You should only call this method if the transport method is `POST`, `PUT`, or `PATCH`. If the mimetype of the data transmitted is `multipart/form-data` the files multidict will be filled with `FileStorage` objects. If the mimetype is unknown the input stream is wrapped and returned as first argument, else the stream is empty. This is a shortcut for the common usage of :class:`FormDataParser`. Have a look at :ref:`dealing-with-request-data` for more details. .. versionadded:: 0.5 The `max_form_memory_size`, `max_content_length` and `cls` parameters were added. .. versionadded:: 0.5.1 The optional `silent` flag was added. :param environ: the WSGI environment to be used for parsing. :param stream_factory: An optional callable that returns a new read and writeable file descriptor. This callable works the same as :meth:`~BaseResponse._get_file_stream`. :param charset: The character set for URL and url encoded form data. :param errors: The encoding error behavior. :param max_form_memory_size: the maximum number of bytes to be accepted for in-memory stored form data. If the data exceeds the value specified an :exc:`~exceptions.RequestEntityTooLarge` exception is raised. :param max_content_length: If this is provided and the transmitted data is longer than this value an :exc:`~exceptions.RequestEntityTooLarge` exception is raised. :param cls: an optional dict class to use. If this is not specified or `None` the default :class:`MultiDict` is used. :param silent: If set to False parsing errors will not be caught. :return: A tuple in the form ``(stream, form, files)``.

By itself it can parse multipart and url encoded form data. It can be subclassed and extended but for most mimetypes it is a better idea to use the untouched stream and expose it as separate attributes on a request object. .. versionadded:: 0.8 :param stream_factory: An optional callable that returns a new read and writeable file descriptor.
