javascript - Google Maps API(JS)在路点中使用PlaceId创建路线

仅当我使用LatLng或String参数，但我需要通过PlaceId创建它时，路由才会创建，但它不起作用

例:

directionsService.route({
        origin: {'placeId': 'ChIJc1lGdwfP20YR3lGOMZD-GTM'},
        destination: {'placeId': 'ChIJdTGhqsbP20YR6DZ2QMPnJk0'},
        waypoints: [{stopover: true, location: new google.maps.Place('ChIJRVj1dgPP20YRBWB4A_sUx_Q')}],
        optimizeWaypoints: true,
        travelMode: google.maps.TravelMode.DRIVING
    }

最佳答案

只需要传递 google.maps.Place 对象作为路标位置即可。
例如:

directionsService.route({
    origin: { placeId: "ChIJc1lGdwfP20YR3lGOMZD-GTM" },
    destination: { placeId: "ChIJdTGhqsbP20YR6DZ2QMPnJk0" },
    waypoints: [{ stopover: true, location: { placeId: "ChIJRVj1dgPP20YRBWB4A_sUx_Q" } }],
    optimizeWaypoints: true,
    travelMode: google.maps.TravelMode.DRIVING
}
