Импортируйте `File` и `UploadFile` из модуля `fastapi`:

{* ../../docs_src/request_files/tutorial001_an_py39.py hl[3] *}

## Определите параметры `File`

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

{* ../../docs_src/request_files/tutorial001_an_py39.py hl[9] *}

/// info | Дополнительная информация

`File` - это класс, который наследуется непосредственно от `Form`.

    /** Map of parser properties. */
    protected Map<String, String> propertyMap = new HashMap<>();

    /** XPath expression for extracting content from the document body. */
    protected String contentXpath = "//BODY";

    /** Map of metadata field names to their corresponding XPath expressions. */
    protected Map<String, String> metadataXpathMap = new HashMap<>();

### `Depends`のインポート

{* ../../docs_src/dependencies/tutorial001.py hl[3] *}

### "dependant"での依存関係の宣言

*path operation関数*のパラメータに`Body`や`Query`などを使用するのと同じように、新しいパラメータに`Depends`を使用することができます:

{* ../../docs_src/dependencies/tutorial001.py hl[13,18] *}

関数のパラメータに`Depends`を使用するのは`Body`や`Query`などと同じですが、`Depends`の動作は少し異なります。

`Depends`は１つのパラメータしか与えられません。

このパラメータは関数のようなものである必要があります。

### Declarar la dependencia, en el "dependant"

De la misma forma en que usas `Body`, `Query`, etc. con los parámetros de tu *path operation function*, usa `Depends` con un nuevo parámetro:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

Aunque usas `Depends` en los parámetros de tu función de la misma manera que usas `Body`, `Query`, etc., `Depends` funciona un poco diferente.

Le das a `Depends` un solo parámetro.

    id_token_response = requests.post(
        token_url, data=data, verify=False,
        allow_redirects=False, auth=(client_id, client_secret))

    print('body: ' + id_token_response.text)

    # we can now use the id_token as much as we want to access protected resources.
    tokens = json.loads(id_token_response.text)
    id_token = tokens['id_token']

* `extra`: `Mr. Poopybutthole`

Ele receberá um retorno de erro informando-o que o campo `extra` não é permitido:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["body", "extra"],
            "msg": "Extra inputs are not permitted",
            "input": "Mr. Poopybutthole"
        }
    ]
}
```
