        once.

        Use :meth:`get_data` to get the full data as bytes or text. The :attr:`data`
        attribute will contain the full bytes only if they do not represent form data.
        The :attr:`form` attribute will contain the parsed form data in that case.

        Unlike :attr:`input_stream`, this stream guards against infinite streams or
        reading past :attr:`content_length` or :attr:`max_content_length`.

        If ``max_content_length`` is set, it can be enforced on streams if
        ``wsgi.input_terminated`` is set. Otherwise, an empty stream is returned.

        If the limit is reached before the underlying stream is exhausted (such as a
        file that is too large, or an infinite stream), the remaining contents of the
        stream cannot be read safely. Depending on how the server handles this, clients
        may show a "connection reset" failure instead of seeing the 413 response.

        .. versionchanged:: 2.3
            Check ``max_content_length`` preemptively and while reading.

        .. versionchanged:: 0.9
            The stream is always set (but may be consumed) even if form parsing was
            accessed first.
