在此场景中，系统使用 Route Optimization API 生成包含路线多段线的路线令牌。
在 OptimizeToursRequest 消息中，设置 populateTransitionPolylines（REST、gRPC），以便在 OptimizeToursResponse 中的 ShipmentRoute 的转换中生成 routePolyline（REST、gRPC）和 routeToken（REST、gRPC）字段。
请参阅设置为 populateTransitionPolylines=true 的请求示例

使用来自 OptimizeTourResponse 的路线令牌在 Navigation SDK 中启动导航会话。导航会话会尝试遵循 Route Optimization API 返回的路线。由于道路状况动态变化，使用给定令牌生成的路线可能会与原始路线不同。虽然路线令牌不会过期，但我们建议您在生成路线令牌后尽快使用该令牌，以最大限度地缩短实际路线与计划路线之间的距离。
使用 Navigator.setDestinations 方法将 Route Optimization API 生成的路线令牌传递给 Navigation SDK 时，您必须指定与 ShipmentRoute 转换的结束位置匹配的单个目的地。
如需详细了解路线令牌，请参阅 Android 版 Navigation SDK 和 iOS 版 Navigation SDK 的“规划路线”文档。
如需详细了解路线多段线编码，请参阅多段线。
