基本用法

客户端库的基本用法如下：

use Google\Ads\GoogleAds\Lib\V22\GoogleAdsClient;
use Google\Ads\GoogleAds\Lib\V22\GoogleAdsClientBuilder;
use Google\Ads\GoogleAds\Lib\V22\GoogleAdsException;
use Google\Ads\GoogleAds\Lib\OAuth2TokenBuilder;
use Google\ApiCore\ApiException;

// Generate a refreshable OAuth 2.0 credential for authentication.
$oAuth2Credential = (new OAuth2TokenBuilder())
    ->fromFile()
    ->build();

// Construct a Google Ads client configured from a properties file and the
$googleAdsClient = (new GoogleAdsClientBuilder())
    ->fromFile()
    ->withOAuth2Credential($oAuth2Credential)
    ->withLoginCustomerId(1234567890) // Replace 1234567890 with your login customer ID.
    ->build();

// Create the CampaignServiceClient.
$campaignServiceClient = $googleAdsClient->getCampaignServiceClient();

// Make calls to CampaignServiceClient.

创建 GoogleAdsClient 实例

Google Ads API PHP 库中最重要的类是 GoogleAdsClient 类。借助它，您可以创建预配置的服务客户端对象，用于进行 API 调用。GoogleAdsClient 提供了多种实例化方式：

  • 使用 google_ads_php.ini 文件。
  • 使用环境变量。
  • 在 GoogleAdsClientBuilder 上使用 setter。

如需了解详情，请参阅配置指南。

如需配置 GoogleAdsClient 对象，请创建 OAuth2TokenBuilder 对象和 GoogleAdsClientBuilder 对象，并设置必要的设置：

// Generate a refreshable OAuth 2.0 credential for authentication.
$oAuth2Credential = (new OAuth2TokenBuilder())
    ->fromFile()
    ->build();

// Construct a Google Ads client configured from a properties file
$googleAdsClient = (new GoogleAdsClientBuilder())
    ->fromFile()
    ->withOAuth2Credential($oAuth2Credential)
    ->withLoginCustomerId(1234567890) // Replace 1234567890 with your login customer ID.
    ->build();

创建服务

GoogleAdsClient 为每个服务客户端对象提供了一个 getter 方法。例如，如需创建 CampaignServiceClient 的实例，请调用 GoogleAdsClient->getCampaignServiceClient() 方法，如上一个示例所示。

错误处理

并非每次 API 调用都会成功。如果您的 API 调用因某种原因而失败，服务器可能会抛出错误。捕获 API 错误并妥善处理非常重要。

发生 API 错误时，系统会抛出 GoogleAdsException 实例。其中包含详细信息，可帮助您找出问题所在：

use Google\Ads\GoogleAds\Lib\V22\GoogleAdsException;
use Google\ApiCore\ApiException;

try {
    // Make your API call here.
} catch (GoogleAdsException $googleAdsException) {
    printf(
        "Request with ID '%s' has failed.%sGoogle Ads failure details:%s",
        $googleAdsException->getRequestId(),
        PHP_EOL,
        PHP_EOL
    );
    foreach ($googleAdsException->getGoogleAdsFailure()->getErrors() as $error) {
        printf(
            "\t%s: %s%s",
            $error->getErrorCode()->getErrorCode(),
            $error->getMessage(),
            PHP_EOL
        );
    }
} catch (ApiException $apiException) {
    printf(
        "ApiException was thrown with message '%s'.%s",
        $apiException->getMessage(),
        PHP_EOL
    );
}
