创建 `get_current_user` 依赖项。

还记得依赖项支持子依赖项吗？

`get_current_user` 使用 `oauth2_scheme` 作为依赖项。

与之前直接在路径操作中的做法相同，新的 `get_current_user` 依赖项从子依赖项 `oauth2_scheme` 中接收 `str` 类型的 `token`：

{!../../../docs_src/security/tutorial002.py!}
```

## 获取用户

`get_current_user` 使用创建的（伪）工具函数，该函数接收 `str` 类型的令牌，并返回 Pydantic 的 `User` 模型：

```Python hl_lines="19-22  26-27"

`get_current_user`는 이전에 생성한 것과 동일한 `oauth2_scheme`과 종속성을 갖게 됩니다.

이전에 *경로 작동*에서 직접 수행했던 것과 동일하게 새 종속성 `get_current_user`는 하위 종속성 `oauth2_scheme`에서 `str`로 `token`을 수신합니다.

## Create models

Create Pydantic models for:

* Notes to be created (`NoteIn`).
* Notes to be returned (`Note`).
