Subclass [EventListener](https://square.github.io/okhttp/3.x/okhttp/okhttp3/EventListener.html) and override methods for the events you are interested in. In a successful HTTP call with no redirects or retries the sequence of events is described by this flow.

The most common is the implicit flow.

The most secure is the code flow, but is more complex to implement as it requires more steps. As it is more complex, many providers end up suggesting the implicit flow.

!!! note
    It's common that each authentication provider names their flows in a different way, to make it part of their brand.

	// StatelessHandler is handlers for one to many requests,
	// where responses may be dropped.
	// Stateless requests provide no incoming stream and there is no flow control
	// on outgoing messages.
	StatelessHandler struct {
		Handle StatelessHandlerFn
		// OutCapacity is the output capacity on the caller.
		// If <= 0 capacity will be 1.
		OutCapacity int

[Istio](https://istio.io/latest/docs/concepts/what-is-istio/) is an open platform for providing a uniform way to [integrate

and aggregate telemetry data. Istio's control plane provides an abstraction

## `username` und `password` entgegennehmen

Wir werden **FastAPIs** Sicherheits-Werkzeuge verwenden, um den `username` und das `password` entgegenzunehmen.

OAuth2 spezifiziert, dass der Client/Benutzer bei Verwendung des „Password Flow“ (den wir verwenden) die Felder `username` und `password` als Formulardaten senden muss.
