Pour ces cas, vous pouvez spécifier un appel à `jsonable_encoder` pour convertir vos données avant de les passer à une réponse :

{* ../../docs_src/response_directly/tutorial001.py hl[6:7,21:22] *}

/// note | Détails techniques

Vous pouvez aussi utiliser `from starlette.responses import JSONResponse`.

    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.
    assertSame(firstException.getCause(), expected.getCause());
    // lockA should work after lockB is released.

## 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

import okhttp3.internal.UTC

/** The last four-digit year: "Fri, 31 Dec 9999 23:59:59 GMT". */
internal const val MAX_DATE = 253402300799999L

/**
 * Most websites serve cookies in the blessed format. Eagerly create the parser to ensure such
 * cookies are on the fast path.

private val STANDARD_DATE_FORMAT =
  object : ThreadLocal<DateFormat>() {
    override fun initialValue(): DateFormat {

import (
	"fmt"

	"github.com/golang-jwt/jwt/v4"

var (

En nuestro ejemplo de código arriba, no lo usamos directamente, pero se lo pasamos a FastAPI para que lo use.

El parámetro `lifespan` de la app de `FastAPI` toma un **async context manager**, por lo que podemos pasar nuestro nuevo `lifespan` async context manager a él.

<div class="termy">

```console
$ pip install "hypercorn[trio]"

### Exécuter avec Trio

Ensuite, vous pouvez passer l'option de ligne de commande `--worker-class` avec la valeur `trio` :

<div class="termy">

```console
$ hypercorn main:app --worker-class trio
```

</div>
