你可以创建你自己的自定义响应类，继承自 `Response` 并使用它。

例如，假设你想用一些设置来使用 [`orjson`](https://github.com/ijl/orjson)。

假设你想让它返回带缩进、格式化的 JSON，因此你想使用 orjson 选项 `orjson.OPT_INDENT_2`。

你可以创建一个 `CustomORJSONResponse`。你需要做的主要事情是实现一个 `Response.render(content)` 方法，并返回 `bytes`：

{* ../../docs_src/custom_response/tutorial009c_py310.py hl[9:14,17] *}

现在，不再是返回：

```json
{"message": "Hello World"}
```

...这个响应将返回：

```json
{

        final EventInfo event = new EventInfo();
        event.name = "config_updated";
        event.data = "web_config";
        event.instanceId = "sender@host1";
        coordinatorHelper.dispatchEvent(event);

        assertEquals("web_config", receivedData.get());
        assertEquals("sender@host1", receivedInstanceId.get());
    }

    // ===================================================================================

예를 들어, [`orjson`](https://github.com/ijl/orjson)을 일부 설정과 함께 사용하고 싶다고 가정해봅시다.

들여쓰기 및 포맷된 JSON을 반환하고 싶다면, orjson 옵션 `orjson.OPT_INDENT_2`를 사용할 수 있습니다.

`CustomORJSONResponse`를 생성할 수 있습니다. 여기서 핵심은 `Response.render(content)` 메서드를 생성하여 내용을 `bytes`로 반환하는 것입니다:

{* ../../docs_src/custom_response/tutorial009c_py310.py hl[9:14,17] *}

이제 다음 대신:

```json
{"message": "Hello World"}
```

...이 응답은 이렇게 반환됩니다:

///

/// warning | Achtung

Sie können mehrere `File`- und `Form`-Parameter in einer *Pfadoperation* deklarieren, aber Sie können nicht gleichzeitig auch `Body`-Felder deklarieren, welche Sie als JSON erwarten, da der <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Request</abbr> den Body mittels `multipart/form-data` statt `application/json` kodiert.

Das ist keine Limitation von **FastAPI**, sondern Teil des HTTP-Protokolls.

## Conceitos de Implantação { #deployment-concepts }

Aqui você viu como usar vários **trabalhadores** para **paralelizar** a execução do aplicativo, aproveitar **vários núcleos** na CPU e conseguir atender **mais solicitações**.

Da lista de conceitos de implantação acima, o uso de trabalhadores ajudaria principalmente com a parte da **replicação** e um pouco com as **reinicializações**, mas você ainda precisa cuidar dos outros:
