GraphHopper vehicle =汽车可行但脚或自行车不起作用

Question

我有一个GraphHopper路由引擎稳定版本0.5的问题

我可以在使用时获得指示vehicle=car,但这会因自行车和脚而失败.

以下是 GraphHopper地图上大约3分钟步行的示例:

这会在地图上产生结果,这很棒.

我在本地运行时使用了完全相同的坐标,以获取JSON数据,如下所示:

http://localhost:8989/routes?point=-33.916567%2C18.417914&point=-33.917584%2C18.418935&locale=en-US&vehicle=foot

这不会产生任何结果,而是返回以下响应:

{
  "message": "Vehicle not supported: foot",
  "hints": [{
    "message": "Vehicle not supported: foot",
    "details": "java.lang.IllegalArgumentException"
  }]
}

请注意,将车辆更改为汽车会产生结果!怎么能修好？

为了完整起见,这里是使用vehicle = car的样本请求和响应

您必须将它包含在config.properties中

graph.flagEncoders=car,foot,bike

顺便说一句:我已经编辑了你的帖子.为了阐明GraphHopper路由引擎和GraphHopper Directions API之间的区别,请参见此处
