It supports asynchronous iteration to receive messages:: async for message in websocket: await process(message) The iterator exits normally when the connection is closed with close code 1000 (OK) or 1001 (going away) or without a close code. It raises a :exc:`~websockets.exceptions.ConnectionClosedError` when the connection is closed with any other code.

Setting it to :obj:`None` removes the header. open_timeout: Timeout for opening connections in seconds. :obj:`None` disables the timeout. logger: Logger for this server.

Whenever a client connects, the server creates a :class:`ServerConnection`, performs the opening handshake, and delegates to the ``handler`` coroutine. The handler receives the :class:`ServerConnection` instance, which you can use to send and receive messages. Once the handler completes, either normally or with an exception, the server performs the closing handshake and closes the connection. This coroutine returns a :class:`Server` whose API mirrors :class:`asyncio.Server`. Treat it as an asynchronous context manager to ensure that the server will be closed:: from websockets.asyncio.server import serve def handler(websocket): ... # set this future to exit the server stop = asyncio.get_running_loop().create_future() async with serve(handler, host, port): await stop Alternatively, call :meth:`~Server.serve_forever` to serve requests and cancel it to stop the server:: server = await serve(handler, host, port) await server.serve_forever() Args: handler: Connection handler. It receives the WebSocket connection, which is a :class:`ServerConnection`, in argument. host: Network interfaces the server binds to. See :meth:`~asyncio.loop.create_server` for details. port: TCP port the server listens on. See :meth:`~asyncio.loop.create_server` for details. origins: Acceptable values of the ``Origin`` header, for defending against Cross-Site WebSocket Hijacking attacks. Values can be :class:`str` to test for an exact match or regular expressions compiled by :func:`re.compile` to test against a pattern. Include :obj:`None` in the list if the lack of an origin is acceptable. extensions: List of supported extensions, in order in which they should be negotiated and run. subprotocols: List of supported subprotocols, in order of decreasing preference. select_subprotocol: Callback for selecting a subprotocol among those supported by the client and the server. It receives a :class:`ServerConnection` (not a :class:`~websockets.server.ServerProtocol`!) instance and a list of subprotocols offered by the client. Other than the first argument, it has the same behavior as the :meth:`ServerProtocol.select_subprotocol ` method. compression: The "permessage-deflate" extension is enabled by default. Set ``compression`` to :obj:`None` to disable it. See the :doc:`compression guide <../../topics/compression>` for details. process_request: Intercept the request during the opening handshake. Return an HTTP response to force the response or :obj:`None` to continue normally. When you force an HTTP 101 Continue response, the handshake is successful. Else, the connection is aborted. ``process_request`` may be a function or a coroutine. process_response: Intercept the response during the opening handshake. Return an HTTP response to force the response or :obj:`None` to continue normally. When you force an HTTP 101 Continue response, the handshake is successful. Else, the connection is aborted. ``process_response`` may be a function or a coroutine. server_header: Value of the ``Server`` response header. It defaults to ``"Python/x.y.z websockets/X.Y"``. Setting it to :obj:`None` removes the header. open_timeout: Timeout for opening connections in seconds. :obj:`None` disables the timeout. ping_interval: Interval between keepalive pings in seconds. :obj:`None` disables keepalive. ping_timeout: Timeout for keepalive pings in seconds. :obj:`None` disables timeouts. close_timeout: Timeout for closing connections in seconds. :obj:`None` disables the timeout. max_size: Maximum size of incoming messages in bytes. :obj:`None` disables the limit. max_queue: High-water mark of the buffer where frames are received. It defaults to 16 frames. The low-water mark defaults to ``max_queue // 4``. You may pass a ``(high, low)`` tuple to set the high-water and low-water marks. If you want to disable flow control entirely, you may set it to ``None``, although that's a bad idea. write_limit: High-water mark of write buffer in bytes. It is passed to :meth:`~asyncio.WriteTransport.set_write_buffer_limits`. It defaults to 32 KiB. You may pass a ``(high, low)`` tuple to set the high-water and low-water marks. logger: Logger for this server. It defaults to ``logging.getLogger("websockets.server")``. See the :doc:`logging guide <../../topics/logging>` for details. create_connection: Factory for the :class:`ServerConnection` managing the connection. Set it to a wrapper or a subclass to customize connection handling. Any other keyword arguments are passed to the event loop's :meth:`~asyncio.loop.create_server` method. For example: * You can set ``ssl`` to a :class:`~ssl.SSLContext` to enable TLS. * You can set ``sock`` to provide a preexisting TCP socket. You may call :func:`socket.create_server` (not to be confused with the event loop's :meth:`~asyncio.loop.create_server` method) to create a suitable server socket and customize it. * You can set ``start_serving`` to ``False`` to start accepting connections only after you call :meth:`~Server.start_serving()` or :meth:`~Server.serve_forever()`.
