不在 Amazon Location 中道路上的位置

使用 CalculateRoute或 時CalculateRouteMatrix，如果您指定不在 Amazon Location 道路上的出發點、目的地或航點位置，則會將位置移至附近的道路。

下列CalculateRoute請求會指定不在道路上的出發位置和目的地位置：

POST /routes/v0/calculators/ExampleCalculator/calculate/route
Content-type: application/json
{
   "DeparturePosition": [-123.128014, 49.298472],
   "DestinationPosition": [-123.134701, 49. 294315]
}

產生的回應會傳回卡在附近道路的位置：
