## Установка пользовательских обработчиков исключений

Вы можете добавить пользовательские обработчики исключений с помощью <a href="https://www.starlette.io/exceptions/" class="external-link" target="_blank">то же самое исключение - утилиты от Starlette</a>.

Допустим, у вас есть пользовательское исключение `UnicornException`, которое вы (или используемая вами библиотека) можете `вызвать`.

# 교차 출처 리소스 공유

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORS 또는 "교차-출처 리소스 공유"</a>란, 브라우저에서 동작하는 프론트엔드가 자바스크립트로 코드로 백엔드와 통신하고, 백엔드는 해당 프론트엔드와 다른 "출처"에 존재하는 상황을 의미합니다.

## 출처

출처란 프로토콜(`http` , `https`), 도메인(`myapp.com`, `localhost`, `localhost.tiangolo.com` ), 그리고 포트(`80`, `443`, `8080` )의 조합을 의미합니다.

따라서, 아래는 모두 상이한 출처입니다:

* `http://localhost`
* `https://localhost`
