Но FastAPI (точнее, Starlette) предоставляет более простой способ, который гарантирует корректную обработку внутренних ошибок сервера и корректную работу пользовательских обработчиков исключений.

Для этого используйте `app.add_middleware()` (как в примере с CORS).

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

app = FastAPI()

# 하위 응용프로그램 - 마운트

만약 각각의 독립적인 OpenAPI와 문서 UI를 갖는 두 개의 독립적인 FastAPI 응용프로그램이 필요하다면, 메인 어플리케이션에 하나 (또는 그 이상의) 하위-응용프로그램(들)을 “마운트"해서 사용할 수 있습니다.

## **FastAPI** 응용프로그램 마운트

“마운트"이란 완전히 “독립적인" 응용프로그램을 특정 경로에 추가하여 해당 하위 응용프로그램에서 선언된 *경로 동작*을 통해 해당 경로 아래에 있는 모든 작업들을 처리할 수 있도록 하는 것을 의미합니다.

### 최상단 응용프로그램

먼저, 메인, 최상단의 **FastAPI** 응용프로그램과 이것의 *경로 동작*을 생성합니다:

{* ../../docs_src/sub_applications/tutorial001.py hl[3, 6:8] *}

### 하위 응용프로그램

Par exemple, en étendant le modèle précédent, vous pouvez vouloir ajouter un paramètre `importance` dans le même body, en plus des paramètres `item` et `user`.

Si vous le déclarez tel quel, comme c'est une valeur [scalaire](https://docs.github.com/fr/graphql/reference/scalars), **FastAPI** supposera qu'il s'agit d'un paramètre de requête (`Query`).

        run: |
          cd dist
          tar xvf fastapi*.tar.gz
      - name: Install test dependencies
        run: |
          cd dist/fastapi*/
          pip install -r requirements-tests.txt
        env:
          TIANGOLO_BUILD_PACKAGE: ${{ matrix.package }}
      - name: Run source distribution tests
        run: |
          cd dist/fastapi*/
          bash scripts/test.sh
      - name: Build wheel distribution

**FastAPI** stellt denselben `starlette.testclient` auch via `fastapi.testclient` bereit, als Annehmlichkeit für Sie, den Entwickler. Es kommt aber tatsächlich direkt von Starlette.
