# Swagger UI 구성

추가적인 <a href="https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration/" class="external-link" target="_blank">Swagger UI 매개변수</a>를 구성할 수 있습니다.

구성을 하려면, `FastAPI()` 앱 객체를 생성할 때 또는 `get_swagger_ui_html()` 함수에 `swagger_ui_parameters` 인수를 전달하십시오.

`swagger_ui_parameters`는 Swagger UI에 직접 전달된 구성을 포함하는 딕셔너리를 받습니다.

FastAPI는 이 구성을 **JSON** 형식으로 변환하여 JavaScript와 호환되도록 합니다. 이는 Swagger UI에서 필요로 하는 형식입니다.
