3. El dataclass `Author` incluye una lista de dataclasses `Item`.

4. El dataclass `Author` se usa como el parámetro `response_model`.

5. Puedes usar otras anotaciones de tipos estándar con dataclasses como el request body.

    En este caso, es una lista de dataclasses `Item`.

6. Aquí estamos regresando un diccionario que contiene `items`, que es una lista de dataclasses.

### <a href="https://requests.readthedocs.io" class="external-link" target="_blank">Requests</a> { #requests }

**FastAPI** na verdade não é uma alternativa ao **Requests**. O escopo deles é muito diferente.

Na verdade, é comum utilizar Requests dentro de uma aplicação FastAPI.

Ainda assim, o FastAPI tirou bastante inspiração do Requests.

Notice that the *path operations* define the models they use for request payload and response payload, using the models `Item` and `ResponseMessage`.

### API Docs { #api-docs }

If you go to `/docs`, you will see that it has the **schemas** for the data to be sent in requests and received in responses:

<img src="/img/tutorial/generate-clients/image01.png">

    public DefaultLifecycleBindingsInjector(LifeCyclePluginAnalyzer lifecycle) {
        this.lifecycle = lifecycle;
    }

    @Override
    public void injectLifecycleBindings(Model model, ModelBuildingRequest request, ModelProblemCollector problems) {
        String packaging = model.getPackaging();

        Collection<Plugin> defaultPlugins = lifecycle.getPluginsBoundByDefaultToAllLifecycles(packaging);

)

// getLocalServerProperty - returns madmin.ServerProperties for only the
// local endpoints from given list of endpoints
func getLocalServerProperty(endpointServerPools EndpointServerPools, r *http.Request, metrics bool) madmin.ServerProperties {
	addr := globalLocalNodeName
	if r != nil {
		addr = r.Host
	}
	if globalIsDistErasure {
		addr = globalLocalNodeName
	}
	poolNumbers := make(map[int]struct{})

	server = httptest.NewUnstartedServer(handler)
	server.Config.Addr = listener.Addr().String()
	server.Listener = listener
	server.Start()
	return server
}

func dummyRequestValidate(r *http.Request) error {
	return nil
}

func dummyTokenValidate(token string) error {
	if token == "debug" {
		return nil
	}
	return fmt.Errorf("invalid token. want empty, got %s", token)
}

)

const dummyRoleARN = "dummy-internal"

// ListAccessKeysOpenIDBulk - GET /minio/admin/v3/idp/openid/list-access-keys-bulk
func (a adminAPIHandlers) ListAccessKeysOpenIDBulk(w http.ResponseWriter, r *http.Request) {
	ctx := r.Context()

	// Get current object layer instance.
	objectAPI := newObjectLayerFn()
	if objectAPI == nil || globalNotificationSys == nil {

Das `@app.get("/")` sagt **FastAPI**, dass die Funktion direkt darunter für die Bearbeitung von <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Requests</abbr> zuständig ist, die an:

* den Pfad `/`
* unter der Verwendung der <abbr title="eine HTTP-GET-Methode"><code>get</code>-Operation</abbr> gehen

## Zusammenfassung { #recap }

Sie können mehrere Body-Parameter zu Ihrer *Pfadoperation-Funktion* hinzufügen, obwohl ein Request nur einen einzigen Body enthalten kann.

Aber **FastAPI** wird sich darum kümmern, Ihnen korrekte Daten in Ihrer Funktion zu überreichen, und das korrekte Schema in der *Pfadoperation* zu validieren und zu dokumentieren.
