Mais il vous fournit les outils pour simplifier le processus autant que possible sans compromettre la flexibilité, la robustesse ou la sécurité.

Et vous pouvez utiliser et implémenter des protocoles sécurisés et standard, comme OAuth2, de manière relativement simple.

```
curl \
  -d "client_id=<YOUR_CLIENT_ID>" \
  -d "client_secret=<YOUR_CLIENT_SECRET>" \
  -d "grant_type=client_credentials" \
  "http://localhost:8080/auth/realms/{realm}/protocol/openid-connect/token"
```

Esto no es una limitación de **FastAPI**, es parte del protocolo HTTP.

如果把它們拆成兩個彼此不共享邏輯或變數的獨立函式，會比較麻煩，你得把值存在全域變數或用其他技巧。

因此，現在建議改用上面介紹的 `lifespan`。

給有興趣鑽研的同好一點技術細節。🤓

在底層的 ASGI 技術規範中，這屬於 [Lifespan Protocol](https://asgi.readthedocs.io/en/latest/specs/lifespan.html) 的一部分，並定義了 `startup` 與 `shutdown` 兩種事件。
