Bibliotecas cliente de GAPI

En el caso de la comunicación de servidor a servidor (de confianza), te recomendamos que uses las bibliotecas cliente de GAPI específicas del lenguaje para obtener una mejor experiencia que el desarrollo a través de REST o gRPC sin procesar. Los archivos protobuf en los que se basan estos clientes están disponibles de forma pública en https://github.com/googleapis/googleapis/tree/master/google/maps/fleetengine/v1.

Si las bibliotecas no existen en el lenguaje de tu aplicación, te recomendamos usar gRPC o los extremos REST de Fleet Engine.

NOTA: Las bibliotecas GAPIC están diseñadas para ejecutarse en entornos de confianza (servidor). Los JWT no son necesarios. Usar las credenciales predeterminadas de la aplicación junto con la función de ondemandAdmin adecuada

Java

Las bibliotecas de Java se publican en google.maps.fleetengine.v1.

Puedes usar la biblioteca de autenticación de Fleet Engine para Java a fin de crear tokens web JSON firmados dentro del entorno de Java.

Puedes ver ejemplos de Java para interactuar con la API de Fleet Engine en la página Comienza a usar Fleet Engine.

Node.js o TypeScript

npm

Puedes especificar la URL de la biblioteca en la sección dependencies de package.json:

{
  "dependencies": {
    "@googlemaps/fleetengine": "https://storage.googleapis.com/fleetengine-gapic/dist/latest_release/maps-fleetengine-v1-nodejs.tar.gz",
