Cómo realizar una solicitud a la API

Se puede usar un mensaje OptimizeToursRequest para realizar una solicitud OptimizeTours.

Ejemplo: Realiza una solicitud `OptimizeTours`

Las bibliotecas cliente también están disponibles para varios lenguajes de programación populares. Las solicitudes de OptimizeTours también se pueden realizar con REST o gRPC.

Antes de realizar una solicitud, reemplaza los siguientes parámetros por los valores adecuados para tu entorno:

Asegúrate de tener configuradas las credenciales predeterminadas de la aplicación como se describe en Cómo usar OAuth.
Establece PROJECT_NUMBER_OR_ID en el número o el ID de tu proyecto de Cloud.

Go

Realiza una solicitud con la biblioteca cliente de Go:

	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()

Node.js

Primero, solicita una copia del archivo cliente de Node.js a tu representante de Google Maps Platform.

Configura tu archivo package.json con el siguiente fragmento 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"
    }
  }

Realiza una solicitud con la biblioteca cliente de Node.js:
