👆 💪 🔬 📁 📂 👩‍💻 ⚙️ `File`.

!!! info
    📨 📂 📁, 🥇 ❎ <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

    🤶 Ⓜ. `pip install python-multipart`.

    👉 ↩️ 📂 📁 📨 "📨 💽".

## 🗄 `File`

🗄 `File` &amp; `UploadFile` ⚪️➡️ `fastapi`:

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

## 🔬 `File` 🔢

```

## `File` 매개변수 정의

`Body` 및 `Form` 과 동일한 방식으로 파일의 매개변수를 생성합니다:

```Python hl_lines="7"
{!../../../docs_src/request_files/tutorial001.py!}
```

!!! info "정보"
    `File` 은 `Form` 으로부터 직접 상속된 클래스입니다.

    하지만 `fastapi`로부터 `Query`, `Path`, `File` 등을 임포트 할 때, 이것들은 특별한 클래스들을 반환하는 함수라는 것을 기억하기 바랍니다.

!!! tip "팁"
    File의 본문을 선언할 때, 매개변수가 쿼리 매개변수 또는 본문(JSON) 매개변수로 해석되는  것을 방지하기 위해 `File` 을 사용해야합니다.

# 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

    {!> ../../../docs_src/request_files/tutorial001.py!}
    ```

## Определите параметры `File`

Создайте параметры `File` так же, как вы это делаете для `Body` или `Form`:

=== "Python 3.9+"

    ```Python hl_lines="9"
    {!> ../../../docs_src/request_files/tutorial001_an_py39.py!}
    ```

=== "Python 3.6+"

    ```Python hl_lines="8"
    {!> ../../../docs_src/request_files/tutorial001_an.py!}
    ```

    grep -e "\.py$" $BATS_FILE_TMPDIR/changed_files > $BATS_TEST_TMPDIR/files || true
    if [[ ! -s $BATS_TEST_TMPDIR/files ]]; then return 0; fi
    xargs -a $BATS_TEST_TMPDIR/files -n1 -P $(nproc --all) \
        python -m pylint --rcfile=tensorflow/tools/ci_build/pylintrc --score false \
        | grep -v "**** Module" \
        | tee $BATS_TEST_TMPDIR/needs_help.txt
    [[ ! -s $BATS_TEST_TMPDIR/needs_help.txt ]]
}

teardown_file() {

## 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!}
    ```

=== "Python 3.6+ без Annotated"

# Request Forms and Files

You can define files and form fields at the same time using `File` and `Form`.

!!! info
    To receive uploaded files and/or form data, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

    E.g. `pip install python-multipart`.
