Buat Permintaan API

Pesan OptimizeToursRequest dapat digunakan untuk membuat permintaan OptimizeTours.

Contoh: Membuat Permintaan OptimizeTours

Library klien juga tersedia untuk beberapa bahasa pemrograman populer. Permintaan OptimizeTours juga dapat dibuat menggunakan REST atau gRPC.

Sebelum membuat permintaan, ganti parameter berikut dengan nilai yang sesuai untuk lingkungan Anda:

Go

Buat permintaan menggunakan library klien 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)
}

    // Optional: method calls that last tens of minutes may be interrupted
    // without enabling a short keep-alive interval.

    RouteOptimizationClient client = RouteOptimizationClient.create(clientSettings);
    OptimizeToursRequest request =
        OptimizeToursRequest.newBuilder()
            .setParent("projects/" + projectId)
            .setModel(
                ShipmentModel.newBuilder()
                    .addShipments(
                        Shipment.newBuilder()

            .build();
    return client.optimizeTours(request);
  }

Python

Klien Python tersedia di PyPI.

pip install google-maps-routeoptimization

Buat permintaan menggunakan library klien 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,

          },
          "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

Pertama, minta salinan arsip klien Node.js dari perwakilan Google Maps Platform Anda.

Konfigurasikan file package.json menggunakan cuplikan JSON berikut:

  {
    "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"
    }
  }

Buat permintaan menggunakan library klien 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();
