openrouteservice 2.2.2

基本示例

importopenrouteservicecoords=((8.34234,48.23424),(8.34423,48.26424))client=openrouteservice.Client(key='')# Specify your personal API keyroutes=client.directions(coords)print(routes)

为了方便起见，所有执行请求的模块方法都包装在client类中。这个有 缺点是，IDE不能自动显示 不同的方法。还有很多！

保留IDE的智能功能，稍微详细一点的替代方案是

importopenrouteservicefromopenrouteservice.directionsimportdirectionscoords=((8.34234,48.23424),(8.34423,48.26424))client=openrouteservice.Client(key='')# Specify your personal API keyroutes=directions(client,coords)# Now it shows you all arguments for .directions

优化路线

如果你想在一个简单的Traveling Salesman Problem中优化多个航路点的顺序， 您可以传递一个optimize_waypoints参数：

importopenrouteservicecoords=((8.34234,48.23424),(8.34423,48.26424),(8.34523,48.24424),(8.41423,48.21424))client=openrouteservice.Client(key='')# Specify your personal API keyroutes=client.directions(coords,profile='cycling-regular',optimize_waypoints=True)print(routes)

解码多段线

默认情况下，方向api返回encoded polylines。 要解码为dict，这是一个geojson几何体对象，只需执行

importopenrouteservicefromopenrouteserviceimportconvertcoords=((8.34234,48.23424),(8.34423,48.26424))client=openrouteservice.Client(key='')# Specify your personal API key# decode_polyline needs the geometry onlygeometry=client.directions(coords)['routes'][0]['geometry']decoded=convert.decode_polyline(geometry)print(decoded)

干运行

尽管查询创建中的错误应该得到很好的处理，但是您可以进行一次试运行来打印请求及其参数：

importopenrouteservicecoords=((8.34234,48.23424),(8.34423,48.26424))client=openrouteservice.Client()client.directions(coords,dry_run='true')

本地ORS实例

如果您托管自己的ORS实例，则可以更改base_url参数以适合您自己的实例：

importopenrouteservicecoords=((8.34234,48.23424),(8.34423,48.26424))# key can be omitted for local hostclient=openrouteservice.Client(base_url='http://localhost/ors')# Only works if you didn't change the ORS endpoints manuallyroutes=client.directions(coords)# If you did change the ORS endpoints for some reason# you'll have to pass url and required parameters explicitly:routes=client.request(url='/new_url',post_json={'coordinates':coords,'profile':'driving-car','format':'geojson'})
