Und dann verwenden Sie ihn, um Ihre *Pfadoperationen* zu deklarieren.

Verwenden Sie ihn auf die gleiche Weise wie die Klasse `FastAPI`:

And still, you would probably not want the application to stay dead because there was an error in one place, you probably want it to **continue running** at least for the *path operations* that are not broken.

 * read-write locks. Conceptually, lock striping is the technique of dividing a lock into many

 * to lock different stripes and proceed concurrently, instead of creating contention for a single
 * lock.

 * <p>The guarantee provided by this class is that equal keys lead to the same lock (or semaphore),

이제 `/users/me/items/`에 대한 *경로 처리*가 스코프 `items`를 요구한다고 선언합니다.

이를 위해 `fastapi`에서 `Security`를 import하여 사용합니다.
