The /whisk.system/websocket package offers a convenient way post messages to a WebSocket.
The package includes the following action:
| Entity | Type | Parameters | Description |
|---|---|---|---|
/whisk.system/websocket | package | uri | Utilities for communicating with WebSockets |
/whisk.system/websocket/send | 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 send action.
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
