给定一个链接，我想使用此处的REST API检索相应的道路链接数据。
我已经使用了路由API获取坐标的路链ID(最接近的道路链接是返回，这是我想要的(，但是由于它是路由API，不是实际的道路链接本身。我需要整个道路链接几何形状，我不必指定图块并映射特定数据。
API获取请求：https://route.api.here.com/routing/7.2/calculateroute.json?mode=fastest;car;traffic:enabled&routeAttributes=shape,incidents&departure=now&legAttributes=all&app_id={APP ID}&app_code={APP CODE}&waypoint0=57.69935469580243,11.987510919570923&waypoint1=57.69935469580243,11.987510919570923&linkAttributes=all&jsonAttributes=128&maneuverAttributes=all
产生：

如您所见，结果包含一个链接(好(，但该链接上只有一个点(糟糕(。我环顾四周，特别是在此处建议的流量流API和平台数据扩展API。
您需要的几何信息可以从车队远程信息处理高级数据集中检索。link_fc1 ... 5层的图层数据将为您提供给定地图区域中所有链接ID的链接连接/几何信息。例如，给定路链路ID，您可以获得REF_NODE_NEIGHBOR_LINKS，并且NONREF_NODE_NEIGHBOR_LINKS定义如下：
"REF_NODE_NEIGHBOR_LINKS": "Comma seperated list of LINK_IDs that are connected to this link via the reference node. If a LINK_ID is negative ('-') then this link is connected via it's non reference node.",
"NONREF_NODE_NEIGHBOR_LINKS": "Comma seperated list of LINK_IDs that are connected to this link via the non reference node. If a LINK_ID is negative ('-') then this link is connected via it's non reference node."
