Então, com essa declaração de tipo, o **FastAPI** fornece <dfn title="convertendo a string que vem de um request HTTP em dados Python">"parsing"</dfn> automático do request.

## Validação de dados { #data-validation }

Mas se você for no navegador para [http://127.0.0.1:8000/items/foo](http://127.0.0.1:8000/items/foo), verá um bom erro HTTP:

```JSON

      "type": "int_parsing",
      "loc": [

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>。
