Nevertheless, although we are not using the default integrated functionality, we are still using a Pydantic model to manually generate the JSON Schema for the data that we want to receive in YAML.

Then we use the request directly, and extract the body as `bytes`. This means that FastAPI won't even try to parse the request payload as JSON.

 * error codes, constants and text messages like "The device is not ready"
 * are provided.
 * <p>
 * The jCIFS client maps DOS error codes to NTSTATUS codes. This means that
 * the user may receive a different error from a legacy server than that of
 * a newer variant such as Windows NT and above. If you should encounter
 * such a case, please report it to jcifs at samba dot org and we will
 * change the mapping.

/// note | Nota

Observe que `status_code` é um parâmetro do método "decorador" (`get`, `post`, etc). Não da sua função de *operação de rota*, como todos os parâmetros e corpo.

///

O parâmetro `status_code` recebe um número com o código de status HTTP.

/// info | Informação

`status_code` também pode receber um `IntEnum`, como [`http.HTTPStatus`](https://docs.python.org/3/library/http.html#http.HTTPStatus) do Python.

///

Você também pode utilizar o parâmetro `status_code` combinado com o parâmetro `response_class`:

### `StreamingResponse` { #streamingresponse }

Recebe um gerador assíncrono ou um gerador/iterador comum (uma função com `yield`) e transmite (stream) o corpo da resposta.

### Events with Retries and Follow-Ups

OkHttp is resilient and can automatically recover from some connectivity failures. In this case, the `connectFailed()` event is not terminal and not followed by `callFailed()`. Event listeners will receive multiple events of the same type when retries are attempted.
