It has a dict-like interface, but is ordered, can store the same key multiple times, and iterating yields ``(key, value)`` pairs instead of only keys. This data structure is useful if you want a nicer way to handle WSGI headers which are stored as tuples in a list. From Werkzeug 0.3 onwards, the :exc:`KeyError` raised by this class is also a subclass of the :class:`~exceptions.BadRequest` HTTP exception and will render a page for a ``400 BAD REQUEST`` if caught in a catch-all for HTTP exceptions. Headers is mostly compatible with the Python :class:`wsgiref.headers.Headers` class, with the exception of `__getitem__`. :mod:`wsgiref` will return `None` for ``headers['missing']``, whereas :class:`Headers` will raise a :class:`KeyError`. To create a new ``Headers`` object, pass it a list, dict, or other ``Headers`` object with default values. These values are validated the same way values added later are. :param defaults: The list of default values for the :class:`Headers`. .. versionchanged:: 3.1 Implement ``|`` and ``|=`` operators. .. versionchanged:: 2.1.0 Default values are validated the same as values added later. .. versionchanged:: 0.9 This data structure now stores unicode values similar to how the multi dicts do it. The main difference is that bytes can be set as well which will automatically be latin1 decoded. .. versionchanged:: 0.9 The :meth:`linked` function was removed without replacement as it was an API that does not support the changes to the encoding model.
