  // Get the service, which loads the required classes.
  $campaignService = $user->GetService('CampaignService', ADWORDS_VERSION);

  // Create selector.
  $selector = new Selector();
  $selector->fields = array('Id', 'Name','Impressions', 'Clicks');
  $selector->ordering[] = new OrderBy('Name', 'ASCENDING');

  // Create paging controls.
  $selector->paging = new Paging(0, AdWordsConstants::RECOMMENDED_PAGE_SIZE);

  do {
    // Make the get request.
    $page = $campaignService->get($selector);

    // Display results.
    if (isset($page->entries)) {
      foreach ($page->entries as $campaign) {
        printf("Campaign with name '%s' and ID '%s' and Impressions %s was found.\n",
            $campaign->name, $campaign->id,$campaign->impressions);
      }
    } else {
      print "No campaigns were found.\n";
    }

    // Advance the paging index.
    $selector->paging->startIndex += AdWordsConstants::RECOMMENDED_PAGE_SIZE;
  } while ($page->totalNumEntries > $selector->paging->startIndex);

但是得到这个错误：

An error has occurred: [SelectorError.INVALID_FIELD_NAME @ serviceSelector; trigger:'Impressions', SelectorError.INVALID
_FIELD_NAME @ serviceSelector; trigger:'Clicks']

谢谢。

对于像印象、点击和转换这样的性能数据，你必须使用ReportingService。(您不能使用CampaignService查询该信息)使用ReportingService时，您必须使用CAMPAIGN_PERFORMANCE_REPORT。

我建议使用AWQL进行查询，因为它与SQL非常相似。因此，如果您熟悉SQL，那么它就很容易理解。
