La biblioteca cliente de Python no especifica ningún tiempo de espera predeterminado ni se especifica ningún valor predeterminado en la capa de transporte de gRPC. Esto significa que, de forma predeterminada, la biblioteca cliente para Python delega por completo el comportamiento del tiempo de espera al servidor.
Esto es adecuado para la mayoría de los casos de uso. Sin embargo, si es necesario especificar un tiempo de espera del cliente, la biblioteca cliente para Python admite la anulación de tiempo de espera para llamadas unarias y de transmisión.
Puedes establecer el tiempo de espera en 2 horas o más, pero es posible que la API agote el tiempo de espera de las solicitudes de larga duración y muestre un error DEADLINE_EXCEEDED.
Si esto se convierte en un problema, puedes dividir la consulta y ejecutar los fragmentos en paralelo. De esta manera, se evita la situación en la que una solicitud de larga duración falla y la única forma de recuperarla es reiniciar la solicitud.
Tiempos de espera de llamadas de transmisión
El único método del servicio de la API de Google Ads que usa este tipo de llamada es GoogleAdsService.SearchStream.
Para anular el tiempo de espera predeterminado, debes agregar un parámetro adicional cuando llamas al método:
def make_server_streaming_call(client, customer_id):
"""Makes a server streaming call using a custom client timeout.
Args:
client: An initialized GoogleAds client.
customer_id: The str Google Ads customer ID.
"""
ga_service = client.get_service("GoogleAdsService")
campaign_ids = []
try:
search_request = client.get_type("SearchGoogleAdsStreamRequest")
search_request.customer_id = customer_id
search_request.query = _QUERY
stream = ga_service.search_stream(
request=search_request,
# When making any request, an optional "timeout" parameter can be
# provided to specify a client-side response deadline in seconds.
# If not set, then no timeout will be enforced by the client and
# the channel will remain open until the response is completed or
# severed, either manually or by the server.
timeout=_CLIENT_TIMEOUT_SECONDS,
)
for batch in stream:
for row in batch.results:
campaign_ids.append(row.campaign.id)
print("The server streaming call completed before the timeout.")
except DeadlineExceeded as ex:
print("The server streaming call did not complete before the timeout.")
sys.exit(1)
except GoogleAdsException as ex:
print(
f"Request with ID '{ex.request_id}' failed with status "
f"'{ex.error.code().name}' and includes the following errors:"
)
for error in ex.failure.errors:
print(f"\tError with message '{error.message}'.")
if error.location:
for field_path_element in error.location.field_path_elements:
print(f"\t\tOn field: {field_path_element.field_name}")
sys.exit(1)
print(f"Total # of campaign IDs retrieved: {len(campaign_ids)}")
Tiempos de espera de llamadas unarias
La mayoría de los métodos de servicio de la API de Google Ads usan llamadas unarias. Algunos ejemplos típicos son GoogleAdsService.Search y GoogleAdsService.Mutate.
Para anular el tiempo de espera predeterminado, debes agregar un parámetro adicional cuando llamas al método:
def make_unary_call(client, customer_id):
"""Makes a unary call using a custom client timeout.
Args:
client: An initialized GoogleAds client.
customer_id: The Google Ads customer ID.
"""
ga_service = client.get_service("GoogleAdsService")
campaign_ids = []
try:
search_request = client.get_type("SearchGoogleAdsRequest")
search_request.customer_id = customer_id
search_request.query = _QUERY
results = ga_service.search(
request=search_request,
# When making any request, an optional "retry" parameter can be
# provided to specify its retry behavior. Complete information about
# these settings can be found here:
# https://googleapis.dev/python/google-api-core/latest/retry.html
retry=Retry(
# Sets the maximum accumulative timeout of the call; it
# includes all tries.
deadline=_CLIENT_TIMEOUT_SECONDS,
# 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 changing the value only if necessary.
initial=_CLIENT_TIMEOUT_SECONDS / 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 needed for the
# first try).
maximum=_CLIENT_TIMEOUT_SECONDS / 5,
),
)
for row in results:
campaign_ids.append(row.campaign.id)
print("The unary call completed before the timeout.")
except DeadlineExceeded as ex:
print("The unary call did not complete before the timeout.")
sys.exit(1)
except GoogleAdsException as ex:
print(
f"Request with ID '{ex.request_id}' failed with status "
f"'{ex.error.code().name}' and includes the following errors:"
)
for error in ex.failure.errors:
print(f"\tError with message '{error.message}'.")
if error.location:
for field_path_element in error.location.field_path_elements:
print(f"\t\tOn field: {field_path_element.field_name}")
sys.exit(1)
print(f"Total # of campaign IDs retrieved: {len(campaign_ids)}")
