所有 Google Ads API 服務都有預設設定,包括由傳輸所使用的逾時設定。特定 Google Ads API 版本的任何服務都會提供專屬的 JSON 檔案,其中會在服務和方法層級定義這些預設設定。舉例來說,您可以前往這個頁面,查看與最新版 Google Ads API 相關的檔案。
預設設定適用於大多數用途,但有時您可能需要覆寫這些設定。PHP 用戶端程式庫支援覆寫伺服器串流和一元運算呼叫的逾時設定。
您可以將逾時時間設為 2 小時或更長,但 API 仍可能會針對執行時間極長的要求逾時,並傳回 DEADLINE_EXCEEDED
錯誤。
覆寫伺服器串流呼叫的逾時值
唯一使用這類呼叫的 Google Ads API 服務方法是 GoogleAdsService.SearchStream
。如要覆寫預設逾時時間,您需要在呼叫方法時新增額外參數:
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, $query), [ // Any server streaming call has a default timeout setting. For this // particular call, the default setting can be found in the following file: // https://github.com/googleads/google-ads-php/blob/master/src/Google/Ads/GoogleAds/V18/Services/resources/google_ads_service_client_config.json. // // When making a server streaming call, an optional argument is provided and can // be used to override the default timeout setting with a given value. 'timeoutMillis' => self::CLIENT_TIMEOUT_MILLIS ] ); // Iterates over all rows in all messages and collects the campaign IDs. foreach ($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; } }
覆寫一元呼叫的逾時時間
大多數 Google Ads API 服務方法都會使用一元呼叫,例如 GoogleAdsService.Search
和 GoogleAdsService.Mutate
。如要覆寫預設逾時時間,您需要在呼叫方法時新增額外參數:
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, $query), [ // Any unary call is retryable and has default retry settings. // Complete information about these settings can be found here: // https://googleapis.github.io/gax-php/master/Google/ApiCore/RetrySettings.html. // For this particular call, the default retry settings can be found in the // following file: // https://github.com/googleads/google-ads-php/blob/master/src/Google/Ads/GoogleAds/V18/Services/resources/google_ads_service_client_config.json. // // When making an unary call, an optional argument is provided and can be // used to override the default retry settings with given values. 'retrySettings' => [ // Sets the maximum accumulative timeout of the call, it includes all tries. 'totalTimeoutMillis' => self::CLIENT_TIMEOUT_MILLIS, // Sets the timeout that is used for the first try to one tenth of the // maximum accumulative timeout of the call. // Note: This overrides the default value and can lead to // RequestError.RPC_DEADLINE_TOO_SHORT errors when too small. We recommend // to do it only if necessary. 'initialRpcTimeoutMillis' => self::CLIENT_TIMEOUT_MILLIS / 10, // Sets the maximum timeout that can be used for any given try to one fifth // of the maximum accumulative timeout of the call (two times greater than // the timeout that is used for the first try). 'maxRpcTimeoutMillis' => self::CLIENT_TIMEOUT_MILLIS / 5 ] ] ); // Iterates over all rows in all messages and collects the campaign IDs. foreach ($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; } }
