可用同一个「表单字段」发送含多个文件的「表单数据」。

上传多个文件时，要声明含 `bytes` 或 `UploadFile` 的列表（`List`）：

//// tab | Python 3.9+

```Python hl_lines="8  13"
{!> ../../docs_src/request_files/tutorial002_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="10  15"
{!> ../../docs_src/request_files/tutorial002.py!}
```

////

接收的也是含 `bytes` 或 `UploadFile` 的列表（`list`）。
