批次建立工作

本文說明如何在伺服器環境中建立一批工作。使用 gRPC 或 REST如要進一步瞭解如何建立工作，請參閱：

用於批次建立工作的工作欄位

批次建立工作時，requests 中的每個 CreateTasksRequest 元素必須傳遞與單一工作 CreateTask 要求相同的驗證規則。但 parent 和 header 欄位為選填欄位。如果設定此屬性，這兩者必須與頂層項目對應的欄位相同 BatchCreateTasksRequest。

詳情請參閱 BatchCreateTasks 的 API 參考說明文件適用於 gRPC 或 REST。

必要的批次欄位

欄位	值
要求	`Array<CreateTasksRequest>`

選用的批次工作欄位

欄位	值
標頭	`DeliveryRequestHeader`

建立一批工作

以下範例說明如何建立自取和運送工作使用 Java gRPC 程式庫，或是如何向 HTTP REST 要求提出 HTTP REST 要求 BatchCreateTask。

gRPC

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

DeliveryServiceBlockingStub deliveryService =
  DeliveryServiceGrpc.newBlockingStub(channel);

// Delivery Task settings
Task deliveryTask = Task.newBuilder()
  .setType(Task.Type.DELIVERY)
  .setState(Task.State.OPEN)
  .setTrackingId("delivery-tracking-id")
  .setPlannedLocation(               // Grand Indonesia East Mall
    LocationInfo.newBuilder().setPoint(
      LatLng.newBuilder().setLatitude(-6.195139).setLongitude(106.820826)))
  .setTaskDuration(
    Duration.newBuilder().setSeconds(2 * 60))
  .build();

// Delivery Task request
CreateTaskRequest createDeliveryTaskRequest =
  CreateTaskRequest.newBuilder()  // No need for the header or parent fields
      .setTaskId("task-8312508")  // Task ID assigned by the Provider
      .setTask(deliveryTask)      // Initial state
      .build();

// Pickup Task settings
Task pickupTask = Task.newBuilder()
  .setType(Task.Type.PICKUP)
  .setState(Task.State.OPEN)
  .setTrackingId("pickup-tracking-id")
  .setPlannedLocation(               // Grand Indonesia East Mall
    LocationInfo.newBuilder().setPoint(
      LatLng.newBuilder().setLatitude(-6.195139).setLongitude(106.820826)))
  .setTaskDuration(
    Duration.newBuilder().setSeconds(2 * 60))
  .build();

// Pickup Task request
CreateTaskRequest createPickupTaskRequest =
  CreateTaskRequest.newBuilder()  // No need for the header or parent fields
      .setTaskId("task-8241890")  // Task ID assigned by the Provider
      .setTask(pickupTask)        // Initial state
      .build();

// Batch Create Tasks settings
String parent = "providers/" + PROJECT_ID;

// Batch Create Tasks request
BatchCreateTasksRequest batchCreateTasksRequest =
  BatchCreateTasksRequest.newBuilder()
      .setParent(parent)
      .addRequests(createDeliveryTaskRequest)
      .addRequests(createPickupTaskRequest)
      .build();

// Error handling
// If Fleet Engine does not have any task(s) with these task ID(s) and the
// credentials of the requestor pass, the service creates the task(s)
// successfully.

try {
  BatchCreateTasksResponse createdTasks = deliveryService.batchCreateTasks(
    batchCreateTasksRequest);
} catch (StatusRuntimeException e) {
  Status s = e.getStatus();
  switch (s.getCode()) {
    case ALREADY_EXISTS:
      break;
    case PERMISSION_DENIED:
      break;
  }
  return;
}

REST

如要在伺服器環境中建立送貨和取貨工作，請向 BatchCreateTasks 發出的 HTTP REST 呼叫：

POST https://fleetengine.googleapis.com/v1/providers/<project_id>/batchCreate

<id> 是工作的專屬 ID。

要求標頭必須包含 Authorization 欄位，當中須有相應的值 不記名 <token>，其中 <token> 是由您的伺服器核發服務帳戶角色中所述的指南，以及 JSON Web 權杖。

要求主體必須包含 BatchCreateTasksRequest 實體。

curl 指令範例：

# Set $JWT, $PROJECT_ID, $DELIVERY_TRACKING_ID, $DELIVERY_TASK_ID,
# $PICKUP_TRACKING_ID, and $PICKUP_TASK_ID in the local environment
curl -X POST "https://fleetengine.googleapis.com/v1/providers/${PROJECT_ID}/tasks:batchCreate" \
 -H "Content-type: application/json" \
 -H "Authorization: Bearer ${JWT}" \
