过渡多段线和路线令牌

此方案使用路线优化 API 生成包含路线多段线的路线令牌。

在 OptimizeToursRequest 消息中，将 populateTransitionPolylines（REST、gRPC）设置为在 OptimizeToursResponse 中为 ShipmentRoute 的转换生成 routePolyline（REST、gRPC）和 routeToken（REST、gRPC）字段。

使用来自 OptimizeTourResponse 的路线令牌在 Navigation SDK 中启动导航会话。导航会话会尝试按照 Route Optimization API 返回的路线行驶。由于道路状况是动态变化的，因此使用给定令牌生成的路线可能与原始路线不同。虽然路线令牌不会过期，但我们建议您在生成令牌后尽快使用路线令牌，以尽可能使实际路线接近规划路线。

使用 Navigator.setDestinations 方法将由 Route Optimization API 生成的路线令牌传递给 Navigation SDK 时，您必须指定与 ShipmentRoute 过渡的结束位置相符的单个目的地。

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。
