This feature requires the third-party library `werkzeug`_: .. code-block:: console $ pip install werkzeug .. _werkzeug: https://werkzeug.palletsprojects.com/ :func:`route` accepts the same arguments as :func:`~websockets.sync.server.serve`, except as described below. The first argument is a :class:`werkzeug.routing.Map` that maps URL patterns to connection handlers. In addition to the connection, handlers receive parameters captured in the URL as keyword arguments. Here's an example:: from websockets.asyncio.router import route from werkzeug.routing import Map, Rule async def channel_handler(websocket, channel_id): ... url_map = Map([ Rule("/channel/", endpoint=channel_handler), ... ]) # set this future to exit the server stop = asyncio.get_running_loop().create_future() async with route(url_map, ...) as server: await stop Refer to the documentation of :mod:`werkzeug.routing` for details. If you define redirects with ``Rule(..., redirect_to=...)`` in the URL map, when the server runs behind a reverse proxy that modifies the ``Host`` header or terminates TLS, you need additional configuration: * Set ``server_name`` to the name of the server as seen by clients. When not provided, websockets uses the value of the ``Host`` header. * Set ``ssl=True`` to generate ``wss://`` URIs without actually enabling TLS. Under the hood, this bind the URL map with a ``url_scheme`` of ``wss://`` instead of ``ws://``. There is no need to specify ``websocket=True`` in each rule. It is added automatically. Args: url_map: Mapping of URL patterns to connection handlers. server_name: Name of the server as seen by clients. If :obj:`None`, websockets uses the value of the ``Host`` header. ssl: Configuration for enabling TLS on the connection. Set it to :obj:`True` if a reverse proxy terminates TLS connections. create_router: Factory for the :class:`Router` dispatching requests to handlers. Set it to a wrapper or a subclass to customize routing.
