Fazer uma solicitação de API

Uma mensagem OptimizeToursRequest 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:

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();
