Usage Example ------------- .. code-block:: python from werkzeug.wrappers.request import Request from werkzeug.exceptions import HTTPException, NotFound def view(request): raise NotFound() @Request.application def application(request): try: return view(request) except HTTPException as e: return e As you can see from this example those exceptions are callable WSGI applications. However, they are not Werkzeug response objects. You can get a response object by calling ``get_response()`` on a HTTP exception. Keep in mind that you may have to pass an environ (WSGI) or scope (ASGI) to ``get_response()`` because some errors fetch additional information relating to the request. If you want to hook in a different exception page to say, a 404 status code, you can add a second except for a specific subclass of an error: .. code-block:: python @Request.application def application(request): try: return view(request) except NotFound as e: return not_found(request) except HTTPException as e: return e ) annotationsN)datetime)escape)Markup) _get_environ) StartResponse)WSGIEnvironmentWWWAuthenticateResponse)RequestceZdZUdZdZded<dZded< d dfd ZeddZ d dd Z d dd Z d dd Z d dd Z dd ZddZddZxZS) HTTPExceptiona#The base class for all HTTP exceptions. This exception can be called as a WSGI application to render a default error page or you can catch the subclasses of it independently and render nicer error messages. .. versionchanged:: 2.1 Removed the ``wrap`` class method.

Since the client is already gone at that point attempting to send the error message to the client might not work and might ultimately result in another exception in the server. Mainly this is here so that it is silenced by default as far as Werkzeug is concerned. Since disconnections cannot be reliably detected and are unspecified by WSGI to a large extent this might or might not be raised if a client is gone. .. versionadded:: 0.8 NrDrOrPrQr0rrrhrhs rrhceZdZdZy) SecurityErrorzRaised if something triggers a security error.

The ``www_authenticate`` argument should be used to set the ``WWW-Authenticate`` header. This is used for HTTP basic auth and other schemes. Use :class:`~werkzeug.datastructures.WWWAuthenticate` to create correctly formatted values. Strictly speaking a 401 response is invalid if it doesn't provide at least one value for this header, although real clients typically don't care. :param description: Override the default message used for the body of the response. :param www-authenticate: A single value, or list of values, for the WWW-Authenticate header(s). .. versionchanged:: 2.0 Serialize multiple ``www_authenticate`` items into multiple ``WWW-Authenticate`` headers, rather than joining them into a single value, for better interoperability. .. versionchanged:: 0.15.3 If the ``www_authenticate`` argument is not set, the ``WWW-Authenticate`` header is not set. .. versionchanged:: 0.15.3 The ``response`` argument was restored. .. versionchanged:: 0.15.1 ``description`` was moved back as the first argument, restoring its previous position. .. versionchanged:: 0.15.0 ``www_authenticate`` was added as the first argument, ahead of ``description``. izThe server could not verify that you are authorized to access the URL requested.

By requiring each client to include a conditional header ("If-Match" or "If-Unmodified- Since") with the proper value retained from a recent GET request, the server ensures that each client has at least seen the previous revision of the resource. izZThis request is required to be conditional; try using "If-Match" or "If-Unmodified-Since".NrXr0rrrrrs  D 0rrcVeZdZdZ d dfd Z d dfd ZxZS) _RetryAfterzAdds an optional ``retry_after`` parameter which will set the ``Retry-After`` header.
