pode ser usada para fazer uma solicitação
OptimizeTours
.
Exemplo: fazer uma solicitação OptimizeTours
As bibliotecas de cliente também estão disponíveis para várias linguagens de programação conhecidas.
As solicitações OptimizeTours
também podem ser feitas usando REST ou gRPC.
Antes de fazer uma solicitação, substitua os seguintes parâmetros pelos valores adequados para seu ambiente:
- Verifique se você configurou as Application Default Credentials conforme descrito em Usar o OAuth.
Defina PROJECT_NUMBER_OR_ID como o número ou ID do projeto do Cloud.
Go
Faça uma solicitação usando a biblioteca de cliente do Go:
import ( "context" "fmt" routeoptimization "cloud.google.com/go/maps/routeoptimization/apiv1" "google.golang.org/genproto/googleapis/type/latlng" rpb "cloud.google.com/go/maps/routeoptimization/apiv1/routeoptimizationpb" ) func optimizeTours(projectID string) (*rpb.OptimizeToursResponse, error) { ctx := context.Background() c, err := routeoptimization.NewClient(ctx) if err != nil { return nil, fmt.Errorf("routeoptimization client: %w", err) } defer c.Close() // See https://pkg.go.dev/cloud.google.com/go/maps/routeoptimization/apiv1/routeoptimizationpb#OptimizeToursRequest. req := &rpb.OptimizeToursRequest{ Parent: "projects/" + projectID, Model: &rpb.ShipmentModel{ Shipments: []*rpb.Shipment{ &rpb.Shipment{ Deliveries: []*rpb.Shipment_VisitRequest{ {ArrivalLocation: &latlng.LatLng{Latitude: 48.880942, Longitude: 2.323866}}, }, }, }, Vehicles: []*rpb.Vehicle{ { StartLocation: &latlng.LatLng{Latitude: 48.863102, Longitude: 2.341204}, EndLocation: &latlng.LatLng{Latitude: 48.86311, Longitude: 2.341205}, }, }, }, } return c.OptimizeTours(ctx, req) }
Java
Faça uma solicitação usando a biblioteca de cliente Java:
import com.google.maps.routeoptimization.v1.OptimizeToursRequest; import com.google.maps.routeoptimization.v1.OptimizeToursResponse; import com.google.maps.routeoptimization.v1.RouteOptimizationClient; import com.google.maps.routeoptimization.v1.RouteOptimizationSettings; import com.google.maps.routeoptimization.v1.Shipment; import com.google.maps.routeoptimization.v1.Shipment.VisitRequest; import com.google.maps.routeoptimization.v1.ShipmentModel; import com.google.maps.routeoptimization.v1.Vehicle; import com.google.type.LatLng; import java.time.Duration; public class OptimizeTours { public static OptimizeToursResponse optimizeTours(String projectId) throws Exception { // Optional: method calls that last tens of minutes may be interrupted // without enabling a short keep-alive interval. RouteOptimizationSettings clientSettings = RouteOptimizationSettings .newBuilder() .setTransportChannelProvider(RouteOptimizationSettings .defaultGrpcTransportProviderBuilder() .setKeepAliveTimeDuration(Duration.ofSeconds(30)) .build()).build(); RouteOptimizationClient client = RouteOptimizationClient.create(clientSettings); OptimizeToursRequest request = OptimizeToursRequest.newBuilder() .setParent("projects/" + projectId) .setModel( ShipmentModel.newBuilder() .addShipments( Shipment.newBuilder() .addPickups( VisitRequest.newBuilder() .setArrivalLocation( LatLng.newBuilder().setLatitude(48.8).setLongitude(2.4)))) .addVehicles( Vehicle.newBuilder() .setStartLocation( LatLng.newBuilder().setLatitude(48.9).setLongitude(2.5)))) .build(); return client.optimizeTours(request); } }
Python
O cliente Python está disponível no PyPI (link em inglês).
pip install google-maps-routeoptimization
Faça uma solicitação usando a biblioteca de cliente Python:
from google.maps import routeoptimization_v1 as ro from datetime import datetime client = ro.RouteOptimizationClient() request = ro.OptimizeToursRequest( parent="projects/PROJECT_NUMBER_OR_ID", model={ "shipments": [ { "pickups": [ { "arrival_location": { "latitude": 37.738818, "longitude": -122.4161 } } ], "deliveries": [ { "arrival_location": { "latitude": 37.79581, "longitude": -122.4218856 } } ] } ], "vehicles": [ { "start_location": { "latitude": 37.738818, "longitude": -122.4161 }, "end_location": { "latitude": 37.738818, "longitude": -122.4161 }, "cost_per_kilometer": 1.0 } ], "global_start_time": datetime.fromisoformat("2024-02-13T00:00:00.000Z"), "global_end_time": datetime.fromisoformat("2024-02-14T06:00:00.000Z") } ) response = client.optimize_tours(request=request) print(response)
Node.js
Primeiro, solicite uma cópia do arquivo do cliente do Node.js ao seu representante da Plataforma Google Maps.
Configure o arquivo package.json
usando o seguinte snippet JSON:
{
"name": "route-optimization-example",
"version": "1.0.0",
"description": "A RouteOptimization example.",
"main": "main.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"dependencies": {
"@googlemaps/routeoptimization": "^0.1.0"
}
}
Faça uma solicitação usando a biblioteca de cliente Node.js:
'use strict'; const {RouteOptimizationClient} = require('@googlemaps/routeoptimization').v1; const routeoptimizationClient = new RouteOptimizationClient(); async function callOptimizeTours() { const response = await routeoptimizationClient.optimizeTours({ "parent": "projects/PROJECT_NUMBER_OR_ID", "model": { "shipments": [ { "pickups": [ { "arrivalLocation": { "latitude": 37.73881799999999, "longitude": -122.4161 } } ], "deliveries": [ { "arrivalLocation": { "latitude": 37.79581, "longitude": -122.4218856 } } ] } ], "vehicles": [ { "startLocation": { "latitude": 37.73881799999999, "longitude": -122.4161 }, "endLocation": { "latitude": 37.73881799999999, "longitude": -122.4161 }, "costPerKilometer": 1.0 } ], "globalStartTime": "2024-02-13T00:00:00.000Z", "globalEndTime": "2024-02-14T06:00:00.000Z" } }); console.log(JSON.stringify(response)); } callOptimizeTours();
REST
O comando a seguir envia uma solicitação OptimizeTours
para a API Route Optimization e recebe uma resposta de forma síncrona.
curl -X POST 'https://routeoptimization.googleapis.com/v1/projects/PROJECT_NUMBER_OR_ID:optimizeTours' \ -H "Content-Type: application/json" \ -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \ --data @- << EOM { "model": { "shipments": [ { "pickups": [ { "arrivalLocation": { "latitude": 37.73881799999999, "longitude": -122.4161 } } ], "deliveries": [ { "arrivalLocation": { "latitude": 37.79581, "longitude": -122.4218856 } } ] } ], "vehicles": [ { "startLocation": { "latitude": 37.73881799999999, "longitude": -122.4161 }, "endLocation": { "latitude": 37.73881799999999, "longitude": -122.4161 }, "costPerKilometer": 1.0 } ], "globalStartTime": "2024-02-13T00:00:00.000Z", "globalEndTime": "2024-02-14T06:00:00.000Z" } } EOM
Quando a solicitação for concluída, você vai receber uma mensagem de resposta.
