Exemplos da biblioteca de cliente do Navigation Connect

Esta página fornece exemplos de como usar as bibliotecas de cliente do Navigation Connect para chamar os seguintes métodos:

Instalar as bibliotecas de cliente

Para instruções de instalação, consulte Bibliotecas de cliente do Navigation Connect.

Autenticação

Com as bibliotecas de cliente, você usa Application Default Credentials (ADC) para autenticação. Para acessar informações sobre como configurar o ADC, consulte Fornecer credenciais para o Application Default Credentials. Para informações sobre como usar o ADC com bibliotecas de cliente, consulte Autenticar usando bibliotecas de cliente.

Os exemplos nesta página usam o Application Default Credentials.

Criar uma viagem (CreateTrip)

Os exemplos a seguir mostram como chamar CreateTrip para inicializar uma viagem e receber um token de viagem autenticado.

Python

Recuperar dados de viagem (GetTrip)

Os exemplos a seguir mostram como chamar GetTrip para recuperar o status em tempo real, a telemetria e os dados de rota restantes de uma viagem.

Python
