Google Maps API V3 - 如何通过任意路点获得最佳往返路线

Question

关于Google Maps V3 API路线点有许多问题，但没有解决如何从一组任意路点获得最佳往返路线的问题。基本上，衡量点的顺序应该由最佳路径决定，而不一定由馈入系统的顺序决定。有人知道这是否可能吗？

Answer 1

V3 API中有一个“优化”选项。你试过了吗？

optimizeWaypoints

从 https://developers.google.com/maps/documentation/javascript/reference

If set to true, the DirectionService will attempt to re-order the supplied 
intermediate waypoints to minimize overall cost of the route. If waypoints 
are optimized, inspect DirectionsRoute.waypoint_order in the response to 
determine the new ordering. 

optimizeWaypoints (optional) specifies that the route using the supplied 
waypoints may be optimized to provide the shortest possible route.
