WebSocketServer
===============

**Inherits:** :ref:`WebSocketMultiplayerPeer<class_WebSocketMultiplayerPeer>` **<** :ref:`NetworkedMultiplayerPeer<class_NetworkedMultiplayerPeer>` **<** :ref:`PacketPeer<class_PacketPeer>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`

A WebSocket server implementation.

Description
-----------

This class implements a WebSocket server that can also support the high-level multiplayer API.

After starting the server (:ref:`listen<class_WebSocketServer_method_listen>`), you will need to :ref:`NetworkedMultiplayerPeer.poll<class_NetworkedMultiplayerPeer_method_poll>` it at regular intervals (e.g. inside :ref:`Node._process<class_Node_method__process>`). When clients connect, disconnect, or send data, you will receive the appropriate signal.

**Note:** Not available in HTML5 exports.

Signals
-------

.. _class_WebSocketServer_signal_client_close_request:

- **client_close_request** **(** :ref:`int<class_int>` id, :ref:`int<class_int>` code, :ref:`String<class_String>` reason **)**

Emitted when a client requests a clean close. You should keep polling until you get a :ref:`client_disconnected<class_WebSocketServer_signal_client_disconnected>` signal with the same ``id`` to achieve the clean close. See :ref:`WebSocketPeer.close<class_WebSocketPeer_method_close>` for more details.

----

.. _class_WebSocketServer_signal_client_connected:

- **client_connected** **(** :ref:`int<class_int>` id, :ref:`String<class_String>` protocol **)**

Emitted when a new client connects. "protocol" will be the sub-protocol agreed with the client.

----

.. _class_WebSocketServer_signal_client_disconnected:

- **client_disconnected** **(** :ref:`int<class_int>` id, :ref:`bool<class_bool>` was_clean_close **)**

Emitted when a client disconnects. ``was_clean_close`` will be ``true`` if the connection was shutdown cleanly.

----

.. _class_WebSocketServer_signal_data_received:

- **data_received** **(** :ref:`int<class_int>` id **)**

Emitted when a new message is received.

**Note:** This signal is *not* emitted when used as high-level multiplayer peer.

Property Descriptions
---------------------

.. _class_WebSocketServer_property_bind_ip:

- :ref:`String<class_String>` **bind_ip**

+-----------+--------------------+
| *Default* | ``"*"``            |
+-----------+--------------------+
| *Setter*  | set_bind_ip(value) |
+-----------+--------------------+
| *Getter*  | get_bind_ip()      |
+-----------+--------------------+

When not set to ``*`` will restrict incoming connections to the specified IP address. Setting ``bind_ip`` to ``127.0.0.1`` will cause the server to listen only to the local host.

----

.. _class_WebSocketServer_property_ca_chain:

- :ref:`X509Certificate<class_X509Certificate>` **ca_chain**

+----------+---------------------+
| *Setter* | set_ca_chain(value) |
+----------+---------------------+
| *Getter* | get_ca_chain()      |
+----------+---------------------+

When using SSL (see :ref:`private_key<class_WebSocketServer_property_private_key>` and :ref:`ssl_certificate<class_WebSocketServer_property_ssl_certificate>`), you can set this to a valid :ref:`X509Certificate<class_X509Certificate>` to be provided as additional CA chain information during the SSL handshake.

----

.. _class_WebSocketServer_property_handshake_timeout:

- :ref:`float<class_float>` **handshake_timeout**

+-----------+------------------------------+
| *Default* | ``3.0``                      |
+-----------+------------------------------+
| *Setter*  | set_handshake_timeout(value) |
+-----------+------------------------------+
| *Getter*  | get_handshake_timeout()      |
+-----------+------------------------------+

The time in seconds before a pending client (i.e. a client that has not yet finished the HTTP handshake) is considered stale and forcefully disconnected.

----

.. _class_WebSocketServer_property_private_key:

- :ref:`CryptoKey<class_CryptoKey>` **private_key**

+----------+------------------------+
| *Setter* | set_private_key(value) |
+----------+------------------------+
| *Getter* | get_private_key()      |
+----------+------------------------+

When set to a valid :ref:`CryptoKey<class_CryptoKey>` (along with :ref:`ssl_certificate<class_WebSocketServer_property_ssl_certificate>`) will cause the server to require SSL instead of regular TCP (i.e. the ``wss://`` protocol).

----

.. _class_WebSocketServer_property_ssl_certificate:

- :ref:`X509Certificate<class_X509Certificate>` **ssl_certificate**

+----------+----------------------------+
| *Setter* | set_ssl_certificate(value) |
+----------+----------------------------+
| *Getter* | get_ssl_certificate()      |
+----------+----------------------------+

When set to a valid :ref:`X509Certificate<class_X509Certificate>` (along with :ref:`private_key<class_WebSocketServer_property_private_key>`) will cause the server to require SSL instead of regular TCP (i.e. the ``wss://`` protocol).

Method Descriptions
-------------------

.. _class_WebSocketServer_method_disconnect_peer:

- void **disconnect_peer** **(** :ref:`int<class_int>` id, :ref:`int<class_int>` code=1000, :ref:`String<class_String>` reason="" **)**

Disconnects the peer identified by ``id`` from the server. See :ref:`WebSocketPeer.close<class_WebSocketPeer_method_close>` for more information.

----

.. _class_WebSocketServer_method_get_peer_address:

- :ref:`String<class_String>` **get_peer_address** **(** :ref:`int<class_int>` id **)** |const|

Returns the IP address of the given peer.

----

.. _class_WebSocketServer_method_get_peer_port:

- :ref:`int<class_int>` **get_peer_port** **(** :ref:`int<class_int>` id **)** |const|

Returns the remote port of the given peer.

----

.. _class_WebSocketServer_method_has_peer:

- :ref:`bool<class_bool>` **has_peer** **(** :ref:`int<class_int>` id **)** |const|

Returns ``true`` if a peer with the given ID is connected.

----

.. _class_WebSocketServer_method_is_listening:

- :ref:`bool<class_bool>` **is_listening** **(** **)** |const|

Returns ``true`` if the server is actively listening on a port.

----

.. _class_WebSocketServer_method_listen:

- :ref:`Error<enum_@GlobalScope_Error>` **listen** **(** :ref:`int<class_int>` port, :ref:`PoolStringArray<class_PoolStringArray>` protocols=PoolStringArray(  ), :ref:`bool<class_bool>` gd_mp_api=false **)**

Starts listening on the given port.

You can specify the desired subprotocols via the "protocols" array. If the list empty (default), no sub-protocol will be requested.

If ``true`` is passed as ``gd_mp_api``, the server will behave like a network peer for the :ref:`MultiplayerAPI<class_MultiplayerAPI>`, connections from non-Godot clients will not work, and :ref:`data_received<class_WebSocketServer_signal_data_received>` will not be emitted.

If ``false`` is passed instead (default), you must call :ref:`PacketPeer<class_PacketPeer>` functions (``put_packet``, ``get_packet``, etc.), on the :ref:`WebSocketPeer<class_WebSocketPeer>` returned via ``get_peer(id)`` to communicate with the peer with given ``id`` (e.g. ``get_peer(id).get_available_packet_count``).

----

.. _class_WebSocketServer_method_stop:

- void **stop** **(** **)**

Stops the server and clear its state.
