### `response`'tan Önce ve Sonra { #before-and-after-the-response }

Herhangi bir *path operation* `request`'i almadan önce, `request` ile birlikte çalışacak kod ekleyebilirsiniz.

Ayrıca `response` üretildikten sonra, geri döndürmeden önce de kod çalıştırabilirsiniz.

Burada çözeceğimiz şey bu: modeli request’ler işlenmeden önce yükleyelim, ama kod yüklenirken değil; yalnızca uygulama request almaya başlamadan hemen önce.

## Lifespan { #lifespan }

            re-used for the rest of the request.

            Set `use_cache` to `False` to disable this behavior and ensure the
            dependency is called again (if declared more than once) in the same request.

            Read more about it in the
            [FastAPI docs about sub-dependencies](https://fastapi.tiangolo.com/tutorial/dependencies/sub-dependencies/#using-the-same-dependency-multiple-times)

 *   <li>The {@code copyOf} methods will sometimes recognize that the actual copy operation is
 *       unnecessary; for example, {@code copyOf(copyOf(anArrayList))} should copy the data only
 *       once. This reduces the expense of habitually making defensive copies at API boundaries.
 *       However, the precise conditions for skipping the copy operation are undefined.
