Ensuite, pour tout appel ultérieur de `get_settings()` dans les dépendances pour les requêtes suivantes, au lieu d'exécuter le code interne de `get_settings()` et de créer un nouvel objet `Settings`, il renverra le même objet que celui retourné au premier appel, encore et encore.

`@lru_cache` konusunu birazdan ele alacağız.

Şimdilik `get_settings()`'in normal bir fonksiyon olduğunu varsayabilirsiniz.

///

Sonra bunu dependency olarak *path operation function*'dan talep edebilir ve ihtiyaç duyduğumuz her yerde kullanabiliriz.

from functools import lru_cache

from fastapi import Depends, FastAPI

from .config import Settings

app = FastAPI()


@lru_cache
def get_settings():
    return Settings()


@app.get("/info")
async def info(settings: Settings = Depends(get_settings)):
    return {
        "app_name": settings.app_name,
        "admin_email": settings.admin_email,
        "items_per_user": settings.items_per_user,

from functools import lru_cache

def get_settings():
    return config.Settings()


@app.get("/info")
async def info(settings: config.Settings = Depends(get_settings)):
    return {
        "app_name": settings.app_name,

        "items_per_user": settings.items_per_user,

{* ../../docs_src/settings/app03_an_py310/main.py hl[1,11] *}

Entonces, para cualquier llamada subsiguiente de `get_settings()` en las dependencias de los próximos requests, en lugar de ejecutar el código interno de `get_settings()` y crear un nuevo objeto `Settings`, devolverá el mismo objeto que fue devuelto en la primera llamada, una y otra vez.

의존성 함수가 단순히 다음과 같다면:

```Python
def get_settings():
    return Settings()
```

요청마다 객체를 생성하게 되고, 요청마다 `.env` 파일을 읽게 됩니다. ⚠️

하지만 위에 `@lru_cache` 데코레이터를 사용하고 있으므로, `Settings` 객체는 최초 호출 시 딱 한 번만 생성됩니다. ✔️

{* ../../docs_src/settings/app03_an_py310/main.py hl[1,11] *}

그 다음 요청들에서 의존성으로 `get_settings()`가 다시 호출될 때마다, `get_settings()`의 내부 코드를 실행해서 새 `Settings` 객체를 만드는 대신, 첫 호출에서 반환된 동일한 객체를 계속 반환합니다.
