Semua layanan Google Ads API memiliki setelan default, termasuk waktu tunggu yang digunakan oleh transpor. Setiap layanan dari versi Google Ads API tertentu memiliki file JSON khusus dengan setelan default yang ditentukan pada layanan dan metode level organisasi. Misalnya, Anda dapat menemukan file yang terkait dengan Google Ads API terbaru versi di sini.
Setelan default memadai untuk sebagian besar kasus penggunaan, tetapi terkadang ada ketika Anda perlu menggantinya. Library klien untuk PHP mendukung penggantian pengaturan waktu tunggu untuk streaming server dan panggilan unary.
Anda dapat menyetel waktu tunggu ke 2 jam atau lebih, tetapi API mungkin masih kehabisan waktu
permintaan yang berjalan sangat lama dan menampilkan
Error DEADLINE_EXCEEDED.
Mengganti waktu tunggu untuk panggilan streaming server
Satu-satunya metode layanan Google Ads API yang menggunakan jenis panggilan ini adalah
GoogleAdsService.SearchStream
Untuk mengganti waktu tunggu default, Anda perlu menambahkan parameter ekstra saat memanggil
metode:
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;
}
}
Mengganti waktu tunggu untuk panggilan unary
Sebagian besar metode layanan Google Ads API menggunakan panggilan unary; contoh umumnya adalah
GoogleAdsService.Search dan
GoogleAdsService.Mutate.
Untuk mengganti waktu tunggu default, Anda perlu menambahkan parameter ekstra saat memanggil
metode:
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;
}
