This class implements a fully compliant Socket.IO web server with support for websocket and long-polling transports. :param client_manager: The client manager instance that will manage the client list. When this is omitted, the client list is stored in an in-memory structure, so the use of multiple connected servers is not possible. :param logger: To enable logging set to ``True`` or pass a logger object to use. To disable logging set to ``False``. The default is ``False``. Note that fatal errors are logged even when ``logger`` is ``False``. :param serializer: The serialization method to use when transmitting packets. Valid values are ``'default'``, ``'pickle'``, ``'msgpack'`` and ``'cbor'``. Alternatively, a subclass of the :class:`Packet` class with custom implementations of the ``encode()`` and ``decode()`` methods can be provided. Client and server must use compatible serializers. :param json: An alternative json module to use for encoding and decoding packets. Custom json modules must have ``dumps`` and ``loads`` functions that are compatible with the standard library versions. :param async_handlers: If set to ``True``, event handlers for a client are executed in separate threads. To run handlers for a client synchronously, set to ``False``. The default is ``True``. :param always_connect: When set to ``False``, new connections are provisory until the connect handler returns something other than ``False``, at which point they are accepted. When set to ``True``, connections are immediately accepted, and then if the connect handler returns ``False`` a disconnect is issued. Set to ``True`` if you need to emit events from the connect handler and your client is confused when it receives events before the connection acceptance. In any other case use the default of ``False``. :param kwargs: Connection parameters for the underlying Engine.IO server. The Engine.IO configuration supports the following settings: :param async_mode: The asynchronous model to use. See the Deployment section in the documentation for a description of the available options. Valid async modes are ``'threading'``, ``'eventlet'``, ``'gevent'`` and ``'gevent_uwsgi'``. If this argument is not given, ``'eventlet'`` is tried first, then ``'gevent_uwsgi'``, then ``'gevent'``, and finally ``'threading'``. The first async mode that has all its dependencies installed is then one that is chosen. :param ping_interval: The interval in seconds at which the server pings the client. The default is 25 seconds. For advanced control, a two element tuple can be given, where the first number is the ping interval and the second is a grace period added by the server. :param ping_timeout: The time in seconds that the client waits for the server to respond before disconnecting. The default is 5 seconds. :param max_http_buffer_size: The maximum size of a message when using the polling transport. The default is 1,000,000 bytes. :param allow_upgrades: Whether to allow transport upgrades or not. The default is ``True``. :param http_compression: Whether to compress packages when using the polling transport. The default is ``True``. :param compression_threshold: Only compress messages when their byte size is greater than this value. The default is 1024 bytes. :param cookie: If set to a string, it is the name of the HTTP cookie the server sends back tot he client containing the client session id. If set to a dictionary, the ``'name'`` key contains the cookie name and other keys define cookie attributes, where the value of each attribute can be a string, a callable with no arguments, or a boolean. If set to ``None`` (the default), a cookie is not sent to the client. :param cors_allowed_origins: Origin or list of origins that are allowed to connect to this server. Only the same origin is allowed by default. Set this argument to ``'*'`` to allow all origins, or to ``[]`` to disable CORS handling. :param cors_credentials: Whether credentials (cookies, authentication) are allowed in requests to this server. The default is ``True``. :param monitor_clients: If set to ``True``, a background task will ensure inactive clients are closed. Set to ``False`` to disable the monitoring task (not recommended). The default is ``True``. :param engineio_logger: To enable Engine.IO logging set to ``True`` or pass a logger object to use. To disable logging set to ``False``. The default is ``False``. Note that fatal errors are logged even when ``engineio_logger`` is ``False``.

It can be any string. The event names ``'connect'``, ``'message'`` and ``'disconnect'`` are reserved and should not be used. :param handler: The function that should be invoked to handle the event. When this parameter is not given, the method acts as a decorator for the handler function. :param namespace: The Socket.IO namespace for the event. If this argument is omitted the handler is associated with the default namespace. Example usage:: # as a decorator: @socket_io.on('connect', namespace='/chat') def connect_handler(sid, environ): print('Connection request') if environ['REMOTE_ADDR'] in blacklisted: return False # reject # as a method: def message_handler(sid, msg): print('Received message: ', msg) eio.send(sid, 'response') socket_io.on('message', namespace='/chat', handler=message_handler) The handler function receives the ``sid`` (session ID) for the client as first argument. The ``'connect'`` event handler receives the WSGI environment as a second argument, and can return ``False`` to reject the connection. The ``'message'`` handler and handlers for custom event names receive the message payload as a second argument. Any values returned from a message handler will be passed to the client's acknowledgement callback function if it exists. The ``'disconnect'`` handler does not take a second argument. /cfjvrij<|j<|SN)r#)handlereventrr7s r< set_handlerzServer.on..set_handlers5 -+- i(.5DMM) $U +Nr>Nr)r7rHrGrrIs`` ` r<rz Server.ons*J$   ?

It can be any string. The event names ``'connect'``, ``'message'`` and ``'disconnect'`` are reserved and should not be used. :param data: The data to send to the client or clients. Data can be of type ``str``, ``bytes``, ``list`` or ``dict``. To send multiple arguments, use a tuple where each element is of one of the types indicated above. :param to: The recipient of the message. This can be set to the session ID of a client to address only that client, to any any custom room created by the application to address all the clients in that room, or to a list of custom room names. If this argument is omitted the event is broadcasted to all connected clients. :param room: Alias for the ``to`` parameter. :param skip_sid: The session ID of a client to skip when broadcasting to a room or to all clients. This can be used to prevent a message from being sent to the sender. To skip multiple sids, pass a list. :param namespace: The Socket.IO namespace for the event. If this argument is omitted the event is emitted to the default namespace. :param callback: If given, this function will be called to acknowledge the the client has received the message. The arguments that will be passed to the function are those provided by the client. Callback functions can only be used when addressing an individual client. :param ignore_queue: Only used when a message queue is configured. If set to ``True``, the event is emitted to the clients directly, without going through the queue. This is more efficient, but only works when a single server process is used. It is recommended to always leave this parameter with its default value of ``False``. Note: this method is not thread safe. If multiple threads are emitting at the same time to the same client, then messages composed of multiple packets may end up being sent in an incorrect sequence. Use standard concurrency solutions (such as a Lock object) to prevent this situation. rDzemitting event "%s" to %s [%s]all)roomskip_sidcallbackN)r infor2emit) r7rHdatatorXrYrrZr:s r<r\z Server.emitsiX$ zT 95  3 %y Jt#+h JBH Jr>c 6|jd||||||d|y)a Send a message to one or more connected clients.
