    def request_context(self, environ: WSGIEnvironment) -> AppContext:
        """Create an :class:`.AppContext` with request information representing
        the given WSGI environment. A context is automatically pushed when
        handling each request. When the context is pushed, :data:`.request`,
        :data:`.session`, :data:`g:, and :data:`.current_app` become available.

        This method should not be used in your own code. Creating a valid WSGI
        environ is not trivial. Use :meth:`test_request_context` to correctly
        create a WSGI environ and request context instead.

        See :doc:`/appcontext`.

        :param environ: A WSGI environment.
