En esos casos, puedes usar el parámetro del decorador de path operation `response_model` en lugar del tipo de retorno.

Puedes usar el parámetro `response_model` en cualquiera de las *path operations*:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* etc.

### Создание *эндпоинтов* с помощью `APIRouter` { #path-operations-with-apirouter }

В дальнейшем используйте `APIRouter` для объявления *эндпоинтов*, точно также, как вы используете класс `FastAPI`:

 * read-write locks. Conceptually, lock striping is the technique of dividing a lock into many
 * <i>stripes</i>, increasing the granularity of a single lock and allowing independent operations
 * to lock different stripes and proceed concurrently, instead of creating contention for a single
 * lock.
 *
 * <p>The guarantee provided by this class is that equal keys lead to the same lock (or semaphore),

// NOTE: once a tenant is frozen either two things needs to
// happen before resuming normal operations.
//   - Server needs to be restarted 'mc admin service restart'
//   - 'freeze' should be set to 'false' for this call
//     to resume normal operations.
func (sys *NotificationSys) ServiceFreeze(ctx context.Context, freeze bool) []NotificationPeerErr {
	serviceSig := serviceUnFreeze

        @DisplayName("Should check if async")
        void testAsyncProperty() {
            assertFalse(testMessage.isAsync());
        }

    @DisplayName("Flag Operations Tests")
    class FlagOperationsTests {

        @Test

            assertEquals(0, testMessage.getFlags());

```JSON
{"item_id": 5, "q": "somequery"}
```

Vous venez de créer une API qui :

* Reçoit les requêtes HTTP pour les _chemins_ `/` et `/items/{item_id}`.
* Les deux _chemins_ acceptent des opérations `GET` (également connu sous le nom de _méthodes_ HTTP).
* Le _chemin_ `/items/{item_id}` a un  _<abbr title="en anglais : path parameter">paramètre</abbr>_ `item_id` qui doit être un `int`.

Y aún así, probablemente no querrías que la aplicación quede muerta porque hubo un error en un lugar, probablemente querrás que **siga ejecutándose** al menos para las *path operations* que no estén rotas.
