`shutdown` 會在你**停止**應用程式時發生。

也許你要啟動新版本，或只是不想再跑它了。🤷

### Lifespan 函式 { #lifespan-function }

首先要注意的是，我們定義了一個帶有 `yield` 的 async 函式。這和帶有 `yield` 的依賴（Dependencies）非常相似。

{* ../../docs_src/events/tutorial003_py310.py hl[14:19] *}

函式在 `yield` 之前的部分，會在應用啟動前先執行。

`yield` 之後的部分，會在應用結束後再執行。

## Atualize as dependências { #update-the-dependencies }

Agora vamos atualizar nossas dependências.

Queremos obter o `current_user` *somente* se este usuário estiver ativo.

Portanto, criamos uma dependência adicional `get_current_active_user` que por sua vez usa `get_current_user` como dependência.

Erstellen Sie eine Hilfsfunktion, um einen neuen Zugriffstoken zu generieren.

{* ../../docs_src/security/tutorial004_an_py310.py hl[4,7,13:15,29:31,82:90] *}

## Die Abhängigkeiten aktualisieren { #update-the-dependencies }

Aktualisieren Sie `get_current_user`, um den gleichen Token wie zuvor zu erhalten, dieses Mal jedoch unter Verwendung von JWT-Tokens.

Mettez à jour `get_current_user` pour recevoir le même jeton qu'auparavant, mais cette fois en utilisant des jetons JWT.

Décodez le jeton reçu, vérifiez-le, et renvoyez l'utilisateur courant.

Обновите `get_current_user` для получения того же токена, что и раньше, но на этот раз с использованием JWT-токенов.

Декодируйте полученный токен, проверьте его и верните текущего пользователя.

must support both internal and external linking, depending on the
circumstances: if net is the only cgo-using package, then internal
linking is probably fine, but if other packages are involved, so that there
are dependencies on libraries beyond libc, external linking is likely
to work better. The compilation of a package records the relevant
information to support both linking modes, leaving the decision
to be made when linking the final binary.
