成功使用这个SO解决方案大约一年了，我获取Google AdWords广告系列每日费用的代码如下：
sum += campaign.campaignStats.cost.microAmount / 1000000m;
campaignStats不幸的是，在 API 的最新版本 v201309 中，此属性不再存在。
我搜索了官方 .NET 包装器的所有示例，还浏览了 API 文档，只是没有找到任何关于如何管理它的线索。
因此我的问题是：
如何通过最新的 Google AdWords API 检索 AdWord 广告系列的每日费用？
更新1：
我在 AdWords API 论坛中找到了 此讨论。他们建议生成一份报告，获取并解析该报告。还有关于它的 AdWords 博客文章。
这是 PHP 版本：
$filePath = tempnam('/tmp','adwordsreport');
$user = new AdWordsUser(NULL, NULL, NULL, $developerToken, $applicationToken, $userAgent, $ClientID, NULL, NULL, $oauth2Info);
$user->SetClientId($ClientID);
// Log SOAP XML request and response.
$user->LogDefaults();
$user->LoadService('ReportDefinitionService', 'v201402');
// Create selector.
$selector = new Selector();
$selector->fields = array('CampaignId', 'AdGroupId', 'Id', 'Criteria',
'CriteriaType', 'Impressions', 'Clicks', 'Cost');
// Filter out deleted criteria.
$selector->predicates[] = new Predicate('Status', 'NOT_IN', array('DELETED'));
// Create report definition.
$reportDefinition = new ReportDefinition();
$reportDefinition->selector = $selector;
$reportDefinition->reportName = 'Criteria performance report #' . uniqid();
$reportDefinition->dateRangeType = 'ALL_TIME';
$reportDefinition->reportType = 'CRITERIA_PERFORMANCE_REPORT';
$reportDefinition->downloadFormat = 'XML';
// Exclude criteria that haven't recieved any impressions over the date range.
$reportDefinition->includeZeroImpressions = FALSE;
// Set additional options.
$options = array('version' => 'v201402', 'returnMoneyInMicros' => TRUE);
// Download report.
ReportUtils::DownloadReport($reportDefinition, $filePath, $user, $options);
printf("Report with name '%s' was downloaded to '%s'.\n",
$reportDefinition->reportName, $filePath);
$doc = new DOMDocument();
$doc->loadXML(file_get_contents($filePath));
$xp = new DOMXPath($doc);
$q = $xp->query("/report/table/row/@cost");
$cost = 0;
foreach($q as $el) {
$v = $el->textContent;
$cost += $v / 1000000;
}
echo $cost;
这是我想出的可行解决方案：
private static decimal coreGetAdwordsSumInRange(DateTime start, DateTime end)
{
var reportDefinition =
new ReportDefinition
{
reportName = string.Format(@"Campaign performance report #{0}", DateTime.Now.Ticks),
dateRangeType = ReportDefinitionDateRangeType.CUSTOM_DATE,
reportType = ReportDefinitionReportType.CAMPAIGN_PERFORMANCE_REPORT,
downloadFormat = DownloadFormat.XML,
includeZeroImpressions = false,
selector = new Selector
{
fields = new[] { @"Cost" },
dateRange = new DateRange {min = start.ToString(@"yyyyMMdd"), max = end.ToString(@"yyyyMMdd")}
}
};
// --
var sum = decimal.Zero;
var tempFilePath = Path.Combine(Path.GetTempPath(), Guid.NewGuid() + @".xml");
try
{
var utils = new ReportUtilities(new AdWordsUser()) { ReportVersion = @"v201309" };
utils.DownloadClientReport(reportDefinition, true, tempFilePath);
var doc = new XmlDocument();
doc.Load(tempFilePath);
var costNodes = doc.SelectNodes(@"/report/table/row/@cost");
if (costNodes != null)
{
foreach (XmlNode costNode in costNodes)
{
var cost = Convert.ToDecimal(costNode.InnerText);
sum += cost/1000000m;
}
}
}
finally
{
File.Delete(tempFilePath);
}
return sum;
}
使用
PHPv201506v201509function getAdwordSumOfCost(AdWordsUser $user, $filePath, $startDate=null, $endDate=null, $campaignId = null) {
$basePath = __DIR__."/../../";//path to google ads api
// Load the service, so that the required classes are available.
$user->LoadService('ReportDefinitionService', 'v201509');
include_once($basePath.'vendor/googleads/googleads-php-lib/src/Google/Api/Ads/AdWords/v201509/CampaignService.php');
$selector = new Selector();
$selector->fields = array('CampaignId', 'AdGroupId', 'Id', 'Criteria',
'CriteriaType', 'Impressions', 'Clicks', 'Cost');
if($campaignId)
$selector->predicates[] = new Predicate('CampaignId', 'IN', array($campaignId));
if($startDate && $endDate) {
$selector->dateRange = new DateRange($startDate, $endDate);
}
// Create report definition.
include_once($basePath.'vendor/googleads/googleads-php-lib/src/Google/Api/Ads/AdWords/Util/v201509/ReportClasses.php');
$reportDefinition = new ReportDefinition();
$reportDefinition->selector = $selector;
$reportDefinition->reportName = 'Criteria performance report #' . uniqid();
$reportDefinition->dateRangeType = 'CUSTOM_DATE';
$reportDefinition->reportType = 'CRITERIA_PERFORMANCE_REPORT';
$reportDefinition->downloadFormat = 'XML';
// Exclude criteria that haven't recieved any impressions over the date range.
$reportDefinition->includeZeroImpressions = false;
// Set additional options.
$options = array('version' => 'v201509');
// Download report.
include_once($basePath.'vendor/googleads/googleads-php-lib/src/Google/Api/Ads/AdWords/Util/v201509/ReportUtils.php');
ReportUtils::DownloadReport($reportDefinition, $filePath, $user, $options);
$doc = new DOMDocument();
$doc->loadXML(file_get_contents($filePath));
$xp = new DOMXPath($doc);
$q = $xp->query("/report/table/row/@cost");
$cost = 0.00;
foreach($q as $el) {
$v = $el->textContent;
$cost += $v / 1000000;
}
return $cost;
}
用途：
$adwordsUser = new AdWordsUser();
//pass Adwords clientID, you can also pas campaign id as well if you want to get calculation only for a single campaign
$adwords = new Adwords('111-111-111');
//Will give you cost for yesterday
$cost = $adwords->getAdwordSumOfCost($adwordsUser, '/path/to/storage/result.xml', date('Ymd', strtotime('-1 day')), date('Ymd', strtotime('-1 day')));
