购买车辆

您可以使用 gRPC 或 REST 从服务器环境中获取车辆。本文档提供了这二者的示例。

使用 gRPC 获取配送车辆

Java

以下示例展示了如何使用 Java gRPC 库查找车辆。

  static final String PROJECT_ID = "my-delivery-co-gcp-project";
  static final String VEHICLE_ID = "vehicle-8241890";

  DeliveryServiceBlockingStub deliveryService =
    DeliveryServiceGrpc.newBlockingStub(channel);

  // Vehicle request
  String name = "providers/" + PROJECT_ID + "/deliveryVehicles/" + VEHICLE_ID;
  GetDeliveryVehicleRequest getVehicleRequest = GetDeliveryVehicleRequest.newBuilder()  // No need for the header
      .setName(name)
      .build();

  try {
    DeliveryVehicle vehicle = deliveryService.getDeliveryVehicle(getVehicleRequest);
  } catch (StatusRuntimeException e) {
    Status s = e.getStatus();
    switch (s.getCode()) {
       case NOT_FOUND:
         break;
       case PERMISSION_DENIED:
         break;
    }
    return;
  }

REST

如需使用 REST 从服务器环境中获取车辆，请按如下方式调用 GetVehicle：

GET https://fleetengine.googleapis.com/v1/providers/<project_id>/deliveryVehicles/<vehicleId>

  # Set JWT, PROJECT_ID, and VEHICLE_ID in the local environment
  curl -H "Authorization: Bearer ${JWT}" \
    "https://fleetengine.googleapis.com/v1/providers/${PROJECT_ID}/deliveryVehicles/${VEHICLE_ID}"

如果查找成功，响应正文将包含一个车辆实体。
