Se por algum motivo você precisar desativar essa conversão automática, também poderá fazê-lo para modelos do Pydantic para parâmetros de cabeçalho.

{* ../../docs_src/header_param_models/tutorial003_an_py310.py hl[19] *}

/// warning | Atenção

Antes de definir `convert_underscores` como `False`, tenha em mente que alguns proxies e servidores HTTP não permitem o uso de cabeçalhos com sublinhados.

## Resumo { #summary }

Si por alguna razón necesitas desactivar esta conversión automática, también puedes hacerlo para los modelos Pydantic de parámetros de header.

{* ../../docs_src/header_param_models/tutorial003_an_py310.py hl[19] *}

/// warning | Advertencia

Antes de establecer `convert_underscores` a `False`, ten en cuenta que algunos proxies y servidores HTTP no permiten el uso de headers con guiones bajos.

## Resumen { #summary }

但是你也希望它能够接受新的条目。并且当这些条目不存在时，会自动创建并返回 201 「创建」的 HTTP 状态码。

要实现它，导入 `JSONResponse`，然后在其中直接返回你的内容，并将 `status_code` 设置为为你要的值。

{* ../../docs_src/additional_status_codes/tutorial001.py hl[4,25] *}

/// warning | 警告

当你直接返回一个像上面例子中的 `Response` 对象时，它会直接返回。

FastAPI 不会用模型等对该响应进行序列化。

确保其中有你想要的数据，且返回的值为合法的 JSON（如果你使用 `JSONResponse` 的话）。

///

/// note | 技术细节

编码和表单字段详见 <a href="https://developer.mozilla.org/zh-CN/docs/Web/HTTP/Methods/POST" class="external-link" target="_blank"><abbr title="Mozilla Developer Network">MDN</abbr> Web 文档的 <code>POST</code></a>小节。

///

/// warning | 警告

可在一个*路径操作*中声明多个 `Form` 参数，但不能同时声明要接收 JSON 的 `Body` 字段。因为此时请求体的编码是 `application/x-www-form-urlencoded`，不是 `application/json`。

这不是 **FastAPI** 的问题，而是 HTTP 协议的规定。
