ComputeCustomRoutes
응답의 경로 토큰은
Navigation SDK에 연결하여 탐색 세션을 시작합니다.
Routes Preferred API에서 반환한 경로를 따릅니다.
경로 토큰은 만료되지 않지만 동적 도로 상황으로 인해 경로가 생성되었습니다.
는 원래 경로와 다를 수 있습니다. Google은
토큰 생성 후 몇 분 내에 경로 토큰을 사용하는 것이 좋습니다.
경로 토큰에 대한 자세한 내용은 Android용 Navigation SDK를 참조하세요. 및 iOS용 Navigation SDK 문서를 참조하세요.

이 기능은 routes.travelAdvisory.tollInfo
필드 마스크로 사용 설정됩니다.
요청 시 명시됩니다. 톨 패스는 route_modifiers

필드를 확인합니다. 반환된 통행료는
지정된 패스입니다. 패스를 두 개 이상 지정할 경우 가장 저렴한 패스는
가격이 반환됩니다.

필드 마스크의 한 쌍입니다. 이는 예상되는 동작입니다.
API의 '비용'을 계산할 수 없습니다.
일반적으로 응답에 tollInfo
필드가 있으면
경로에 유료 도로가 있다는 것을 의미합니다.
