This is documentation for the next version of K6. For the latest stable release, go to the latest version.
Socket.send(data)
Note
A module with a better and standard API exists.
The new k6/experimental/websockets API partially implements the WebSockets API living standard.
When possible, we recommend using the new API. It uses a global event loop for consistency with other k6 APIs and better performance.
Send a data string through the connection.
You can use JSON.stringify
to convert a JSON or JavaScript values to a JSON string.
Parameter | Type | Description |
---|---|---|
data | string | The data to send. |
Example
import ws from 'k6/ws';
export default function () {
const url = 'ws://echo.websocket.org';
const response = ws.connect(url, null, function (socket) {
socket.on('open', function () {
socket.send('my-message');
socket.send(JSON.stringify({ data: 'hola' }));
});
});
}
