mode. Compressed (not pretty) formatting currently means no indents and no spaces after separators. .. versionadded:: 0.2 N)�,�:ZJSONIFY_PRETTYPRINT_REGULARr )z, z: z=jsonify() behavior undefined when passed both args and kwargsrK r )�indent� separators� ZJSONIFY_MIMETYPE)�mimetype)r r@ �debugr% rR �response_classr )�argsrB rf rg rT r r r! r 2 s 1 �r c K s t t| fi |���S )N)r r )rZ rB r r r! � tojson_filterw s rm )N)N)N)N)N)N)&r8 rL r r* r r Z itsdangerousr r1 Zjinja2r Z werkzeug.httpr �_compatr r �globalsr r r- � ImportErrorr rc �__all__r" r& r r rE rF rV r r r r r r rm r r r r! �<module> sB * + %E
