"name": "The Baz"
        }
    ]
}
```

/// info | "정보"

`images` 키가 어떻게 이미지 객체 리스트를 갖는지 주목하세요.

///

## 깊게 중첩된 모델

단독으로 깊게 중첩된 모델을 정의할 수 있습니다:

```Python hl_lines="9  14  20  23  27"
{!../../docs_src/body_nested_models/tutorial007.py!}
```

/// info | "정보"

`Offer`가 선택사항 `Image` 리스트를 차례로 갖는 `Item` 리스트를 어떻게 가지고 있는지 주목하세요

///

            "name": "The Foo live"
        },
        {
            "url": "http://example.com/dave.jpg",
            "name": "The Baz"
        }
    ]
}
```

/// info

Notice how the `images` key now has a list of image objects.

///

## Deeply nested models

You can define arbitrarily deeply nested models:

//// tab | Python 3.10+

# 请求文件

`File` 用于定义客户端的上传文件。

/// info | "说明"

因为上传文件以「表单数据」形式发送。

所以接收上传文件，要预先安装 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>。

例如： `pip install python-multipart`。

///

## 导入 `File`

从 `fastapi` 导入 `File` 和 `UploadFile`：

```Python hl_lines="1"
{!../../docs_src/request_files/tutorial001.py!}
```

## 定义 `File` 参数

### Check the automatic API docs

Now, run the `fastapi` command with your file:

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

And open the docs at <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.
