The routing service used by Waypoint does not find a solution for a given request if specifying the 'Use Preferred Truck Routes' parameter in attributeParameterValues.

解决办法

For this test case, the routing service can find the route if the "Use Preffered Truck Routes" restriction attribute is not specified as part of the travelMode parameter. Send the modified parameters from below as a POST request again, and the route is returned.

1. Generate an ArcGIS Online token (POST request) with the following parameters below:

• Request URL: https://www.arcgis.com/sharing/rest/generateToken
  • username:-----USERNAME HERE-----
  • password:-----PASSWORD HERE-----
  • f:pjson
  • request:getToken
  • client:referer
  • referer:https://route-ls.arcgis.com/

2. Use the parameters below to send the POST request. Copy-pasting the generated token from the previous step into the token parameter is applicable.

• Request URL: https://route-ls.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route_World/solve
  • directionsLengthUnits:esriNAUKilometers
  • f:json
  • ignoreInvalidLocations:true
  • returnRoutes:false
