Neste caso, o cabeçalho HTTP `Content-Type` será definido como `text/html`.

E será documentado como tal no OpenAPI.

### Retornando uma `Response` { #return-a-response }

Como visto em [Retornando uma Resposta Diretamente](response-directly.md){.internal-link target=_blank}, você também pode sobrescrever a resposta diretamente na sua *operação de rota*, ao retornar ela.

        response.setHeaders(headers);

        String firstValue = response.getHeaderValue("Accept");

        assertEquals("application/json", firstValue); // Should return first value
    }

    @Test
    public void testContentCache() {
        CurlResponse response = new CurlResponse();
        byte[] data = "test content".getBytes();

/// info

`File` is a class that inherits directly from `Form`.

But remember that when you import `Query`, `Path`, `File` and others from `fastapi`, those are actually functions that return special classes.

///

/// tip

To declare File bodies, you need to use `File`, because otherwise the parameters would be interpreted as query parameters or body (JSON) parameters.

`async def`로 생성된 함수 내부에서만 `await`를 사용할 수 있습니다.

데이터베이스, API, 파일시스템 등과 의사소통하는 제3의 라이브러리를 사용하고, 그것이 `await`를 지원하지 않는 경우(현재 거의 모든 데이터베이스 라이브러리가 그러합니다), *경로 작동 함수*를 일반적인 `def`를 사용해 선언하십시오:

```Python hl_lines="2"

def results():
    results = some_library()
