Se você verificar a `/docs`, verá que o campo `data` espera bytes codificados em base64:

<div class="screenshot">
<img src="/img/tutorial/json-base64-bytes/image01.png">
</div>

Você poderia enviar uma request assim:

```json
{

    }
  }

  @Test
  fun testBuildIfSupported() {
    val actual = OpenJSSEPlatform.buildIfSupported()
    assertThat(actual).isNotNull()
  }

  private fun enableTls() {
    // Generate a self-signed cert for the server to serve and the client to trust.
    // can't use TlsUtil.localhost with a non OpenJSSE trust manager
    val heldCertificate =
      HeldCertificate
        .Builder()
        .commonName("localhost")

I'll tell you a bit more about these **concepts** here, and that would hopefully give you the **intuition** you would need to decide how to deploy your API in very different environments, possibly even in **future** ones that don't exist yet.

By considering these concepts, you will be able to **evaluate and design** the best way to deploy **your own APIs**.

- L'utilisateur saisit le `username` et le `password` dans le frontend, puis appuie sur Entrée.
- Le frontend (exécuté dans le navigateur de l'utilisateur) envoie ce `username` et ce `password` vers une URL spécifique de notre API (déclarée avec `tokenUrl="token"`).
- L'API vérifie ce `username` et ce `password`, et répond avec un « token » (nous n'avons encore rien implémenté de tout cela).

Bunu çok basitleştiren birçok paket, veri modeli, veritabanı ve mevcut özelliklerle ilgili pek çok ödün vermek zorunda kalır. Hatta bazıları işi aşırı basitleştirirken arka planda güvenlik açıkları da barındırır.

**FastAPI**, hiçbir veritabanı, veri modeli veya araç konusunda ödün vermez.
