Variables

read only code:Int

Returns an unsigned short containing the close code send by the server. The following values are permitted status codes.

Status code	Name	Description
0–999		Reserved and not used.
1000	CLOSE_NORMAL	Normal closure; the connection successfully completed whatever purpose for which it was created.
1001	CLOSE_GOING_AWAY	The endpoint is going away, either because of a server failure or because the browser is navigating away from the page that opened the connection.
1002	CLOSE_PROTOCOL_ERROR	The endpoint is terminating the connection due to a protocol error.
1003	CLOSE_UNSUPPORTED	The connection is being terminated because the endpoint received data of a type it cannot accept (for example, a text-only endpoint received binary data).
1004		Reserved. A meaning might be defined in the future.
1005	CLOSE_NO_STATUS	Reserved. Indicates that no status code was provided even though one was expected.
1006	CLOSE_ABNORMAL	Reserved. Used to indicate that a connection was closed abnormally (that is, with no close frame being sent) when a status code is expected.
1007	Unsupported Data	The endpoint is terminating the connection because a message was received that contained inconsistent data (e.g., non-UTF-8 data within a text message).
1008	Policy Violation	The endpoint is terminating the connection because it received a message that violates its policy. This is a generic status code, used when codes 1003 and 1009 are not suitable.
1009	CLOSE_TOO_LARGE	The endpoint is terminating the connection because a data frame was received that is too large.
1010	Missing Extension	The client is terminating the connection because it expected the server to negotiate one or more extension, but the server didn't.
1011	Internal Error	The server is terminating the connection because it encountered an unexpected condition that prevented it from fulfilling the request.
1012	Service Restart	The server is terminating the connection because it is restarting. [Ref]
1013	Try Again Later	The server is terminating the connection due to a temporary condition, e.g. it is overloaded and is casting off some of its clients. [Ref]
1014		Reserved for future use by the WebSocket standard.
1015	TLS Handshake	Reserved. Indicates that the connection was closed due to a failure to perform a TLS handshake (e.g., the server certificate can't be verified).
1016–1999		Reserved for future use by the WebSocket standard.
2000–2999		Reserved for use by WebSocket extensions.
3000–3999		Available for use by libraries and frameworks. May not be used by applications. Available for registration at the IANA via first-come, first-serve.
4000–4999		Available for use by applications.
