Isso diz ao Traefik para escutar na porta 9999 e usar outro arquivo `routes.toml`.

/// tip | "Dica"

Estamos usando a porta 9999 em vez da porta padrão HTTP 80 para que você não precise executá-lo com privilégios de administrador (`sudo`).

///

Agora crie esse outro arquivo `routes.toml`:

```TOML hl_lines="5  12  20"

			cw := &ConfigWriter{Stdout: gotOut}
			cd, _ := os.ReadFile(fmt.Sprintf("testdata/routes/%s/configdump.json", tt.name))

## Benutzerdefinierte `APIRoute`-Klasse in einem Router

Sie können auch den Parameter `route_class` eines `APIRouter` festlegen:

* `summary`: Eine kurze Zusammenfassung der API.
* `description`: Die Beschreibung Ihrer API. Dies kann Markdown enthalten und wird in der Dokumentation angezeigt.
* `routes`: Eine Liste von Routen, dies sind alle registrierten *Pfadoperationen*. Sie stammen von `app.routes`.

Der Parameter `summary` ist in OpenAPI 3.1.0 und höher verfügbar und wird von FastAPI 0.99.0 und höher unterstützt.
