为什么这条折线画错了？

Question

有人知道为什么这条特定的折线画错了吗？ 通常一切都很好，但是对于这次旅行，我现在不再有想法了！ 测试地点：http://junkvibration.com/test/walk/test.htm

感谢您的帮助！

这个例子我的路点是：

waypoints: [{location:"Lucern",stopover:false},{location:"Paris",stopover:false},
{location:"Madrid",stopover:false},{location:"Granada",stopover:false},
{location:"Barcelona",stopover:false},{location:"Monaco",stopover:false},
{location:"Rom",stopover:false}],
optimizeWaypoints: false,
travelMode: google.maps.DirectionsTravelMode.WALKING };

对我来说，这看起来像是 DirectionsService 中的一个错误。

如果我把所有的航路点都设为 {stopover:true} 那么它就可以了。

function calcRoute() {
  var request = {
    origin: "Bad Aussee",
    destination: "Rottenmann",
    waypoints: [{
      location:"Lucern",
      stopover:true
    },{
      location:"Paris",
      stopover:true
    },{
      location:"Madrid",
      stopover:true
    },{
      location:"Granada",
      stopover:true
    },{
      location:"Barcelona",
      stopover:true
    },{
      location:"Monaco",
      stopover:true
    },{
      location:"Rom",
      stopover:true
    }],
    optimizeWaypoints: false,
    travelMode: google.maps.DirectionsTravelMode.DRIVING
  };

  directionsService.route(request, function(response, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(response);
    } else {
      alert("Directions request failed: "+status);
    }
  });
}

working example - stopover:true

not working (ZERO_RESULTS) - stopover:false, same request as above otherwise

example tries the same request first with stopover:false (fails), then with stopover:true (succeeds)

walking directions (UNKNOWN_ERROR with stopover:true, weird path with stopover:false)

walking directions using multiple requests to the DirectionsService - 更好，但似乎想让我从摩纳哥游到罗马...
