Isso não acontecerá se você importar esse módulo (arquivo).

Então, se você tiver outro arquivo `importer.py` com:

```Python
from myapp import app

# Mais um pouco de código
```

nesse caso, a variável `__name__` criada automaticamente dentro de `myapp.py` não terá o valor `"__main__"`.

Então, a linha:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

não será executada.

   * {@inheritDoc}
   *
   * <p>All elements in the returned list must be {@link ListenableFuture} instances. The easiest
   * way to obtain a {@code List<ListenableFuture<T>>} from this method is an unchecked (but safe)
   * cast:
   *
   * <pre>
   *   {@code @SuppressWarnings("unchecked") // guaranteed by invokeAll contract}
   *   {@code List<ListenableFuture<T>> futures = (List) executor.invokeAll(tasks);}
   * </pre>
   *

Neste caso, você pode usar `dict`:

## Recapitulação { #recap }

Use vários modelos Pydantic e herde livremente para cada caso.

Estos son cualquier request `OPTIONS` con headers `Origin` y `Access-Control-Request-Method`.

En este caso, el middleware interceptará el request entrante y responderá con los headers CORS adecuados, y un response `200` o `400` con fines informativos.

### Requests simples { #simple-requests }

Cualquier request con un header `Origin`. En este caso, el middleware pasará el request a través de lo normal, pero incluirá los headers CORS adecuados en el response.

    return dstOff + array.length;
  }

  // The fake cast to E is safe because the creation methods only allow E's
  @Override
  @SuppressWarnings("unchecked")
  public E get(int index) {
    return (E) array[index];
  }

  @SuppressWarnings("unchecked")
  @Override
  public UnmodifiableListIterator<E> listIterator(int index) {
    // for performance
    // The fake cast to E is safe because the creation methods only allow E's

response model, FastAPI usará el `jsonable_encoder` explicado en [Codificador Compatible con JSON](../tutorial/encoder.md) y lo pondrá en un `JSONResponse`.

Si declaras un `response_class` con un media type JSON (`application/json`), como es el caso con `JSONResponse`, los datos que devuelvas se convertirán automáticamente (y serán filtrados) con cualquier `response_model` de Pydantic que hayas declarado en el *path operation decorator*. Pero los datos no se serializarán a bytes JSON con Pydantic,...

   *     wrap(String.class) == String.class
