关于 Google Maps V3 API 航点有很多问题，但没有一个可以解决如何从一组任意航点获得最佳往返路线。基本上，称重点的顺序应由最佳路径决定，不一定由输入系统的顺序决定。有人知道这是否可能吗？

V3 API 中有一个“优化”选项。你试过了吗？
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.
