google-maps - 谷歌地图方向api考虑交通

Question

我正在尝试编写一个简单的脚本，以便通过考虑交通情况在谷歌表中计算两个位置之间的旅行时间。

我正在使用 google Maps API 的类 DirectionFinder。

我已经设法计算出旅行所需的时间，但无论我输入什么出发时间，我的旅行时间都保持不变。知道我在做什么错吗？使用此类甚至可以考虑流量吗？我是否需要成为业务用户才能访问此内容？

这是我的代码:

function DrivingSeconds(origin, destination, Y, M, D, H, S) {
  Utilities.sleep(1000);
  var time= new Date(Y,M,D,H,S);
  var directions = Maps.newDirectionFinder()
  .setDepart(time)
  .setOrigin(origin)
  .setDestination(destination)
  .setMode(Maps.DirectionFinder.Mode.DRIVING)
  .getDirections();
  return directions.routes[0].legs[0].duration.value;  
}

感谢您提供的任何建议! :)

Answer 1

来自谷歌文档:

For requests where the travel mode is driving: You can specify the departure_time to receive a route and trip duration (response field: duration_in_traffic) that take traffic conditions into account. This option is only available if the request contains a valid API key, or a valid Google Maps APIs Premium Plan client ID and signature. The departure_time must be set to the current time or some time in the future. It cannot be in the past.

所以是的，仅适用于高级用户。那么您的请求应如下所示:

var request = {
  origin: origin,
  destination: destination,
  drivingOptions: {
    departureTime: new Date(),
  },
  travelMode: google.maps.TravelMode[DRIVING]
};

var directionsService = new google.maps.DirectionsService();
directionsService.route(request, function(response,status) {
  if(status == google.maps.DirectionsStatus.OK) {
    console.log(response.routes[0].legs[0].duration_in_traffic);
  }
});
