【问题描述】：

我想获得关于我从 HERE Routing API v8 获得的操作的每条指令的纬度和经度。我从 HERE Routing v7 获得了演习，但在 v8 上没有。我尝试了所有的返回值。

【解决方案1】：

截至 2022 年 2 月 2 日，v7 中输出经纬度的位置参数不支持在 v8 中的机动属性下。 Source

【解决方案2】：

这在 V8 布线中是正确的，在机动中存在折线偏移。偏移量是折线的索引，V8 中的所有坐标都以这种方式工作。跨度，动作，它们已经偏移到作为坐标数组的路线形状中。示例：https://demo.routing.ext.here.com/#url=https://router.hereapi.com/v8/routes?apikey=DEFAULT_API_KEY&origin=52.551325,13.351349&destination=52.514255,13.34929&return=polyline,summary,actions,instructions&transportMode=car
