Base response class. The most important fact about a response object
is that it's a regular WSGI application. It's initialized with a couple
of response parameters (headers, body, status code etc.) and will start a
valid WSGI response when called with the environ and start response
callable.
Because it's a WSGI application itself processing usually ends before the
actual response is sent to the server. This helps debugging systems
because they can catch all the exceptions before responses are started.
Here a small example WSGI application that takes advantage of the
response objects::
from werkzeug.wrappers import BaseResponse as Response
def index():
return Response('Index page')
def application(environ, start_response):
path = environ.get('PATH_INFO') or '/'
if path == '/':
response = index()
else:
response = Response('Not Found', status=404)
return response(environ, start_response)
Like :class:`BaseRequest` which object is lacking a lot of functionality
implemented in mixins. This gives you a better control about the actual
API of your response objects, so you can create subclasses and add custom
functionality. A full featured response object is available as
:class:`Response` which implements a couple of useful mixins.
To enforce a new type of already existing responses you can use the
:meth:`force_type` method. This is useful if you're working with different
subclasses of response objects and you want to post process them with a
known interface.
Per default the response object will assume all the text data is `utf-8`
encoded. Please refer to :doc:`the unicode chapter </unicode>` for more
details about customizing the behavior.
Response can be any kind of iterable or string. If it's a string it's
considered being an iterable with one item which is the string passed.
Headers can be a list of tuples or a
:class:`~werkzeug.datastructures.Headers` object.
Special note for `mimetype` and `content_type`: For most mime types
`mimetype` and `content_type` work the same, the difference affects
only 'text' mimetypes. If the mimetype passed with `mimetype` is a
mimetype starting with `text/`, the charset parameter of the response
object is appended to it. In contrast the `content_type` parameter is
always added as header unmodified.
.. versionchanged:: 0.5
the `direct_passthrough` parameter was added.
:param response: a string or response iterable.
:param status: a string with a status or an integer with the status code.
:param headers: a list of headers or a
:class:`~werkzeug.datastructures.Headers` object.
:param mimetype: the mimetype for the response. See notice above.
:param content_type: the content type for the response. See notice above.
:param direct_passthrough: if set to `True` :meth:`iter_encoded` is not
called before iteration which makes it
possible to pass special iterators through
unchanged (see :func:`wrap_file` for more
details.)

type. Werkzeug will use the :class:`BaseResponse` internally in many
situations like the exceptions. If you call :meth:`get_response` on an
exception you will get back a regular :class:`BaseResponse` object, even
if you are using a custom subclass.
This method can enforce a given response type, and it will also
convert arbitrary WSGI callables into response objects if an environ
is provided::
# convert a Werkzeug response object into an instance of the
# MyResponseClass subclass.
response = MyResponseClass.force_type(response)
# convert any WSGI application into a response object
response = MyResponseClass.force_type(response, environ)
This is especially useful if you want to post-process responses in
the main dispatcher and use functionality provided by your subclass.
Keep in mind that this will modify response objects in place if
possible!
