It supports iteration to receive messages:: for message in websocket: 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. Args: socket: Socket connected to a WebSocket server. protocol: Sans-I/O connection. close_timeout: Timeout for closing the connection in seconds.  close_timeoutc`|tj|_t||||y)Nr) threadingr response_rcvdsuper__init__)selfsocketprotocolr __class__s V/var/www/highfloat_scraper/venv/lib/python3.12/site-packages/websockets/sync/client.pyr%zClientConnection.__init__1s2 &__.

This function returns a :class:`ClientConnection` instance, which you can use to send and receive messages. :func:`connect` may be used as a context manager:: async with websockets.sync.client.connect(...) as websocket: ... The connection is closed automatically when exiting the context. Args: uri: URI of the WebSocket server. sock: Preexisting TCP socket. ``sock`` overrides the host and port from ``uri``. You may call :func:`socket.create_connection` to create a suitable TCP socket. ssl_context: Configuration for enabling TLS on the connection. server_hostname: Host name for the TLS handshake. ``server_hostname`` overrides the host name from ``uri``. origin: Value of the ``Origin`` header, for servers that require it. 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. additional_headers (HeadersLike | None): Arbitrary HTTP headers to add to the handshake request. user_agent_header: Value of the ``User-Agent`` request header. It defaults to ``"Python/x.y.z websockets/X.Y"``. Setting it to :obj:`None` removes the header. 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. open_timeout: Timeout for opening the connection in seconds. :obj:`None` disables the timeout. close_timeout: Timeout for closing the connection in seconds. :obj:`None` disables the timeout. max_size: Maximum size of incoming messages in bytes. :obj:`None` disables the limit. logger: Logger for this client. It defaults to ``logging.getLogger("websockets.client")``. See the :doc:`logging guide <../../topics/logging>` for details. create_connection: Factory for the :class:`ClientConnection` managing the connection. Set it to a wrapper or a subclass to customize connection handling. Raises: InvalidURI: If ``uri`` isn't a valid WebSocket URI. OSError: If the TCP connection fails. InvalidHandshake: If the opening handshake fails. TimeoutError: If the opening handshake times out.
