问如何将latlong数据转换为路点值/ calculateRoute()？(此处为API/ Matrix API)

  function geocode(platform, street2, city2) 
  {
    var street3 = street2;
    var city3 = city2; 

    var geocoder = platform.getGeocodingService(),
    parameters = {
      searchtext: street3 + city3 ,
      gen: '9'};

   geocoder.geocode(parameters,
    function (result) {
       var lat = result.Response.View[0].Result[0].Location.DisplayPosition.Latitude;
       var long = result.Response.View[0].Result[0].Location.DisplayPosition.Longitude;
       calculateRoute(platform, lat, long);
    }, function (error) {
      console.log("Retrieving Latitude and Longitude failed! Refresh the page and try again.");
    });



    function calculateRoute(platform,latitude,longitude) 
  {
    var x = latitude;
    var y = longitude;
    var router = platform.getRoutingService(),
    parameters = {
      waypoint0: x + "," + y,
      waypoint1: '49.998700,8.249140',
      mode: 'fastest;car;traffic:enabled',
      departure: 'now'};

    router.calculateRoute(parameters,
    function (result) {
      console.log(result.response.route[0].summary.distance);
    }, function (error) {
      console.log("error");
    });
  }
