超时

所有 Google Ads API 服务都有默认设置（包括超时），这些设置由传输使用。给定 Google Ads API 版本的任何服务都有一个专用 JSON 文件，其中定义了服务和方法级别的这些默认设置。例如，您可以在 GitHub 上找到最新 Google Ads API 版本的服务资源配置文件。

默认设置足以满足大多数使用情形，但有时您可能需要替换这些设置。适用于 PHP 的客户端库支持针对服务器流式传输调用和一元调用替换每次调用的超时设置（使用 timeoutMillis 选项以毫秒为单位指定）。

虽然您可以在客户端库中配置较高的超时值（例如 2 小时或更长时间），但底层网络代理或 API 服务器仍可能会提前终止长时间运行的请求，并返回 DEADLINE_EXCEEDED 状态错误。

替换服务器流式传输调用的超时

唯一使用服务器流式传输调用的 Google Ads API 服务方法是 GoogleAdsService.SearchStream。如需替换默认超时时间，请在调用方法时，在可选的调用选项数组中传递 timeoutMillis（以毫秒为单位）：

    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 = $googleAdsServiceClient->searchStream(
                SearchGoogleAdsStreamRequest::build($customerId, $query),
                [
                    // Any server streaming call has a default timeout setting. For this
                    // particular call, the default setting can be found in the following file:
                    // https://github.com/googleads/google-ads-php/blob/master/src/Google/Ads/GoogleAds/V25/Services/resources/google_ads_service_client_config.json.
                    //
                    // When making a server streaming call, an optional argument is provided and can
                    // be used to override the default timeout setting with a given value.
                    'timeoutMillis' => self::CLIENT_TIMEOUT_MILLIS
                ]
            );
            // Iterates over all rows in all messages and collects the campaign IDs.
            foreach ($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;
        }
    }

替换一元调用的超时

大多数 Google Ads API 服务方法都使用一元调用；典型示例包括 GoogleAdsService.Search 和 GoogleAdsService.Mutate。如需替换默认超时时间，请在调用方法时，在可选的调用选项数组中传递 timeoutMillis（以毫秒为单位）：

    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 = $googleAdsServiceClient->search(
                SearchGoogleAdsRequest::build($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/V25/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;
        }
    }
