## Use it

Now you can declare your dependency using this class.

=== "Python 3.10+"

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial002_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial002_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="20"

E você também pode declarar parâmetros de corpo como opcionais, definindo o valor padrão com `None`:

=== "Python 3.10+"

    ```Python hl_lines="17-19"
    {!> ../../../docs_src/body_multiple_params/tutorial001_py310.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="19-21"
    {!> ../../../docs_src/body_multiple_params/tutorial001.py!}
    ```

!!! note "Nota"

    ```

=== "Python 3.8+"

    ```Python hl_lines="19-21"
    {!> ../../../docs_src/body_multiple_params/tutorial001_an.py!}
    ```

=== "Python 3.10+ non-Annotated"

    !!! tip "Заметка"
        Рекомендуется использовать `Annotated` версию, если это возможно.

    ```Python hl_lines="17-19"
    {!> ../../../docs_src/body_multiple_params/tutorial001_py310.py!}
    ```

      {{- with .Values.tolerations }}
      tolerations: {{- toYaml . | nindent 8 }}
      {{- end }}
      {{- if and (gt $replicas 1) (ge .Capabilities.KubeVersion.Major "1") (ge .Capabilities.KubeVersion.Minor "19") }}
      {{- with .Values.topologySpreadConstraints }}
      topologySpreadConstraints: {{- toYaml . | nindent 8 }}
      {{- end }}
      {{- end }}
      volumes:
        - name: minio-user
          secret:

    {!> ../../../docs_src/schema_extra_example/tutorial004_an.py!}
    ```

=== "Python 3.10+ non-Annotated"

    !!! tip
        Prefer to use the `Annotated` version if possible.

    ```Python hl_lines="19-34"
    {!> ../../../docs_src/schema_extra_example/tutorial004_py310.py!}
    ```

=== "Python 3.8+ non-Annotated"

    !!! tip
        Prefer to use the `Annotated` version if possible.

    {!> ../../../docs_src/security/tutorial002_py310.py!}
    ```

## 유저 가져오기

`get_current_user`는 토큰을 `str`로 취하고 Pydantic `User` 모델을 반환하는 우리가 만든 (가짜) 유틸리티 함수를 사용합니다.

=== "파이썬 3.7 이상"

    ```Python hl_lines="19-22  26-27"
    {!> ../../../docs_src/security/tutorial002.py!}
    ```

=== "파이썬 3.10 이상"

    ```Python hl_lines="17-20  24-25"
    {!> ../../../docs_src/security/tutorial002_py310.py!}
    ```

*Декоратор операции пути* получает необязательный аргумент `dependencies`.

Это должен быть `list` состоящий из `Depends()`:

=== "Python 3.9+"

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial006_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="18"
    {!> ../../../docs_src/dependencies/tutorial006_an.py!}
    ```

It won't show up in the documentation, but other tools (such as Sphinx) will be able to use the rest.

```Python hl_lines="19-29"
{!../../../docs_src/path_operation_advanced_configuration/tutorial004.py!}
```

## Additional Responses

You probably have seen how to declare the `response_model` and `status_code` for a *path operation*.

### Função _lifespan_

A primeira coisa a notar, é que estamos definindo uma função assíncrona com `yield`. Isso é muito semelhante à Dependências com `yield`.

```Python hl_lines="14-19"
{!../../../docs_src/events/tutorial003.py!}
```

A primeira parte da função, antes do `yield`, será  executada **antes** da aplicação inicializar.

### Lifespan function

The first thing to notice, is that we are defining an async function with `yield`. This is very similar to Dependencies with `yield`.

```Python hl_lines="14-19"
{!../../../docs_src/events/tutorial003.py!}
```

The first part of the function, before the `yield`, will be executed **before** the application starts.
