### Class

# Soup WebsocketConnection

#### Description [src]

    final class Soup.WebsocketConnection : GObject.Object {
      /* No available fields */
    }

The WebSocket Protocol

Provides support for the WebSocket protocol.

To connect to a WebSocket server, create a `SoupSession` and call `soup_session_websocket_connect_async()`. To accept WebSocket connections, create a `SoupServer` and add a handler to it with `soup_server_add_websocket_handler()`.

(Lower-level support is available via `soup_websocket_client_prepare_handshake()` and `soup_websocket_client_verify_handshake()`, for handling the client side of the WebSocket handshake, and `soup_websocket_server_process_handshake()` for handling the server side.)

`SoupWebsocketConnection` handles the details of WebSocket communication. You can use `soup_websocket_connection_send_text()` and `soup_websocket_connection_send_binary()` to send data, and the `SoupWebsocketConnection::message` signal to receive data. (`SoupWebsocketConnection` currently only supports asynchronous I/O.)

###### soup_websocket_connection_get_connection_type

Get the connection type (client/server) of the connection.

###### soup_websocket_connection_get_extensions

Get the extensions chosen via negotiation with the peer.

###### soup_websocket_connection_get_io_stream

Get the I/O stream the WebSocket is communicating over.

###### soup_websocket_connection_get_keepalive_interval

Gets the keepalive interval in seconds or 0 if disabled.

###### soup_websocket_connection_get_state

Get the current state of the WebSocket.

###### soup_websocket_connection_get_uri

Get the URI of the WebSocket.

###### soup_websocket_connection_send_binary

Send a binary message to the peer.

###### soup_websocket_connection_send_message

Send a message of the given `type` to the peer. Note that this method, allows to send text messages containing `NULL` characters.

###### soup_websocket_connection_send_text

Send a `NULL`-terminated text (UTF-8) message to the peer.

###### soup_websocket_connection_set_keepalive_interval

Sets the interval in seconds on when to send a ping message which will serve as a keepalive message.

###### soup_websocket_connection_set_max_incoming_payload_size

Sets the maximum payload size allowed for incoming packets.
