| Add admin feature | `app/web/admin/*/`, `app/service/`, `webapp/WEB-INF/view/admin/` |
| Add API endpoint | `api/`, `app/web/api/` |

### メソッドの上書き { #override-the-method }

これで、`.openapi()` メソッドを新しい関数に置き換えられます。

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[29] *}

### 確認 { #check-it }

[http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc) にアクセスすると、カスタムロゴ（この例では **FastAPI** のロゴ）が使われていることが確認できます:

{* ../../docs_src/security/tutorial006_an_py310.py hl[4,8,12] *}

第一次打开 URL（或在 API 文档中点击 **Execute** 按钮）时，浏览器要求输入用户名与密码：

<img src="/img/tutorial/security/image12.png">

## 检查用户名 { #check-the-username }

以下是更完整的示例。

使用依赖项检查用户名与密码是否正确。

为此要使用 Python 标准模块 [`secrets`](https://docs.python.org/3/library/secrets.html) 检查用户名与密码。

### Проверьте документацию { #check-the-docs }

Теперь, если вы проверите документацию, вы увидите всю дополнительную информацию:
