# 폼 및 파일 요청

`File` 과 `Form` 을 사용하여 파일과 폼을 함께 정의할 수 있습니다.

!!! info "정보"
    파일과 폼 데이터를 함께, 또는 각각 업로드하기 위해 먼저 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>를 설치해야합니다.

    예 ) `pip install python-multipart`.

## `File` 및 `Form` 업로드

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

## `File` 및 `Form` 매개변수 정의

Erstellen Sie Datei- und Formularparameter, so wie Sie es auch mit `Body` und `Query` machen würden:

=== "Python 3.9+"

    ```Python hl_lines="10-12"
    {!> ../../../docs_src/request_forms_and_files/tutorial001_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="9-11"
    {!> ../../../docs_src/request_forms_and_files/tutorial001_an.py!}
    ```

=== "Python 3.8+ nicht annotiert"

## 「フォームフィールド」について

HTMLフォーム（`<form></form>`）がサーバにデータを送信する方法は、通常、そのデータに「特別な」エンコーディングを使用していますが、これはJSONとは異なります。

**FastAPI** は、JSONの代わりにそのデータを適切な場所から読み込むようにします。

!!! note "技術詳細"
    フォームからのデータは通常、`application/x-www-form-urlencoded`の「media type」を使用してエンコードされます。

    しかし、フォームがファイルを含む場合は、`multipart/form-data`としてエンコードされます。ファイルの扱いについては次の章で説明します。

# 请求表单与文件

FastAPI 支持同时使用 `File` 和 `Form` 定义文件和表单字段。

!!! info "说明"

    接收上传文件或表单数据，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` 与 `Form`

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

## 定义 `File` 与 `Form` 参数

创建文件和表单参数的方式与 `Body` 和 `Query` 一样：

## Определите параметры `File` и `Form`

Создайте параметры файла и формы таким же образом, как для `Body` или `Query`:

=== "Python 3.9+"

    ```Python hl_lines="10-12"
    {!> ../../../docs_src/request_forms_and_files/tutorial001_an_py39.py!}
    ```

=== "Python 3.6+"

    ```Python hl_lines="9-11"
    {!> ../../../docs_src/request_forms_and_files/tutorial001_an.py!}
    ```

**FastAPI** will make sure to read that data from the right place instead of JSON.

!!! note "Technical Details"
    Data from forms is normally encoded using the "media type" `application/x-www-form-urlencoded` when it doesn't include files.

    But when the form includes files, it is encoded as `multipart/form-data`. If you use `File`, **FastAPI** will know it has to get the files from the correct part of the body.
