Library Klien GAPI

Untuk komunikasi server ke server (tepercaya), sebaiknya gunakan library klien GAPI khusus bahasa untuk pengalaman yang lebih baik daripada mengembangkan melalui REST atau gRPC mentah. File protobuf yang menjadi dasar klien ini tersedia secara publik di https://github.com/googleapis/googleapis/tree/master/google/maps/fleetengine/delivery/v1.

Jika library tidak ada dalam bahasa aplikasi Anda, sebaiknya gunakan endpoint gRPC atau REST Flet Engine.

CATATAN: Library GAPIC dimaksudkan untuk berjalan di lingkungan tepercaya (server). JWT tidak diperlukan. Gunakan Kredensial Default Aplikasi beserta peran deliveryAdmin yang sesuai.

Java

Library Java dipublikasikan di google.maps.fleetengine.delivery.v1.

Anda dapat menggunakan Library Authentication Engine Auth untuk Java untuk membuat token web JSON yang ditandatangani dalam lingkungan Java.

Anda dapat melihat contoh Java untuk berinteraksi dengan Fleet Engine API di halaman Getting started with Fleet Engine.

Node.js / TypeScript

// CREATE A JWT FOR AUTHENTICATION
const HOWLONG = 55 * 60;          // 55 minutes, cannot be more than 60 minutes

  google.options({auth: authClient});

  const now = Math.round(Date.now() / 1000);
  const iat = now - 300;

  const request = {

              iat: iat,
              exp: exp,
              authorization: claims

// MAKE A REQUEST
