如何使用红宝石获得两个坐标之间的汽车路线? [英] How get car route between two coordinates using ruby?

问题描述

我正在使用Google地图和汽车路线开发Rails应用.

I'm developing rails app with google maps and car routes.

我有汽车路线的起点和终点-两个坐标.如何获得完整的汽车路线(通过街道的汽车坐标数组)?我可以使用gmaps4rails和geocoder进行操作吗?

I have a start and finish points for car route - two coordinates. How can I get a full car route (array of coordinates for car through streets)? Can I do it using gmaps4rails and geocoder?

类似这样的东西:

start_point = [41,2423; 45,323452]
end_point   = [42,2423; 42,323452]

full_route = some_method_for_calculate_route( start_point, end_point )

#paint line on map from array of points
paint_line( full_route )

请帮助， 谢谢:)

推荐答案

如果要在客户端执行此操作，则可以使用在这里放屁.

If you want to do it client side, you have a plunkr here.

它受到此处的Google文档的启发.

基本上是与Google图书馆互动的一种方式

Basically its a way to interact with google libraries

  var handler = Gmaps.build('Google');
  handler.buildMap({ internal: {id: 'map'}}, function(){

    var start_point = [43.2423, 5.323452];
    var end_point   = [44.2423, 5.323452];

    var directionsService = new google.maps.DirectionsService();
    var directionsDisplay = new google.maps.DirectionsRenderer();

    directionsDisplay.setMap(handler.getMap());
    var request = {
      origin:      new google.maps.LatLng(start_point[0], start_point[1]),
      destination: new google.maps.LatLng(end_point[0], end_point[1]),
      travelMode:  google.maps.TravelMode.DRIVING
    };

    directionsService.route(request, function(response, status) {
      if (status === google.maps.DirectionsStatus.OK) {
        directionsDisplay.setDirections(response);
      }
    });
  });
