GraphHopper 车辆=汽车可以工作，但步行或自行车不能工作 [英] GraphHopper vehicle=car works but foot or bike don't work

问题描述

我对 GraphHopper 路由引擎稳定版 0.5 有疑问

I have an issue with the GraphHopper routing engine stable version 0.5

我可以在使用 vehicle=car 时获取路线，但使用 bike 和 foot 会失败.

I can get directions when using the vehicle=car, but this fails with bike and foot.

这里是在 GraphHopper 地图上步行大约 3 分钟的示例:

这会在地图上产生一个结果，这很棒.

This yields a result on the map, which is great.

我在本地运行时使用了完全相同坐标，获取JSON数据如下:

I have used the exact same coordinates when running this locally, to obtain the JSON data as follows:

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:

This yields no result, but instead returns the following response:

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

请注意，将 vehicle 更改为 car 会产生结果！如何解决这个问题??

Note that changing the vehicle to car yields a result! How can this be fixed??

为了完整起见，这里是带有 vehicle=car 的示例请求和响应

For completeness sake, here is the sample request and response with vehicle=car

推荐答案

你必须将它包含在你的 config.properties 中

You have to include it in your config.properties

graph.flagEncoders=car,foot,bike

顺便说一句:我已经编辑了您的帖子.要阐明 GraphHopper 路由引擎和 GraphHopper Directions API 之间的区别，请参阅此处

BTW: I've edited your post. To clarify the difference between the GraphHopper routing engine and the GraphHopper Directions API see here
