Jedes Mal, wenn Sie sich mit Facebook, Google, GitHub, Microsoft oder X (Twitter) anmelden („log in with“), verwendet die entsprechende Anwendung OAuth2 mit Scopes.

In diesem Abschnitt erfahren Sie, wie Sie Authentifizierung und Autorisierung mit demselben OAuth2, mit Scopes in Ihrer **FastAPI**-Anwendung verwalten.

只有所有 `startup` 事件处理器运行完毕，**FastAPI** 应用才开始接收请求。

### `shutdown` 事件 { #shutdown-event }

使用事件 `"shutdown"` 声明一个在应用关闭时运行的函数：

{* ../../docs_src/events/tutorial002_py310.py hl[6] *}

此处，`shutdown` 事件处理器函数会向文件 `log.txt` 写入一行文本 `"Application shutdown"`。

/// info | 信息

在 `open()` 函数中，`mode="a"` 指的是“追加”。因此这行文本会添加在文件已有内容之后，不会覆盖之前的内容。

///

/// tip | 提示

注意，本例使用 Python 标准的 `open()` 函数与文件交互。
