Always a byte string. :term:`Bytes-like objects ` and native strings containing only ascii characters will be automatically converted to byte strings. .. attribute:: target The target of an HTTP request, e.g. ``b"/index.html"``, or one of the more exotic formats described in `RFC 7320, section 5.3 `_. Always a byte string. :term:`Bytes-like objects ` and native strings containing only ascii characters will be automatically converted to byte strings. .. attribute:: headers Request headers, represented as a list of (name, value) pairs.

Fields: .. attribute:: data A :term:`bytes-like object` containing part of a message body. Or, if using the ``combine=False`` argument to :meth:`Connection.send`, then any object that your socket writing code knows what to do with, and for which calling :func:`len` returns the number of bytes that will be written -- see :ref:`sendfile` for details. .. attribute:: chunk_start A marker that indicates whether this data object is from the start of a chunked transfer encoding chunk. This field is ignored when when a Data event is provided to :meth:`Connection.send`: it is only valid on events emitted from :meth:`Connection.next_event`. You probably shouldn't use this attribute at all; see :ref:`chunk-delimiters-are-bad` for details. .. attribute:: chunk_end A marker that indicates whether this data object is the last for a given chunked transfer encoding chunk.
