O **FastAPI** pegará este modelo, gerará o esquema JSON dele e incluirá no local correto do OpenAPI.

Por exemplo, para declarar um outro retorno com o status code `404` e um modelo do Pydantic chamado `Message`, você pode escrever:

{* ../../docs_src/additional_responses/tutorial001.py hl[18,22] *}

/// note | Nota

Lembre-se que você deve retornar o `JSONResponse` diretamente.

        responseData.setHttpStatusCode(404);
        responseData.setUrl("http://example.com/");
        responseData.setMimeType("text/plain");
        return responseData;
    }

    private ResponseData getTestData4() {
        final ResponseData responseData = new ResponseData();
        responseData.setHttpStatusCode(404);
        responseData.setUrl("https://example.com/");

您可以向路径操作装饰器传递参数 `responses` 。

它接收一个 `dict`，键是每个响应的状态代码（如`200`），值是包含每个响应信息的其他 `dict`。

每个响应字典都可以有一个关键模型，其中包含一个 `Pydantic` 模型，就像 `response_model` 一样。

**FastAPI**将采用该模型，生成其`JSON Schema`并将其包含在`OpenAPI`中的正确位置。

例如，要声明另一个具有状态码 `404` 和`Pydantic`模型 `Message` 的响应，可以写：
{* ../../docs_src/additional_responses/tutorial001.py hl[18,22] *}

/// note

请记住，您必须直接返回 `JSONResponse` 。

///

/// info

`model` 密钥不是OpenAPI的一部分。

Los códigos de estado en el rango de 400 significan que hubo un error por parte del cliente.

¿Recuerdas todos esos errores de **"404 Not Found"** (y chistes)?

## Usa `HTTPException`

Para devolver responses HTTP con errores al cliente, usa `HTTPException`.

### Importa `HTTPException`
