Syntax terms

socket Socket object
string string
number number is an op code indicating the type of web socket frame. Numbers 0-7 are non-control frames. Numbers 8-15 are control frames. Control frames are always sent immediately and cannot be fragmented. Specifying a reserved code will cause immediate request cancellation.
0 A continuation frame. A continuation frame is treated as text or binary based on the op code of the first frame. A continuation frame cannot also be the first frame.
1 A text frame. Text frames are are translated to ASCII with the translate table in effect for the port.
2 A binary frame. No translation is done for binary frames.
3-7 Reserved for future use and will cause request cancellation.
8 Connection close frame.
9 Ping. The receiver should respond with a Pong frame, unless a close frame has been received.
10 Pong. This is sent as a response to a Ping frame.
11-15 Reserved for future use and will cause request cancellation.
128 This value is added to the frame op code to indicate the final fragment of a non-control message. The first fragment may also be the final fragment.
boolean Boolean value that indicates whether to mask the data with a masking key. The default is not to mask the data. Masking is done using an internally generated masking key.

Usage notes


The following example sends a text message to the WebSocket client.

... %sock = WebSocket if %sock is null then audittext Socket closed, status is {$STATUSD} stop end if %op = %sock:ReceiveWebSocket(%wsi) if %op eq 1 then setText %wso = Received your text message of {%wsi:length} bytes. %sock:SendWebSocket(%wso, %op, true) end if ...
