如何将 Google 服务 oAuth2 转变为 Google 广告 API oAuth2 访问

Question

所以我正在为 PHP 使用 Google API 客户端并且我有一个有效的 OAuth 流程，

class GoogleClient {
    private static $client_id = "1050479587066-f64vq210hc2m15fdj4r77g8ml7jin30d.apps.googleusercontent.com";
    private static $client_Secret = "CK8orQfPNpD9UgF0bqNJinVI";
    private static $redirect_uri = '/return.php';

    private static $access;

    private static $client = null;

    private static function checkForAccess(){
        if(isset(self::$access)){
            return true;
        }

        if(isset($_SESSION['GoogleAuth'])){
            self::$access = $_SESSION['GoogleAuth'];
            return true;
        }
        return false;
    }

    public static function GetClient(){
        if(is_null(self::$client)){
            $params = [
                "client_id" => self::$client_id,
                "client_secret" => self::$client_Secret,
                "redirect_uri" => self::$redirect_uri,
                "application_name" => "Test AdWords System"
            ];
            if(self::checkForAccess() && self::isLoggedIn()){
                $param["access_token"] =  self::$access['access_token'];
            }
             //Create and Request to access Google API
            $client = new Google_Client($params);
        }
        return $client;
    }

    public static function doLogin(){
        $scopes = [ 'https://www.googleapis.com/auth/adwords', 'https://www.googleapis.com/auth/dfp',  "https://www.googleapis.com/auth/userinfo.email"];
        return self::GetClient()->createAuthUrl($scopes);
    }

    public static function doLoginFinal(){
        if (!$code = $_GET['code']) {
            throw new Exception("Auth Code is missing.");
        }

        $authResponse = self::GetClient()->authenticate($code);
        if (isset($authResponse['error'])) {
            throw new Exception(
                "Unable to get access token.", 
                null, 
                new Exception(
                    "{$authResponse['error']} {$authResponse['error_description']}"
                )
            );
        }

        $_SESSION['GoogleAuth'] = $authResponse;
        self::$access = $authResponse;
    }

    public static function isLoggedIn(){
        if(self::checkForAccess()){
            if(isset(self::$access)){
                $expiresAt = @self::$access['created']+@self::$access['expires_in'];
                return (time() < $expiresAt);
            }
        }
        return false;
    }

    public static function GetExpiry(){
        if(self::checkForAccess()){
            return self::$access['created']+self::$access['expires_in'];
        }
        throw new Exception("The User is not logged into a google account.");
    }
}

现在这个 class 正在工作我可以登录并且我有 google-adwords 的范围问题是由于 googleads-php-lib[ 的文档不完善造成的=24=]

所以从示例到 getCampaigns it uses $oAuth2Credential = (new OAuth2TokenBuilder())->fromFile()->build(); but i don't have a file so i went into the OAuth2TokenBuilder 文件，我无法弄清楚如何将已经生成的访问令牌提供给 googleads 对象。

我仔细检查了 google-php-api-client services repo，没有我可以使用的 adwords 服务。

我一直在研究 googleads-php-lib 的源文件，看看我是否能找到实现它的方法，但到目前为止我只是被卡住了，因为一切似乎都需要特定的参数类型，所以我可以装配一些东西来提供细节，但代码似乎总是依赖于多个 class，所以我不能只构建一个扩展 class 的代码。我通过了。

测试成功后密钥将被销毁！

经过数天对源文件的挖掘和修改，我终于找到了一个可行的实现。

这是添加到我的 GoogleClient Static 的两个新方法 Class

private static $developerToken = "";

private static function GetUserRefreshCredentials(){
    return new UserRefreshCredentials(
            null,
            [
                'client_id' => self::$client_id,
                'client_secret' => self::$client_secret,
                'refresh_token' => self::$access['refresh_token']
            ]
        );
}

public function GetAdwordsSession(){
    $builder = new AdWordsSessionBuilder();
    $builder->defaultOptionals();
    $builder->withDeveloperToken(slef::$developerToken);
    return $builder->withOAuth2Credential(self::GetUserRefreshCredentials())->build();
}
