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.
