이 문서에서는 Maps JavaScript API의 웹사이트 콘텐츠 보안 정책(CSP)을 구성하는 방법에 관한 권장사항을 제공합니다. 최종 사용자는 다양한 브라우저 유형과 버전을 사용하므로 개발자는 이 예를 참고하여 추가 CSP 위반이 발생하지 않도록 세부적으로 조정하는 것이 좋습니다.
허용 목록 CSP 대신 엄격한 CSP를 사용하여 보안 공격의 가능성을 줄이는 것이 좋습니다.
Maps JavaScript API는 nonce 기반의 엄격한 CSP 사용을 지원합니다.
웹사이트는 script 및 style 요소를 모두 nonce 값으로 채워야 합니다.
내부적으로 Maps JavaScript API는 이러한 첫 번째 요소를 찾아 API 스크립트에서 삽입한 스타일 또는 스크립트 요소에 nonce 값을 각각 적용합니다.
