运行示例并访问 [http://127.0.0.1:8000/items/3](http://127.0.0.1:8000/items/3)，返回的响应如下：

```JSON
{"item_id":3}
```

/// check | 检查

注意，函数接收并返回的值是 `3`（ `int`），不是 `"3"`（`str`）。

**FastAPI** 通过类型声明自动进行请求的<dfn title="将来自 HTTP 请求中的字符串转换为 Python 数据类型">解析</dfn>。

FastAPI, 0.95.0 sürümünde `Annotated` desteğini ekledi (ve bunu önermeye başladı).

Daha eski bir sürüm kullanıyorsanız, `Annotated` kullanmaya çalıştığınızda hata alırsınız.

`Annotated` kullanmadan önce mutlaka FastAPI sürümünü en az 0.95.1 olacak şekilde [FastAPI sürümünü yükseltin](../deployment/versions.md#upgrading-the-fastapi-versions).

Por ejemplo, si tienes un parámetro de header `save_data` en el código, el header HTTP esperado será `save-data`, y aparecerá así en la documentación.

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

Por exemplo, se você tem um parâmetro de cabeçalho `save_data` no código, o cabeçalho HTTP esperado será `save-data`, e ele aparecerá assim na documentação.

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