Asset service definition.

Properties

transport

Returns the transport used by the client instance.

Returns

Type	Description
`AssetServiceTransport`	The transport used by the client instance.

Methods

AssetServiceAsyncClient

AssetServiceAsyncClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.asset_v1.services.asset_service.transports.base.AssetServiceTransport] = 'grpc_asyncio', client_options: <module 'google.api_core.client_options' from '/workspace/python-asset/.nox/docfx/lib/python3.9/site-packages/google/api_core/client_options.py'> = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Instantiates the asset service client.

Parameters

Name	Description
`credentials`	`Optional[google.auth.credentials.Credentials]` The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
`transport`	`Union[str, .AssetServiceTransport]` The transport to use. If set to None, a transport is chosen automatically.
`client_options`	`ClientOptions` Custom options for the client. It won't take effect if a `transport` instance is provided. (1) The `api_endpoint` property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto switch to the default mTLS endpoint if client certificate is present, this is the default value). However, the `api_endpoint` property takes precedence if provided. (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the `client_cert_source` property can be used to provide client certificate for mutual TLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used.

Exceptions

Type	Description
`google.auth.exceptions.MutualTlsChannelError`	If mutual TLS transport creation failed for any reason.

analyze_iam_policy

analyze_iam_policy(request: Optional[google.cloud.asset_v1.types.asset_service.AnalyzeIamPolicyRequest] = None, *, retry: google.api_core.retry.Retry = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())

Analyzes IAM policies to answer which identities have what accesses on which resources.

Parameters

Name	Description

`retry`	`google.api_core.retry.Retry` Designation of what errors, if any, should be retried.
`timeout`	`float` The timeout for this request.
`metadata`	`Sequence[Tuple[str, str]]` Strings which should be sent along with the request as metadata.

Returns

Type	Description
`google.cloud.asset_v1.types.AnalyzeIamPolicyResponse`	A response message for AssetService.AnalyzeIamPolicy.

analyze_iam_policy_longrunning

analyze_iam_policy_longrunning(request: Optional[google.cloud.asset_v1.types.asset_service.AnalyzeIamPolicyLongrunningRequest] = None, *, retry: google.api_core.retry.Retry = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())

Analyzes IAM policies asynchronously to answer which identities have what accesses on which resources, and writes the analysis results to a Google Cloud Storage or a BigQuery destination. For Cloud Storage destination, the output format is the JSON format that represents a xref_AnalyzeIamPolicyResponse. This method implements the google.longrunning.Operation][google.longrunning.Operation], which allows you to track the operation status. We recommend intervals of at least 2 seconds with exponential backoff retry to poll the operation result. The metadata contains the request to help callers to map responses to requests.

Parameters

`metadata`	`Sequence[Tuple[str, str]]` Strings which should be sent along with the request as metadata.

Returns

Type	Description
`google.api_core.operation_async.AsyncOperation`	An object representing a long-running operation. The result type for the operation will be AnalyzeIamPolicyLongrunningResponse A response message for AssetService.AnalyzeIamPolicyLongrunning.

Batch gets the update history of assets that overlap a time window. For IAM_POLICY content, this API outputs history when the asset and its attached IAM POLICY both exist. This can create gaps in the output history. Otherwise, this API outputs history with asset in both non-delete or deleted status. If a specified asset does not exist, this API returns an INVALID_ARGUMENT error.
