Google Adwords API服務器到服務器的調用

Question

我已成功請求對我的Adwords客戶中心的API訪問。

現在，我想提供一個免費的小型Webtool，它使用“估算的關鍵字點擊量服務”。 （用戶填寫關鍵字和區域並獲得潛力）

我已經閱讀了很多有關Google API的文章。 但是，老實說，我是OAuth的新手。

是否真的有必要通過OAuth對每個用戶進行身份驗證，或者是否可以進行服務器到服務器的調用（php）？ 是否有任何教程或示例？

謝謝你的提示

要獲取關鍵字，請通過對adwords api示例進行一些修改來估算由我編寫的以下功能帶來的點擊量

請參閱此鏈接獲取Google Adwords示例。

注意：您必須將credantials（ClientId，RefreshToken，ClientSecret，DeveloperToken）設置到以下文件中：\\ lib \\ Google \\ Api \\ Ads \\ AdWords \\ auth.ini

通過包含init.php文件來加載您的api庫。您可以將此文件添加到Google adwords庫中

require_once dirname(dirname(__FILE__)) . '/init.php';
$location = 2840;//Location unitedStates
$language = 1000;//for english language
$max_cpc = 1;
$keywords = array("Keywords1","Keywords2");

$user = new AdWordsUser();
$estimateData = estimateTraffic($user,$keywords,$location,$language,$max_cpc);


function estimateTraffic(AdWordsUser $user,$kws,$country,$lang,$max_cpc) {
        $trafficEstimatorService = $user->GetService('TrafficEstimatorService', ADWORDS_VERSION);
        if(!is_numeric($max_cpc) || empty($max_cpc)){
            $max_cpc = 1;
        }
        $keywords = array();
        foreach($kws as $v){
            $keywords[] = new Keyword($v, 'BROAD');
        }

        // Create a keyword estimate request for each keyword.
        $keywordEstimateRequests = array();
        foreach ($keywords as $keyword) {
            $keywordEstimateRequest = new KeywordEstimateRequest();
            $keywordEstimateRequest->keyword = $keyword;
            $keywordEstimateRequests[] = $keywordEstimateRequest;
        }

        // Create ad group estimate requests.
        $adGroupEstimateRequest = new AdGroupEstimateRequest();
        $adGroupEstimateRequest->keywordEstimateRequests = $keywordEstimateRequests;

        // Set targeting criteria. Only locations and languages are supported.
        $unitedStates = new Location();
