/whisk.system/websocket package offers a convenient way post messages to a WebSocket.
The package includes the following action:
|package||uri||Utilities for communicating with WebSockets|
|action||uri, payload||Send the payload to the WebSocket URI|
If you plan to send many messages to the same WebSocket URI, creating a package binding with the
uri value is suggested. With binding, you don't need to specify the value each time that you use the
/whisk.system/websocket/send action will send a payload to a WebSocket URI. The parameters are as follows:
uri: The URI of the websocket server (e.g. ws://mywebsockethost:80)
payload: The message you wish to send to the WebSocket
