إنشاء مركبة توصيل للمهام المُجدوَلة

Java

  static final String PROJECT_ID = "my-delivery-co-gcp-project";
  static final String VEHICLE_ID = "vehicle-8241890"; // Avoid auto-incrementing IDs.

  DeliveryServiceBlockingStub deliveryService =
    DeliveryServiceGrpc.newBlockingStub(channel);

  // Vehicle settings
  String parent = "providers/" + PROJECT_ID;
  DeliveryVehicle vehicle = DeliveryVehicle.newBuilder()
    .addAttributes(DeliveryVehicleAttribute.newBuilder()
      .setKey("route_number").setValue("1"))  // Opaque to the Fleet Engine
    .build();

  // Vehicle request
  CreateDeliveryVehicleRequest createVehicleRequest =
    CreateDeliveryVehicleRequest.newBuilder()  // No need for the header
        .setParent(parent)
        .setDeliveryVehicleId(VEHICLE_ID)     // Vehicle ID assigned by the Provider
        .setDeliveryVehicle(vehicle)
        .build();

  // Error handling
  // If Fleet Engine does not have vehicle with that ID and the credentials of the
  // requestor pass, the service creates the vehicle successfully.

  try {
    DeliveryVehicle createdVehicle =
      deliveryService.createDeliveryVehicle(createVehicleRequest);
  } catch (StatusRuntimeException e) {
    Status s = e.getStatus();
    switch (s.getCode()) {
       case ALREADY_EXISTS:
         break;
       case PERMISSION_DENIED:
         break;
    }
    return;
  }

REST

لإنشاء مركبة من بيئة خادم، يمكنك إجراء طلب HTTP REST إلى CreateDeliveryVehicle:

POST https://fleetengine.googleapis.com/v1/providers/<project_id>/deliveryVehicles?deliveryVehicleId=<id>

يمثّل نص POST كيان DeliveryVehicle الذي سيتم إنشاؤه. يمكنك تحديد الحقول الاختيارية التالية:

• attributes
• lastLocation
• type

  # Set $JWT, $PROJECT_ID, and $VEHICLE_ID in the local
  # environment
  curl -X POST "https://fleetengine.googleapis.com/v1/providers/${PROJECT_ID}/deliveryVehicles?deliveryVehicleId=${VEHICLE_ID}" \
    -H "Content-type: application/json" \
    -H "Authorization: Bearer ${JWT}" \
  --data-binary @- << EOM
  {
    "attributes": [{"key": "model", "value": "sedan"}],
    "lastLocation": {"location": {"latitude": 12.1, "longitude": 14.5}}
  }
  EOM

لإنشاء مركبة بدون ضبط أي حقول، اترك نص طلب POST فارغًا. بعد ذلك، تستخرج المركبة التي تم إنشاؤها حديثًا معرّف مركبة من المَعلمة deliveryVehicleId في عنوان URL لطلب POST.

مثال:

  # Set $JWT, $PROJECT_ID, and $VEHICLE_ID in the local
  # environment
  curl -X POST "https://fleetengine.googleapis.com/v1/providers/${PROJECT_ID}/deliveryVehicles?deliveryVehicleId=${VEHICLE_ID}" \
    -H "Content-type: application/json" \
    -H "Authorization: Bearer ${JWT}"
