Here maps API routing api “linkid prefix not valid”

Question

I use HERE Maps Routing REST API 7.2. When I try to execute "getlinkinfo", I get the message "linkid prefix not valid".

Here is example of request (use your token and app id):

https://route.api.here.com/routing/7.2/getlinkinfo.json?linkids=1048943660&linkattributes=speedLimit,functionalClass,speedCategory&token=my_token&app_id=my_app_id

Answer 1

您应该为 LinkIds 添加“+”或“-”，并且 linkAttributes 不支持速度类别，而且 getLinkInfo 是 Beta 端点，对于速度限制，您可以尝试使用平台数据扩展 API，route.api.here。 com/routing/7.2/…
