Tempo limite

Todos os serviços da API Google Ads têm configurações padrão, incluindo tempos limite usados pelo transporte. Qualquer serviço de uma determinada versão da API Google Ads tem um arquivo JSON dedicado com essas configurações definidas no nível de serviço e de método. Por exemplo, você pode encontrar os arquivos relacionados à versão mais recente da API Google Ads aqui.

As configurações padrão são adequadas para a maioria dos casos de uso, mas talvez você precise modificá-las. A biblioteca de cliente para PHP é compatível com a substituição de configurações de tempo limite para streaming do servidor e chamadas unárias.

É possível definir o tempo limite como 2 horas ou mais, mas a API ainda pode expirar solicitações extremamente longas e retornar um erro DEADLINE_EXCEEDED.

Como substituir tempos limite para uma chamada de streaming do servidor

O único método de serviço da API Google Ads que usa esse tipo de chamada é GoogleAdsService.SearchStream. Para substituir o tempo limite padrão, adicione um parâmetro extra ao chamar o método:

private static function makeServerStreamingCall(
    GoogleAdsClient $googleAdsClient,
    int $customerId
) {
    $googleAdsServiceClient = $googleAdsClient->getGoogleAdsServiceClient();
    // Creates a query that retrieves all campaign IDs.
    $query = 'SELECT campaign.id FROM campaign';

    $output = '';
    try {
        // Issues a search stream request by setting a custom client timeout.
        /** @var GoogleAdsServerStreamDecorator $stream */
        $stream = $googleAdsServiceClient->searchStream(
            $customerId,
            $query,
            [
                // Any server streaming call has a default timeout setting. For this
                // particular call, the default setting can be found in the following file:
                // https://github.com/googleads/google-ads-php/blob/master/src/Google/Ads/GoogleAds/V11/Services/resources/google_ads_service_client_config.json.
                //
                // When making a server streaming call, an optional argument is provided and can
                // be used to override the default timeout setting with a given value.
                'timeoutMillis' => self::CLIENT_TIMEOUT_MILLIS
            ]
        );
        // Iterates over all rows in all messages and collects the campaign IDs.
        foreach ($stream->iterateAllElements() as $googleAdsRow) {
            /** @var GoogleAdsRow $googleAdsRow */
            $output .= ' ' . $googleAdsRow->getCampaign()->getId();
        }
        print 'The server streaming call completed before the timeout.' . PHP_EOL;
    } catch (ApiException $exception) {
        if ($exception->getStatus() === ApiStatus::DEADLINE_EXCEEDED) {
            print 'The server streaming call did not complete before the timeout.' . PHP_EOL;
        } else {
            // Bubbles up if the exception is not about timeout.
            throw $exception;
        }
    } finally {
        print 'All campaign IDs retrieved:' . ($output ?: ' None') . PHP_EOL;
    }
}
      

Como substituir tempos limite para uma chamada unária

A maioria dos métodos de serviço da API Google Ads usa chamadas unárias. Os exemplos comuns são GoogleAdsService.Search e GoogleAdsService.Mutate. Para substituir o tempo limite padrão, adicione um parâmetro extra ao chamar o método:

private static function makeUnaryCall(GoogleAdsClient $googleAdsClient, int $customerId)
{
    $googleAdsServiceClient = $googleAdsClient->getGoogleAdsServiceClient();
    // Creates a query that retrieves all campaign IDs.
    $query = 'SELECT campaign.id FROM campaign';

    $output = '';
    try {
        // Issues a search request by setting a custom client timeout.
        $response = $googleAdsServiceClient->search(
            $customerId,
            $query,
            [
                // Any unary call is retryable and has default retry settings.
                // Complete information about these settings can be found here:
                // https://googleapis.github.io/gax-php/master/Google/ApiCore/RetrySettings.html.
                // For this particular call, the default retry settings can be found in the
                // following file:
                // https://github.com/googleads/google-ads-php/blob/master/src/Google/Ads/GoogleAds/V11/Services/resources/google_ads_service_client_config.json.
                //
                // When making an unary call, an optional argument is provided and can be
                // used to override the default retry settings with given values.
                'retrySettings' => [
                    // Sets the maximum accumulative timeout of the call, it includes all tries.
                    'totalTimeoutMillis' => self::CLIENT_TIMEOUT_MILLIS,
                    // Sets the timeout that is used for the first try to one tenth of the
                    // maximum accumulative timeout of the call.
                    // Note: This overrides the default value and can lead to
                    // RequestError.RPC_DEADLINE_TOO_SHORT errors when too small. We recommend
                    // to do it only if necessary.
                    'initialRpcTimeoutMillis' => self::CLIENT_TIMEOUT_MILLIS / 10,
                    // Sets the maximum timeout that can be used for any given try to one fifth
                    // of the maximum accumulative timeout of the call (two times greater than
                    // the timeout that is used for the first try).
                    'maxRpcTimeoutMillis' => self::CLIENT_TIMEOUT_MILLIS / 5
                ]
            ]
        );
        // Iterates over all rows in all messages and collects the campaign IDs.
        foreach ($response->iterateAllElements() as $googleAdsRow) {
            /** @var GoogleAdsRow $googleAdsRow */
            $output .= ' ' . $googleAdsRow->getCampaign()->getId();
        }
        print 'The unary call completed before the timeout.' . PHP_EOL;
    } catch (ApiException $exception) {
        if ($exception->getStatus() === ApiStatus::DEADLINE_EXCEEDED) {
            print 'The unary call did not complete before the timeout.' . PHP_EOL;
        } else {
            // Bubbles up if the exception is not about timeout.
            throw $exception;
        }
    } finally {
        print 'All campaign IDs retrieved:' . ($output ?: ' None') . PHP_EOL;
    }
