Authentifizierung einrichten
Wenn Sie Clientbibliotheken verwenden, authentifizieren Sie sich mit Standardanmeldedaten für Anwendungen (Application Default Credentials, ADC). Informationen zum Einrichten von ADC finden Sie unter Anmeldedaten für Standardanmeldedaten für Anwendungen bereitstellen. Informationen zur Verwendung von ADC mit Clientbibliotheken finden Sie unter Mit Clientbibliotheken authentifizieren.

Java
Compute Routes-Beispiel:
import com.google.maps.routing.v2.*; import java.io.IOException; import java.util.HashMap; import java.util.Map; public class Main { public static void main(String[] arguments) throws IOException { RoutesSettings routesSettings = RoutesSettings.newBuilder() .setHeaderProvider(() -> { Map<String, String> headers = new HashMap<>(); headers.put("X-Goog-FieldMask", "*"); return headers; }).build(); RoutesClient routesClient = RoutesClient.create(routesSettings); ComputeRoutesResponse response = routesClient.computeRoutes(ComputeRoutesRequest.newBuilder() .setOrigin(Waypoint.newBuilder().setPlaceId("ChIJeRpOeF67j4AR9ydy_PIzPuM").build()) .setDestination(Waypoint.newBuilder().setPlaceId("ChIJG3kh4hq6j4AR_XuFQnV0_t8").build()) .setRoutingPreference(RoutingPreference.TRAFFIC_AWARE) .setTravelMode(RouteTravelMode.DRIVE).build()); System.out.println("Response: " + response.toString()); } }
Route Matrix-Beispiel:
import com.google.api.gax.rpc.ServerStream; import com.google.api.gax.rpc.ServerStreamingCallable; import com.google.maps.routing.v2.*; import java.io.IOException; import java.util.HashMap; import java.util.Map; public class Main { public static void main(String[] arguments) throws IOException { RoutesSettings routesSettings = RoutesSettings.newBuilder() .setHeaderProvider(() -> { Map<String, String> headers = new HashMap<>(); headers.put("X-Goog-FieldMask", "*"); return headers; }).build(); RoutesClient routesClient = RoutesClient.create(routesSettings); ServerStreamingCallable<ComputeRouteMatrixRequest, RouteMatrixElement> computeRouteMatrix = routesClient.computeRouteMatrixCallable(); ServerStream<RouteMatrixElement> stream = computeRouteMatrix.call(ComputeRouteMatrixRequest.newBuilder() .addOrigins(RouteMatrixOrigin.newBuilder() .setWaypoint(Waypoint.newBuilder(). setPlaceId("ChIJeRpOeF67j4AR9ydy_PIzPuM").build())) .addDestinations(RouteMatrixDestination.newBuilder() .setWaypoint(Waypoint.newBuilder().setPlaceId("ChIJG3kh4hq6j4AR_XuFQnV0_t8").build()) .build()).setTravelMode(RouteTravelMode.DRIVE) .build()); for (RouteMatrixElement element : stream) { System.out.println("Response : " + element.toString()); } } }

Compute Routes-Beispiel:
import ( "context" "fmt" "io" "os" routing "cloud.google.com/go/maps/routing/apiv2" "cloud.google.com/go/maps/routing/apiv2/routingpb" "google.golang.org/grpc/metadata" ) func main() { ctx := context.Background() client, err := routing.NewRoutesClient(ctx) if err != nil { fmt.Fprintf(os.Stderr, "error: %v\n", err) os.Exit(1) } computeRoutesReq := routingpb.ComputeRoutesRequest{ Origin: &routingpb.Waypoint{ LocationType: &routingpb.Waypoint_PlaceId{ PlaceId: "ChIJeRpOeF67j4AR9ydy_PIzPuM", }, }, Destination: &routingpb.Waypoint{ LocationType: &routingpb.Waypoint_PlaceId{ PlaceId: "ChIJG3kh4hq6j4AR_XuFQnV0_t8", }, }, RoutingPreference: routingpb.RoutingPreference_TRAFFIC_AWARE, TravelMode: routingpb.RouteTravelMode_DRIVE, } ctx = metadata.AppendToOutgoingContext(ctx, "X-Goog-FieldMask", "*") computeRoutesResponse, err := client.ComputeRoutes(ctx, &computeRoutesReq) if err != nil { fmt.Fprintf(os.Stderr, "error: %v\n", err) os.Exit(1) } fmt.Fprintf(os.Stdout, "response: %v\n", computeRoutesResponse) }

Node.js
Compute Routes-Beispiel:
// Imports the Routing library const { RoutesClient } = require("@googlemaps/routing").v2; const origin = { location: { latLng: { latitude: 37.419734, longitude: -122.0827784, }, }, }; const destination = { location: { latLng: { latitude: 37.41767, longitude: -122.079595, }, }, }; // Instantiates a client const routingClient = new RoutesClient(); async function callComputeRoutes() { const request = { origin, destination, }; // Run request const response = await routingClient.computeRoutes(request, { otherArgs: { headers: { "X-Goog-FieldMask": "routes.duration,routes.distanceMeters,routes.polyline.encodedPolyline", }, }, }); console.log(response); } callComputeRoutes();
Beispiel für Compute Route Matrix:
// Imports the Routing library const { RoutesClient } = require("@googlemaps/routing").v2; const origins = [ { waypoint: { location: { latLng: { latitude: 37.420761, longitude: -122.081356, }, }, }, }, { waypoint: { location: { latLng: { latitude: 37.403184, longitude: -122.097371, }, }, }, }, ]; const destinations = [ { waypoint: { location: { latLng: { latitude: 37.420999, longitude: -122.086894, }, }, }, }, { waypoint: { location: { latLng: { latitude: 37.383047, longitude: -122.044651, }, }, }, }, ]; // Instantiates a client const routingClient = new RoutesClient(); async function callComputeRouteMatrix() { // Construct request const request = { origins, destinations, }; // Run request const stream = await routingClient.computeRouteMatrix(request, { otherArgs: { headers: { "X-Goog-FieldMask": "*", }, }, }); stream.on("data", (response) => { console.log(response); }); stream.on("error", (err) => { throw err; }); stream.on("end", () => { /* API call completed */ }); } callComputeRouteMatrix();
