Buat Permintaan API

Pesan OptimizeToursRequest dapat digunakan untuk membuat permintaan OptimizeTours.

Contoh: Membuat Permintaan `OptimizeTours`

Permintaan OptimizeTours dapat dibuat menggunakan REST atau gRPC. Library klien juga tersedia untuk beberapa bahasa pemrograman populer. Contoh ini menggunakan kombinasi alat command line dan library klien untuk membuat permintaan.

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

Pastikan Anda telah mengonfigurasi Kredensial Default Aplikasi seperti yang dijelaskan dalam Menggunakan OAuth.
Tetapkan PROJECT_NUMBER_OR_ID ke nomor atau ID project Cloud 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)
}
optimize_tours.go

public class OptimizeTours {
  public static void main(String[] args) throws Exception {
    System.out.println(optimizeTours());
  }

public static OptimizeToursResponse optimizeTours() throws Exception {
    try (RouteOptimizationClient routeOptimizationClient = RouteOptimizationClient.create()) {
      OptimizeToursRequest request =
          OptimizeToursRequest.newBuilder()
              .setParent("projects/PROJECT_NUMBER_OR_ID")
              .setModel(
                  ShipmentModel.newBuilder()
                      .addShipments(
                          Shipment.newBuilder()
                              .addPickups(

                      .addVehicles(
                          Vehicle.newBuilder()
                              .setStartLocation(

              .build();
      return routeOptimizationClient.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

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": "2024-02-13T00:00:00.000Z",
      "global_end_time": "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();
