Tutti i servizi dell'API Google Ads hanno impostazioni predefinite, inclusi i timeout utilizzati dal trasporto. Qualsiasi servizio di una determinata versione dell'API Google Ads dispone di un file JSON dedicato con queste impostazioni predefinite definite a livello di servizio e metodo. Ad esempio, puoi trovare i file relativi alla versione più recente dell'API Google Ads qui.
Le impostazioni predefinite sono adeguate per la maggior parte dei casi d'uso, ma in alcuni casi potrebbe essere necessario eseguirne l'override. La libreria client per PHP supporta l'override delle impostazioni di timeout sia per i flussi di dati del server che per le chiamate unary.
Puoi impostare il timeout su 2 ore o più, ma l'API potrebbe comunque scadere
le richieste a lunga esecuzione e restituire un
errore DEADLINE_EXCEEDED.
Override dei timeout per una chiamata streaming del server
L'unico metodo di servizio dell'API Google Ads che utilizza questo tipo di chiamata è GoogleAdsService.SearchStream.
Per eseguire l'override del timeout predefinito, devi aggiungere un parametro aggiuntivo quando chiami il metodo:
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, $query),
[
// Any server streaming call has a default timeout setting. For this
// particular call, the default setting can be found in the following file:
// https://github.com/googleads/google-ads-php/blob/master/src/Google/Ads/GoogleAds/V17/Services/resources/google_ads_service_client_config.json.
//
// When making a server streaming call, an optional argument is provided and can
// be used to override the default timeout setting with a given value.
'timeoutMillis' => self::CLIENT_TIMEOUT_MILLIS
]
);
// Iterates over all rows in all messages and collects the campaign IDs.
foreach ($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;
}
}
Override dei timeout per una chiamata una tantum
La maggior parte dei metodi di servizio dell'API Google Ads utilizza chiamate unarie; esempi tipici sono GoogleAdsService.Search e GoogleAdsService.Mutate.
Per eseguire l'override del timeout predefinito, devi aggiungere un parametro aggiuntivo quando chiami il metodo:
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, $query),
[
// Any unary call is retryable and has default retry settings.
// Complete information about these settings can be found here:
// https://googleapis.github.io/gax-php/master/Google/ApiCore/RetrySettings.html.
// For this particular call, the default retry settings can be found in the
// following file:
// https://github.com/googleads/google-ads-php/blob/master/src/Google/Ads/GoogleAds/V17/Services/resources/google_ads_service_client_config.json.
//
// When making an unary call, an optional argument is provided and can be
// used to override the default retry settings with given values.
'retrySettings' => [
// Sets the maximum accumulative timeout of the call, it includes all tries.
'totalTimeoutMillis' => self::CLIENT_TIMEOUT_MILLIS,
// Sets the timeout that is used for the first try to one tenth of the
// maximum accumulative timeout of the call.
// Note: This overrides the default value and can lead to
// RequestError.RPC_DEADLINE_TOO_SHORT errors when too small. We recommend
// to do it only if necessary.
'initialRpcTimeoutMillis' => self::CLIENT_TIMEOUT_MILLIS / 10,
// Sets the maximum timeout that can be used for any given try to one fifth
// of the maximum accumulative timeout of the call (two times greater than
// the timeout that is used for the first try).
'maxRpcTimeoutMillis' => self::CLIENT_TIMEOUT_MILLIS / 5
]
]
);
// Iterates over all rows in all messages and collects the campaign IDs.
foreach ($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;
}
