您可以使用 gRPC 或 REST 从服务器环境获取车辆。本文档提供了这两种方法的示例。
使用 gRPC 获取配送车辆
Java
以下示例展示了如何使用 Java gRPC 库查询车辆。
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,响应正文将包含车辆实体。
