基本用法

用戶端程式庫的基本用法如下：

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.

建立 GoogleAdsClient 執行個體

Google Ads API PHP 程式庫中最重要的類別是 GoogleAdsClient 類別。您可以使用這個程式庫建立預先設定的服務用戶端物件，用於發出 API 呼叫。GoogleAdsClient 提供多種執行個體化方式：

• 使用 google_ads_php.ini 檔案。
• 使用環境變數。
• 在 GoogleAdsClientBuilder 上使用設定器。

詳情請參閱設定指南。

如要設定 GoogleAdsClient 物件，請建立 OAuth2TokenBuilder 物件和 GoogleAdsClientBuilder 物件，並設定必要設定：

// 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();

建立服務

GoogleAdsClient 會為每個服務用戶端物件提供 getter 方法。 舉例來說，如要建立 CampaignServiceClient 的例項，請呼叫 GoogleAdsClient->getCampaignServiceClient() 方法，如上一個範例所示。

處理錯誤

並非每次 API 呼叫都會成功。如果 API 呼叫因故失敗，伺服器可能會擲回錯誤。請務必擷取 API 錯誤並妥善處理。

發生 API 錯誤時，系統會擲回 GoogleAdsException 例項。這份報告包含詳細資料，可協助您找出問題原因：

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
    );
}
