啟用委刊項

所有使用 Display & Video 360 API 建立的委刊項，一開始都是草稿狀態。處於這個草稿狀態的委刊項不會放送廣告，因此您可以隨意調整設定和指定目標，不會影響目前廣告放送。本頁說明應採取哪些步驟來確認您的委刊項已可放送廣告，以及將狀態更新為有效狀態。

啟用前應採取的行動

由於委刊項是廣告收益和廣告放送的支出方式，您必須確保委刊項在啟用後會正常放送廣告。啟用委刊項前， 請考量以下事項：

• 確認檔期設定正確無誤：檢查委刊項的 flight 欄位，確認委刊項的檔期視窗設定正確無誤。您可以自訂委刊項的檔期視窗，或由上層廣告訂單沿用。
• 確認沒有警告導致委刊項放送功能遭到封鎖：使用 advertisers.lineItems.get 擷取委刊項資源，然後檢查 warningMessages 欄位，確認委刊項沒有任何警告可能導致委刊項放送受限。LineItemWarningMessage 列舉會記錄每個警告的影響。
• 確認所有父項資源也都處於有效狀態：如果有效委刊項的上層廣告客戶、廣告活動或廣告訂單並非有效，就不會開始放送廣告。在廣告客戶、廣告活動和廣告訂單服務中使用 GET 方法擷取這些資源。

啟用委刊項

將委刊項的 entityStatus 欄位更新為 ENTITY_STATUS_ACTIVE，即可啟用委刊項。您可以使用 advertisers.lineItems.patch 方法，更新單一委刊項的這個欄位，也可以針對某個廣告客戶中的多個委刊項更新這個欄位。使用 advertisers.lineItems.bulkUpdate 即可。

警告： 請勿同時提出 patch 或 bulkUpdate 要求與更新相同委刊項或指定目標的其他要求。

以下範例說明如何使用 bulkUpdate 啟用多個委刊項：

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);
    }
}
