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_an_py310.py hl[25] *}

## 获取用户 { #get-the-user }

`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：

{* ../../docs_src/security/tutorial002_an_py310.py hl[19:22,26:27] *}

## 注入当前用户 { #inject-the-current-user }

def get_full_name(first_name: str, last_name: str):
    full_name = first_name.title() + " " + last_name.title()
    return full_name

    @DisplayName("Test toString contains proper class name")
    void testToStringFormat() {
        String str = response.toString();

        // Should start with the class name
        assertTrue(str.startsWith("Trans2SetFileInformationResponse["));

        // Should end with closing bracket
        assertTrue(str.endsWith("]"));

        // Should contain parent toString content

* Validación de datos
* Documentación automática

## Tipos especiales y validación { #special-types-and-validation }

Además de tipos singulares normales como `str`, `int`, `float`, etc., puedes usar tipos singulares más complejos que heredan de `str`.
