Web socket response

Sends a message back to the client connection that delivered the current message to a Web socket listener. The connection is taken from the WebSocketListener metadata, so place it in the branch that starts at the listener Output pin.

Pins

Pin	Kind	Types	Description
Input	input	Viaducta.Plugins.Http.Types.WebSocketMessage, Viaducta.Plugins.TextPlugin.Types.TextRecord	Message to send.
Continue	continue		Called after sending, with the same input record.

Configuration

None besides the common settings.

Behaviour

• TextRecord: Value is sent as a text message (empty when null).
• WebSocketMessage: ContentByte is sent if set, otherwise ContentString (UTF-8); MessageType 0 = text, 1 = binary. Its SessionId must be the session of the metadata, otherwise an error is raised.
• Missing WebSocketListener metadata (not in a listener branch) raises an error.
• If the client is gone, the connection is closed and nothing is sent; Continue is still called.

Notes

• When you reuse the received WebSocketMessage and change only ContentString, also set ContentByte to null, otherwise the original bytes are echoed.
• To send to a different client, use the listener's Input pin with that client's SessionId.

Example

Web socket listener → Script (TextRecord with reply text) → Web socket response
