Currently, I am exploring the functionalities of GraphHopper Route Optimization API for solving Vehicle Routing Problems (VRP) with pickups and deliveries. To test it out, I am using an example from . The specific request I am making is as follows:
var vrp = {
"vehicles": [
{
"vehicle_id": "my_vehicle",
"start_address": {
"location_id": "berlin",
"lon": 13.406,
"lat": 52.537
}
}
],
"services": [
{
"id": "hamburg",
"name": "visit_hamburg",
"address": {
"location_id": "hamburg",
"lon": 9.999,
"lat": 53.552
}
},
{
"id": "munich",
"name": "visit_munich",
"address": {
"location_id": "munich",
"lon": 11.57,
"lat": 48.145
}
},
{
"id": "cologne",
"name": "visit_cologne",
"address": {
"location_id": "cologne",
"lon": 6.957,
"lat": 50.936
}
},
{
"id": "frankfurt",
"name": "visit_frankfurt",
"address": {
"location_id": "frankfurt",
"lon": 8.67,
"lat": 50.109
}
}
]
};
$.ajax({
beforeSend: function(xhrObj){
xhrObj.setRequestHeader("Content-Type","application/json");
xhrObj.setRequestHeader("Accept","application/json");
},
type: "POST",
url: 'https://graphhopper.com/api/1/vrp/optimize?key=[...]',
data: vrp,
dataType: "json",
success: function(json){
console.log(json);
}});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>Upon sending the request, I receive the following response: screenshot
I am facing an issue with this setup. Any insights on what the problem could be?
