Google Maps API V3 - 如何通过任意航点获得最佳往返路线

Question

关于Google Maps V3 API航点的问题很多，但没有一个问题涉及如何从一组任意航路点获得最佳往返航线。基本上，称重点的顺序应由最佳路径确定，并且不一定由送入系统的顺序决定。有人知道这是否可能吗？

Answer 1

V3 API中有一个“优化”选项。你试过吗？

optimizeWaypoints

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.
