Das kann insbesondere eine gute Alternative zur Logik in einer Middleware sein.

Wenn Sie beispielsweise den Requestbody lesen oder manipulieren möchten, bevor er von Ihrer Anwendung verarbeitet wird.

!!! danger "Gefahr"
    Dies ist eine „fortgeschrittene“ Funktion.

    Wenn Sie gerade erst mit **FastAPI** beginnen, möchten Sie diesen Abschnitt vielleicht überspringen.

## Anwendungsfälle

Einige Anwendungsfälle sind:

	filter := filter.NewDiscoveryNamespacesFilter(namespaces, mesh, c.stop)
	kube.SetObjectFilter(c.Client, filter)

	syncers := make([]ComponentConstraint, 0, len(handlers))
	for _, h := range handlers {
		switch action {
		case Add:
			syncers = append(syncers, h.clusterAdded(c))
		case Update:
			syncers = append(syncers, h.clusterUpdated(c))
		}
	}
	if !c.Client.RunAndWait(c.stop) {
		log.Warnf("remote cluster %s failed to sync", c.ID)

	return true
}

type multiSyncer struct {
	syncers []Syncer
}

func (c multiSyncer) WaitUntilSynced(stop <-chan struct{}) bool {
	for _, s := range c.syncers {
		if !s.WaitUntilSynced(stop) {
			return false
		}
	}
	return true
}

func (c multiSyncer) HasSynced() bool {
	for _, s := range c.syncers {
		if !s.HasSynced() {
			return false
		}
	}
	return true

		diag.NewMessageType(diag.Warning, "C1", "Collapse danger: %v"),
		diag.MockResource("GrandCastle"),
		"the castle is too old",
	)

	msgs := diag.Messages{firstMsg, secondMsg}
	output, _ := Print(msgs, LogFormat, false)

	g.Expect(output).To(Equal(
		"Error [B1] (SoapBubble) Explosion accident: the bubble is too big\n" +
			"Warning [C1] (GrandCastle) Collapse danger: the castle is too old",
	))
