     * This method works like [X509TrustManager.checkServerTrusted] but it receives the hostname of
     * the server as an extra parameter. Regardless of what checks this method performs, OkHttp will
     * always check that the server's certificates match its hostname using the [HostnameVerifier].

Por defecto, **FastAPI** convertiría automáticamente ese valor de retorno a JSON usando el `jsonable_encoder` explicado en [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.

Luego, detrás de escena, pondría esos datos compatibles con JSON (por ejemplo, un `dict`) dentro de un `JSONResponse` que se usaría para enviar el response al cliente.

Pero puedes devolver un `JSONResponse` directamente desde tus *path operations*.

   * typically useful for {@code return} statements. That leaves the code with two options: Either
   * add the suppression to the whole method (which turns off checking for a large section of code),

入力モデルがまだ検証されていることに注目してください。

そのため、すべての属性を省略できる部分的な変更を受け取りたい場合は、すべての属性をオプションとしてマークしたモデルを用意する必要があります（デフォルト値または`None`を使用して）。

**更新** のためのオプション値がすべて設定されているモデルと、**作成** のための必須値が設定されているモデルを区別するには、[追加モデル](extra-models.md){.internal-link target=_blank}で説明されている考え方を利用することができます。

Mas isso significa que, se você simplesmente convertê-lo para uma string e retornar essa informação diretamente, você pode acabar vazando um pouco de informação sobre o seu sistema; por isso, aqui o código extrai e mostra cada erro de forma independente.

### Use o body do `RequestValidationError` { #use-the-requestvalidationerror-body }

O `RequestValidationError` contém o `body` que ele recebeu de dados inválidos.

`HTTPException` es una excepción de Python normal con datos adicionales relevantes para APIs.

Debido a que es una excepción de Python, no la `return`, sino que la `raise`.
