我在某些请求中遇到了waypoint_order的问题，它与腿的最终位置匹配，有时则不匹配。以下是我如何发送请求以及航点和航段。
var request = {
origin: start,
destination: end,
waypoints: waypts,
optimizeWaypoints: true,
travelMode: google.maps.DirectionsTravelMode.DRIVING,
unitSystem: google.maps.UnitSystem.IMPERIAL
};
传递航点。
waypt [0] 1450 West Jackson Street Ozark密苏里州----订单[0] 3
waypt [1] 2825 S Glenstone Ave Springfield密苏里州----订单[1] 1
waypt [2] 404 West South Street Nixa Missouri ----订单[2] 0
waypt [3] 500 West Chestnut Expressway斯普林菲尔德密苏里州----订单[3] 4
waypt [4] 715 W. Mt. Vernon Nixa Missouri ----订单[4] 2
航点顺序：3,1,0,4,2

有人知道为什么result.routes [0] .waypoint_order中的waypoint_order会关闭吗？
