叫車

您可以使用 gRPC 或 REST 從伺服器環境取得車輛。本文件提供這兩種做法的範例。

使用 gRPC 取得快遞車輛

Java

以下範例說明如何使用 Java gRPC 程式庫查詢車輛。

  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

如要使用 REST 從伺服器環境取得車輛，請呼叫 GetVehicle，如下所示：

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}"

如果查詢成功，回應主體會包含車輛實體。
