L'une des principales fonctionnalités nécessaires aux systèmes API est la "<abbr title="également appelée
marshalling, conversion">sérialisation</abbr>" des données, qui consiste à prendre les données du code (Python) et à
les convertir en quelque chose qui peut être envoyé sur le réseau. Par exemple, convertir un objet contenant des
données provenant d'une base de données en un objet JSON. Convertir des objets `datetime` en strings, etc.

     * @param dstIndex the starting offset in the buffer
     * @param unicode true to use Unicode encoding, false for OEM encoding
     * @return the number of bytes written
     */
    protected int writeString(final String str, final byte[] dst, int dstIndex, final boolean unicode) {
        final int start = dstIndex;
        if (unicode) {
            // Unicode requires word alignment

Hug inspired **FastAPI** to declare a `response` parameter in functions to set headers and cookies.

Right before deciding to build **FastAPI** I found **APIStar** server. It had almost everything I was looking for and had a great design.

		if rec.Code != testCase.expectedRespStatus {
			t.Errorf("Test %d: %s: Expected the response status to be `%d`, but instead found `%d`", i+1, instanceType, testCase.expectedRespStatus, rec.Code)
		}
		// When the operation is successful, check if sending metadata is successful too
		if rec.Code == http.StatusNoContent {

    private String getId(final String sessionId, final String url) {
        final String id = sessionId + ID_SEPARATOR + new String(Base64.getUrlEncoder().withoutPadding().encode(url.getBytes(UTF_8)), UTF_8);
        if (id.length() <= idPrefixLength) {
            return id;
        }
        return id.substring(0, idPrefixLength) + MessageDigestUtil.digest("SHA-256", id.substring(idPrefixLength));

# JSON Compatible Encoder { #json-compatible-encoder }

There are some cases where you might need to convert a data type (like a Pydantic model) to something compatible with JSON (like a `dict`, `list`, etc).

For example, if you need to store it in a database.

For that, **FastAPI** provides a `jsonable_encoder()` function.

## Using the `jsonable_encoder` { #using-the-jsonable-encoder }

Hug inspirierte **FastAPI** dazu, einen `response`-Parameter in Funktionen zu deklarieren, um Header und Cookies zu setzen.

Kurz bevor ich mich entschied, **FastAPI** zu erstellen, fand ich den **APIStar**-Server. Er hatte fast alles, was ich suchte, und ein tolles Design.

Hug inspiró a **FastAPI** a declarar un parámetro `response` en funciones para configurar headers y cookies.

Justo antes de decidir construir **FastAPI** encontré **APIStar** server. Tenía casi todo lo que estaba buscando y tenía un gran diseño.

Hug inspirou **FastAPI** a declarar um parâmetro de `response` em funções para definir cabeçalhos e cookies.
