    ```

=== "Python 3.8+"

    ```Python hl_lines="18"

```Python
item: Item = Body(embed=True)
```

so wie in:

    ```Python hl_lines="17"
    {!> ../../../docs_src/body_multiple_params/tutorial005_an_py310.py!}
    ```

    ```Python hl_lines="17"

=== "Python 3.8+"

    ```Python hl_lines="18"

Create new canned policy file `getonly.json`. This policy enables users to download all objects under `my-bucketname`.

```json

# 使用数据类

FastAPI 基于 **Pydantic** 构建，前文已经介绍过如何使用 Pydantic 模型声明请求与响应。

但 FastAPI 还可以使用数据类（<a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a>）：

```Python hl_lines="1  7-12  19-20"
{!../../../docs_src/dataclasses/tutorial001.py!}
```
