Si vous savez déjà ce que sont les « variables d'environnement » et comment les utiliser, vous pouvez passer cette section.

///

Une variable d'environnement (également appelée « env var ») est une variable qui vit en dehors du code Python, dans le système d'exploitation, et qui peut être lue par votre code Python (ou par d'autres programmes également).

## Ejecuta el Programa del Servidor { #run-the-server-program }

Si instalaste un servidor ASGI manualmente, normalmente necesitarías pasar una cadena de import en un formato especial para que importe tu aplicación FastAPI:

<div class="termy">

```console
$ uvicorn main:app --host 0.0.0.0 --port 80

    firstException = expected;
    // Second time should also fail, with a cached causal chain.
    expected = assertThrows(PotentialDeadlockException.class, () -> lockA.lock());
    checkMessage(expected, "LockB -> LockA", "LockA -> LockB");
    // The causal chain should be cached.
    assertThat(expected.getCause()).isEqualTo(firstException.getCause());

    firstException = expected;
    // Second time should also fail, with a cached causal chain.
    expected = assertThrows(PotentialDeadlockException.class, () -> lockA.lock());
    checkMessage(expected, "LockB -> LockA", "LockA -> LockB");
    // The causal chain should be cached.
    assertThat(expected.getCause()).isEqualTo(firstException.getCause());

Pero para esos responses adicionales tienes que asegurarte de devolver un `Response` como `JSONResponse` directamente, con tu código de estado y contenido.

## Response Adicional con `model` { #additional-response-with-model }

Puedes pasar a tus *decoradores de path operation* un parámetro `responses`.

Recibe un `dict`: las claves son los códigos de estado para cada response (como `200`), y los valores son otros `dict`s con la información para cada uno de ellos.

if NOT "%FESS_HEAP_SIZE%" == "" (
set FESS_MIN_MEM=%FESS_HEAP_SIZE%
set FESS_MAX_MEM=%FESS_HEAP_SIZE%
)

REM min and max heap sizes should be set to the same value to avoid
REM stop-the-world GC pauses during resize, and so that we can lock the
REM heap in memory on startup to prevent any of it from being swapped
REM out.

Mais **FastAPI** saura qu'il doit d'abord résoudre `query_extractor`, pour passer ses résultats à `query_or_cookie_extractor` lors de son appel.
