Method addVerbHandlers

micro/service.go:656–666

addVerbHandlers generates control handlers for a specific verb. Each request generates 3 subscriptions, one for the general verb affecting all services written with the framework, one that handles all services of a particular kind, and finally a specific service instance.

(nc *nats.Conn, verb Verb, handler HandlerFunc)

// affecting all services written with the framework, one that handles
// all services of a particular kind, and finally a specific service instance.
func (svc *service) addVerbHandlers(nc *nats.Conn, verb Verb, handler HandlerFunc) error {

	if err := svc.addInternalHandler(nc, verb, "", "", name, handler); err != nil {
		return err
	}
	name = fmt.Sprintf("%s-kind", verb.String())
	if err := svc.addInternalHandler(nc, verb, svc.Config.Name, "", name, handler); err != nil {
		return err
	}
	return svc.addInternalHandler(nc, verb, svc.Config.Name, svc.id, verb.String(), handler)
}

// addInternalHandler registers a control subject handler.
