UUUU139U UU UUU4S jjn[ UUT5 $ )a> 140Create a WebSocket server listening on ``host`` and ``port``.141 142Whenever a client connects, the server creates a :class:`ServerConnection`,143performs the opening handshake, and delegates to the ``handler``.144 145The handler receives the :class:`ServerConnection` instance, which you can146use to send and receive messages.147 148Once the handler completes, either normally or with an exception, the server149performs the closing handshake and closes the connection.150 151This function returns a :class:`Server` whose API mirrors152:class:`~socketserver.BaseServer`. Treat it as a context manager to ensure153that it will be closed and call :meth:`~Server.serve_forever` to serve154requests::155 156 from websockets.sync.server import serve157 158 def handler(websocket):159 ...160 161 with serve(handler, ...) as server:162 server.serve_forever()163 164Args:165 handler: Connection handler. It receives the WebSocket connection,166 which is a :class:`ServerConnection`, in argument.167 host: Network interfaces the server binds to.168 See :func:`~socket.create_server` for details.169 port: TCP port the server listens on.170 See :func:`~socket.create_server` for details.171 sock: Preexisting TCP socket. ``sock`` replaces ``host`` and ``port``.172 You may call :func:`socket.create_server` to create a suitable TCP173 socket.174 ssl: Configuration for enabling TLS on the connection.175 origins: Acceptable values of the ``Origin`` header, for defending176 against Cross-Site WebSocket Hijacking attacks. Values can be177 :class:`str` to test for an exact match or regular expressions178 compiled by :func:`re.compile` to test against a pattern. Include179 :obj:`None` in the list if the lack of an origin is acceptable.180 extensions: List of supported extensions, in order in which they181 should be negotiated and run.182 subprotocols: List of supported subprotocols, in order of decreasing183 preference.184 select_subprotocol: Callback for selecting a subprotocol among185 those supported by the client and the server. It receives a186 :class:`ServerConnection` (not a187 :class:`~websockets.server.ServerProtocol`!) instance and a list of188 subprotocols offered by the client. Other than the first argument,189 it has the same behavior as the190 :meth:`ServerProtocol.select_subprotocol191 <websockets.server.ServerProtocol.select_subprotocol>` method.192 compression: The "permessage-deflate" extension is enabled by default.193 Set ``compression`` to :obj:`None` to disable it. See the194 :doc:`compression guide <../../topics/compression>` for details.195 process_request: Intercept the request during the opening handshake.196 Return an HTTP response to force the response. Return :obj:`None` to197 continue normally. When you force an HTTP 101 Continue response, the198 handshake is successful. Else, the connection is aborted.199 process_response: Intercept the response during the opening handshake.200 Modify the response or return a new HTTP response to force the201 response. Return :obj:`None` to continue normally. When you force an202 HTTP 101 Continue response, the handshake is successful. Else, the203 connection is aborted.204 server_header: Value of the ``Server`` response header.205 It defaults to ``"Python/x.y.z websockets/X.Y"``. Setting it to206 :obj:`None` removes the header.207 open_timeout: Timeout for opening connections in seconds.208 :obj:`None` disables the timeout.209 ping_interval: Interval between keepalive pings in seconds.210 :obj:`None` disables keepalive.211 ping_timeout: Timeout for keepalive pings in seconds.212 :obj:`None` disables timeouts.213 close_timeout: Timeout for closing connections in seconds.214 :obj:`None` disables the timeout.215 max_size: Maximum size of incoming messages in bytes.216 :obj:`None` disables the limit. You may pass a ``(max_message_size,217 max_fragment_size)`` tuple to set different limits for messages and218 fragments when you expect long messages sent in short fragments.219 max_queue: High-water mark of the buffer where frames are received.220 It defaults to 16 frames. The low-water mark defaults to ``max_queue221 // 4``. You may pass a ``(high, low)`` tuple to set the high-water222 and low-water marks. If you want to disable flow control entirely,223 you may set it to ``None``, although that's a bad idea.224 logger: Logger for this server.225 It defaults to ``logging.getLogger("websockets.server")``. See the226 :doc:`logging guide <../../topics/logging>` for details.227 create_connection: Factory for the :class:`ServerConnection` managing228 the connection. Set it to a wrapper or a subclass to customize229 connection handling.230 231Any other keyword arguments are passed to :func:`~socket.create_server`.232 233N� ssl_contextz ssl_context was renamed to sslr� zunsupported compression: �unixF�pathzmissing path argument�familyz(path and sock arguments are incompatibleT)� server_side�do_handshake_on_connectc � >^� [ T
