יצירת רכב מסירה למשימות מתוזמנות

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

כדי ליצור רכב מסביבת שרת, שולחים קריאה ל-HTTP REST אל CreateDeliveryVehicle:

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

גוף ה-POST מייצג את הישות DeliveryVehicle שרוצים ליצור. אפשר לציין את השדות האופציונליים הבאים:

• 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

כדי ליצור רכב בלי להגדיר שדות, משאירים את גוף הבקשה מסוג POST ריק. לאחר מכן, הרכב החדש שנוצר מחלץ מזהה רכב מהפרמטר deliveryVehicleId בכתובת ה-URL של ה-POST.

דוגמה:

  # 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}"
