class documentation

class EnvironHeaders(ImmutableHeadersMixin, Headers): (source)

Read only version of the headers from a WSGI environment. This provides the same interface as `Headers` and is constructed from a WSGI environment. From Werkzeug 0.3 onwards, the `KeyError` raised by this class is also a subclass of the :exc:`~exceptions.BadRequest` HTTP exception and will render a page for a ``400 BAD REQUEST`` if caught in a catch-all for HTTP exceptions.

Method	`__repr__`	Undocumented
Method	`__str__`	Returns formatted headers suitable for HTTP transmission.
Method	`clear`	Clears all headers.
Method	`get`	Return the default value if the requested data doesn't exist. If `type` is provided and is a callable it should convert the value, return it or raise a :exc:`ValueError` if that is not possible. In this case the function will return the default as if the value was not found:...
Method	`get_all`	Return a list of all the values for the named field.
Method	`getlist`	Return the list of items for a given key. If that key is not in the :class:`Headers`, the return value will be an empty list. Just like :meth:`get`, :meth:`getlist` accepts a `type` parameter. All items will be converted with the callable defined there.

Method	`to_wsgi_list`	Convert the headers into a list suitable for WSGI.
