本例把 `item_id` 的类型声明为 `int`。

/// check | 检查

类型声明将为函数提供错误检查、代码补全等编辑器支持。

## 数据<abbr title="也称为：序列化、解析">转换</abbr>

运行示例并访问 <a href="http://127.0.0.1:8000/items/3" class="external-link" target="_blank">http://127.0.0.1:8000/items/3</a>，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`）。

      "input": "foo"
    }
  ]
}
```

porque o parâmetro de path `item_id` tinha o valor `"foo"`, que não é um `int`.

O mesmo erro apareceria se você fornecesse um `float` em vez de um `int`, como em: <a href="http://127.0.0.1:8000/items/4.2" class="external-link" target="_blank">http://127.0.0.1:8000/items/4.2</a>
