我使用Google Adwords API（v201109）来获取关键字及其搜索量。我已经创建了文件

adwords.php，带有以下代码-

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
$path = dirname(__FILE__) . '/../../../';
set_include_path(get_include_path() . PATH_SEPARATOR . $path);
require_once 'Google/Api/Ads/AdWords/Lib/AdWordsUser.php';
$adwords_username = "myusername@gmail.com";
$adwords_password = "mypassword";
$adwords_developerToken = "mydevelopertoken";
$user = new AdWordsUser(null, $adwords_username, $adwords_password, $adwords_developerToken);
$user->SetDefaultServer("https://adwords.google.com/");
//set Adwords Client Id
$user->SetClientCustomerId('111111111');
$str_group = GetAdGroup($user, "v201509");
echo $str_group;
function GetAdGroup(AdWordsUser $user, $adwords_version) {
    // Get the service, which loads the required classes.
    $adgroupService = $user->GetService('AdGroupService', $adwords_version);
    // Create selector.
    $selector = new Selector();
    $selector->fields = array('Id', 'Name', 'CampaignId', 'Status');
    $selector->ordering[] = new OrderBy('CampaignId', 'ASCENDING');
    // Filter out deleted criteria.
    $selector->predicates[] = new Predicate('Status', 'NOT_IN', array('DELETED', 'PAUSED'));
    // Create paging controls.
    $selector->paging = new Paging(0, AdWordsConstants::RECOMMENDED_PAGE_SIZE);
    $ret = array();
    do {
    //echo "<pre>";print_r($selector);die;
        // Make the get request.
        $page = $adgroupService->get($selector);
        // Display results.
        if (isset($page->entries)) {
            foreach ($page->entries as $adgroup) {
                //printf("AdGroup with name '%s' and id '%s' was found for Campaign: '%s' and Status: '%s''n",
                // $adgroup->name, $adgroup->id, $adgroup->campaignId, $adgroup->status);
                $ret[] = array(
                    'name' => $adgroup->name,
                    'id' => $adgroup->id,
                    'campaignId' => $adgroup->campaignId,
                    'active' => (strcmp($adgroup->status,'ENABLED')==0)?1:0
                );
            }
        } else {
            //print "No adgroups were found.'n";
        }
        // Advance the paging index.
        $selector->paging->startIndex += AdWordsConstants::RECOMMENDED_PAGE_SIZE;
    } while ($page->totalNumEntries > $selector->paging->startIndex);
    return $ret;
}
function GetKeywords(AdWordsUser $user, $adGroupId, $days, $adwords_version) {
    // Get the service, which loads the required classes.
    $adGroupCriterionService = $user->GetService('AdGroupCriterionService', $adwords_version);
    // Create selector.
    $selector = new Selector();
    $selector->fields = array('KeywordText', 'KeywordMatchType', 'Id', 'AverageCpc', 'AveragePosition', 'Clicks', 'Conversions', 'Cost', 'Ctr', 'Impressions', 'QualityScore', 'Status');
    $selector->ordering[] = new OrderBy('KeywordText', 'ASCENDING');
    // Create predicates.
    $selector->predicates[] = new Predicate('AdGroupId', 'IN', array($adGroupId));
    $selector->predicates[] = new Predicate('CriteriaType', 'IN', array('KEYWORD'));
    $selector->predicates[] = new Predicate('Status', 'IN', array('ACTIVE'));
    $selector->predicates[] = new Predicate('Impressions', 'GREATER_THAN', array('1'));
    $dateRange = new DateRange();
    $str1 = '-1 days';
    $str2 = '-1 days';
    if ($days > 0) {
    $str1 = '-' . $days . ' days';
    $str2 = '-' . $days . ' days';
    }
    $dateRange->min = date('Ymd', strtotime($str1));
    $dateRange->max = date('Ymd', strtotime($str2));
    $selector->dateRange = $dateRange;
    // Create paging controls.
    $selector->paging = new Paging(0, AdWordsConstants::RECOMMENDED_PAGE_SIZE);
    $ret = array();
    do {
    // Make the get request.
    $page = $adGroupCriterionService->get($selector);
    // Display results.
    if (isset($page->entries)) {
        foreach ($page->entries as $adGroupCriterion) {
        $cr = 0;
        if ($adGroupCriterion->stats->clicks > 0)
            $cr = $adGroupCriterion->stats->conversions / $adGroupCriterion->stats->clicks;
        $ret[] = array(
            'name' => $adGroupCriterion->criterion->text,
            'type' => $adGroupCriterion->criterion->matchType,
            'id' => $adGroupCriterion->criterion->id,
            'clicks' => $adGroupCriterion->stats->clicks,
            'cpc' => $adGroupCriterion->stats->averageCpc->microAmount / 1000000,
            'conversions' => $adGroupCriterion->stats->conversions,
            'cost' => $adGroupCriterion->stats->cost->microAmount / 1000000,
            'ctr' => $adGroupCriterion->stats->ctr,
            'impressions' => $adGroupCriterion->stats->impressions,
            'qualityfactor' => $adGroupCriterion->qualityInfo->qualityScore,
            'cr' => $cr,
            'position' => $adGroupCriterion->stats->averagePosition
        );
        }
    } else {
        //print "No keywords were found.'n";
    }
    // Advance the paging index.
    $selector->paging->startIndex += AdWordsConstants::RECOMMENDED_PAGE_SIZE;
    } while ($page->totalNumEntries > $selector->paging->startIndex);
    return $ret;
}

但是，当我运行adwords.php文件时，我不断收到以下错误。

错误

致命错误：未捕获的SoapFault异常：[soap:Server][QuotaCheckError.INVALID_TOKEN_HEADER@；触发器：'abhijeetk.aloha@gmail.com']在/var/www/html/Google/Api/Ads/Common/Lib/AdsSoapClient.php：216堆栈跟踪：#0/var/www/html/Google/Api/Ads/Common/Lib/AdsSoapClient.php（216）：SoapClient->__soapCall（'get'，Array，NULL，Array，Array）#1/var/www/html/Google/Api/Ads/AdWords/v2201509/AdGroupService.php（7408）：AdsSoapClient->__soapCall（'get'，Array）#2/var/www/html/adwords.php（46）：AdGroupService->get（对象（选择器））

/第216行上的var/www/html/Google/Api/Ads/Common/Lib/AdsSoapClient.php

我是新手，所以我不知道如何使用API来获取数据。请告诉我我做错了什么。或者我如何使用广告词API来获取关键词及其数量和其他数据。我找到的所有医生都让我更加困惑。

提前感谢
