API
Flower API enables to manage the cluster via REST API, call tasks and receive task events in real-time via WebSockets.
For example you can restart worker’s pool by:
$ curl -X POST http://localhost:5555/api/worker/pool/restart/myworker
Or call a task by:
$ curl -X POST -d '{"args":[1,2]}' http://localhost:5555/api/task/async-apply/tasks.add
Or terminate executing task by:
$ curl -X POST -d 'terminate=True' http://localhost:5555/api/task/revoke/8a4da87b-e12b-4547-b89a-e92e4d1f8efd
Or receive task completion events in real-time:
var ws = new WebSocket("ws://localhost:5555/api/task/events/task-succeeded/");
ws.onmessage = function (event) {
console.log(event.data);
}
