Library klien untuk Python tidak menetapkan waktu tunggu default apa pun, default apa pun yang ditentukan di lapisan transpor gRPC. Ini berarti bahwa, secara {i>default<i}, pustaka klien untuk Python sepenuhnya mendelegasikan perilaku waktu tunggu ke server.
Cukup untuk sebagian besar kasus penggunaan; Namun, jika perlu menentukan waktu tunggu sisi klien, library klien untuk Python mendukung waktu tunggu untuk panggilan streaming dan 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
.
Jika ini menjadi masalah, Anda dapat membagi kueri dan mengeksekusi potongan di
paralel; hal ini untuk menghindari situasi di mana permintaan
yang berjalan lama gagal dan
satu-satunya cara untuk memulihkannya adalah
dengan memulai ulang permintaan.
Waktu tunggu panggilan streaming
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:
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)}")
Waktu tunggu 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:
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)}")
