啟用委刊項

透過 Display &Video 360 建立的所有委刊項Video 360 API 最初是以草稿建立時間。在草稿狀態中，委刊項不會放送廣告，因此您可以調整設定和指定目標，而不做出這些變更會影響任何目前廣告放送。本頁說明您應採取哪些步驟來確認資料行項目已準備好放送廣告，以及如何將狀態更新為有效。

啟用前應採取的行動

由於委刊項是廣告收益的支出方式購買及放送廣告時，必須確保委刊項則在啟用時正常放送廣告。使用前，請考量以下事項啟用委刊項：

確認檔期設定正確無誤：檢查委刊項的 flight 欄位，確認委刊項設定正確委刊項的檔期可以自訂為或是由上層廣告訂單沿用的委刊項
確認沒有導致委刊項無法放送的警告： 使用 advertisers.lineItems.get 擷取委刊項資源然後查看 warningMessages 欄位，確認委刊項沒有任何可能妨礙委刊項放送的警告。 LineItemWarningMessage 列舉會標註警告。
確認所有父項資源也都處於有效狀態：有效委刊項如果上層廣告客戶、廣告活動或插入項目是上層廣告客戶、廣告活動或廣告，則不會開始放送廣告訂單未啟用。請使用指令中的 GET 方法擷取這些資源廣告客戶、廣告活動和廣告訂單服務。

啟用委刊項

透過更新 entityStatus 欄位來啟用委刊項的 ENTITY_STATUS_ACTIVE。您可以為個別委刊項更新這個欄位使用 advertisers.lineItems.patch 方法和多行時建立一行某個廣告客戶內的多個項目 advertisers.lineItems.bulkUpdate。

以下範例說明如何使用 bulkUpdate 啟動多個委刊項：

Java

// Create the line item structure.
LineItem targetLineItem = new LineItem();
targetLineItem.setEntityStatus("ENTITY_STATUS_ACTIVE");

// Create the bulk update request body.
BulkUpdateLineItemsRequest requestBody = new BulkUpdateLineItemsRequest();
requestBody.setLineItemIds(line-item-ids);
requestBody.setTargetLineItem(targetLineItem);
requestBody.setUpdateMask("entityStatus");

// Configure the bulk update request.
LineItems.BulkUpdate request = service.advertisers().lineItems()
    .bulkUpdate(advertiser-id, requestBody);

// Update the line items.
BulkUpdateLineItemsResponse response = request.execute();

// Display the line items that were updated, failed, and skipped.
if (response.getUpdatedLineItemIds() != null) {
  System.out.printf(
      "The following line item IDs were successfully updated: %s.\n",
      Arrays.toString(response.getUpdatedLineItemIds().toArray()));
}
if (response.getFailedLineItemIds() != null) {
  System.out.printf("The following line item IDs failed to update: %s.\n",
      Arrays.toString(response.getFailedLineItemIds().toArray()));
  if (response.getErrors() != null) {
    System.out.printf(
        "The failed updates were caused by the following errors: %s.\n",
        Arrays.toString(response.getErrors().toArray()));
  }
}
if (response.getSkippedLineItemIds() != null) {
  System.out.printf(
      "The following line items IDs were skipped in the update: %s.\n",
      Arrays.toString(response.getSkippedLineItemIds().toArray()));
}

Python

# Create a line item object with only updated entity status.
line_item_obj = {
    'entityStatus': 'ENTITY_STATUS_ACTIVE'
}

# Build the bulk update request.
bulk_update_request = {
    'lineItemIds': line-item-ids,
    'targetLineItem': line_item_obj,
    'updateMask': "entityStatus"
}

# Update the line items.
response = service.advertisers().lineItems().bulkUpdate(
    advertiserId=advertiser-id,
    body=bulk_update_request
).execute()

# Display the line items that were updated, failed, and skipped.
if 'updatedLineItemIds' in response:
  print("The following line item IDs were updated: %s"
        % response['updatedLineItemIds'])
if 'failedLineItemIds' in response:
  print("The following line item IDs failed to update: %s"
        % response['failedLineItemIds'])
  if 'errors' in response:
    print("The failed updates were caused by the following errors:")
    for error in response["errors"]:
      print("Error code: %s, Message: %s" % (error["code"], error["message"]))
if 'skippedLineItemIds' in response:
  print("The following line items IDs were skipped in the update:: %s"
        % response['skippedLineItemIds'])

PHP

// Create request body.
$body = new Google_Service_DisplayVideo_BulkUpdateLineItemsRequest();
$body->setLineItemIds(line-item-ids);

// Create target line item with updated fields.
$lineItem = new Google_Service_DisplayVideo_LineItem();
$lineItem->setEntityStatus('ENTITY_STATUS_ACTIVE');
$body->setTargetLineItem($lineItem);

// Set update mask in request body.
$body->setUpdateMask("entityStatus");

// Call the API, updating the entity status for the identified line item.
$response = $service->advertisers_lineItems->bulkUpdate(
    advertiser-id,
    $body
);

// Display the line items that were updated, failed, and skipped.
if (!empty($response->getUpdatedLineItemIds())) {
    printf('The following line item IDs were updated:\n');
    foreach ($response->getUpdatedLineItemIds() as $id) {
        printf('%s\n', $id);
    }
}
if (!empty($response->getFailedLineItemIds())) {
    print('The following line item IDs failed to update:\n');
    foreach ($response->getFailedLineItemIds() as $id) {
        printf('%s\n', $id);
    }
    if (!empty($response->getErrors())) {
        print('The failed updates were caused by the following errors:\n');
        foreach ($response->getErrors() as $error) {
            printf(
                'Error Code: %s, Message: %s\n',
                $error->getCode(),
                $error->getMessage()
            );
        }
    }
}
if (!empty($response->getSkippedLineItemIds())) {
    print('The following line item IDs were skipped in the update:\n');
    foreach ($response->getSkippedLineItemIds() as $id) {
        printf('%s\n', $id);
    }
}
