Esempi di librerie client Navigation Connect

Questa pagina fornisce esempi di come utilizzare le librerie client di Navigation Connect per chiamare i seguenti metodi:

Installazione delle librerie client

Per le istruzioni di installazione, consulta Librerie client di Navigation Connect.

Autenticazione

Quando utilizzi le librerie client, usi Credenziali predefinite dell'applicazione (ADC) per l'autenticazione. Per informazioni sulla configurazione di ADC, consulta Fornire credenziali per Credenziali predefinite dell'applicazione. Per informazioni sull'utilizzo di ADC con le librerie client, consulta Autenticazione mediante librerie client.

Gli esempi riportati in questa pagina utilizzano Credenziali predefinite dell'applicazione.

Creazione di un viaggio (CreateTrip)

I seguenti esempi mostrano come chiamare CreateTrip per inizializzare un viaggio e ottenere un token di viaggio autenticato.

Python

from google.maps import navconnect_v1

def create_trip(project_id: str, trip_id: str, android_app_id: str, ios_app_id: str):
    # Initialize the client with ADC
    client = navconnect_v1.NavConnectServiceClient()

    # Construct the trip request
    request = navconnect_v1.CreateTripRequest(
        parent=f"projects/{project_id}",
        trip_id=trip_id,
        trip=navconnect_v1.Trip(
            android_app_id=android_app_id,
            ios_app_id=ios_app_id,
            config=navconnect_v1.TripConfig(
                enable_pubsub=True,
            ),
        ),
    )

    try:
        response = client.create_trip(request=request)

    except Exception as e:
        print(f"Error creating trip: {e}")

Recupera dati sul percorso (GetTrip)

I seguenti esempi mostrano come chiamare GetTrip per recuperare lo stato in tempo reale, la telemetria e i dati del percorso rimanenti per un viaggio.

Python

    # Initialize the client with ADC
    client = navconnect_v1.NavConnectServiceClient()

    request = navconnect_v1.GetTripRequest(
        name=f"projects/{project_id}/trips/{trip_id}",
        route_polyline_format=navconnect_v1.GetTripRequest.RoutePolylineFormat.GEO_JSON,
    )

    try:
        response = client.get_trip(request=request)
        print(f"Trip Status: {response.state}")
