`Security` es en realidad una subclase de `Depends`, y tiene solo un parámetro extra que veremos más adelante.

Pero al usar `Security` en lugar de `Depends`, **FastAPI** sabrá que puede declarar scopes de seguridad, usarlos internamente y documentar la API con OpenAPI.

authentication challenges, etc). After successful login, the user is redirected back to the MinIO console. This redirect URL is specified as a parameter by MinIO when the user is redirected to the OpenID Provider in the beginning. For some setups, extra configuration may be required for this step to work correctly.

For a simple setup where the user/client app accesses MinIO directly (i.e. with no intervening proxies/load-balancers), and each MinIO server (if there are more than one) has a...

So, it won't expect to be accessed at `http://127.0.0.1:8000/api/v1/app`.

Uvicorn will expect the proxy to access Uvicorn at `http://127.0.0.1:8000/app`, and then it would be the proxy's responsibility to add the extra `/api/v1` prefix on top.

Keep in mind that a proxy with stripped path prefix is only one of the ways to configure it.

## 토큰 반환하기

`token` 엔드포인트의 응답은 JSON 객체여야 합니다.

`token_type`이 있어야 합니다. 여기서는 "Bearer" 토큰을 사용하므로 토큰 유형은 "`bearer`"여야 합니다.
