# Cloud Asset API . projects

## Instance Methods

Returns the operations Resource.

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.

Close httplib2 connections.

Exports assets with time and resource types to a given Cloud Storage location. The output format is newline-delimited JSON. This API implements the google.longrunning.Operation API allowing you to keep track of the export. We recommend intervals of at least 2 seconds with exponential retry to poll the export operation result. For regular-size resource parent, the export operation usually finishes within 5 minutes.

### Method Details

`batchGetAssetsHistory(parent, readTimeWindow_startTime=None, readTimeWindow_endTime=None, contentType=None, assetNames=None, x__xgafv=None)`

    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.

    Args:
      parent: string, Required. The relative name of the root asset. It can only be an organization number (such as "organizations/123"), a project ID (such as "projects/my-project-id")", or a project number (such as "projects/12345"). (required)
      readTimeWindow_startTime: string, Start time of the time window (exclusive).
      readTimeWindow_endTime: string, End time of the time window (inclusive). If not specified, the current timestamp is used instead.
      contentType: string, Optional. The content type.
        Allowed values
          CONTENT_TYPE_UNSPECIFIED - Unspecified content type.
          RESOURCE - Resource metadata.
          IAM_POLICY - The actual IAM policy set on a resource.
      assetNames: string, A list of the full names of the assets. For example: `//compute.googleapis.com/projects/my_project_123/zones/zone1/instances/instance1`. See [Resource Names](https://cloud.google.com/apis/design/resource_names#full_resource_name) for more info. The request becomes a no-op if the asset name list is empty, and the max size of the asset name list is 100 in one request. (repeated)
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # Batch get assets history response.
        "assets": [ # A list of assets with valid time windows.
          { # An asset in Google Cloud and its temporal metadata, including the time window when it was observed and its status during that window.
            "asset": { # An asset in Google Cloud. An asset can be any resource in the Google Cloud [resource hierarchy](https://cloud.google.com/resource-manager/docs/cloud-platform-resource-hierarchy), a resource outside the Google Cloud resource hierarchy (such as Google Kubernetes Engine clusters and objects), or a policy (e.g. Cloud IAM policy). See [Supported asset types](https://cloud.google.com/asset-inventory/docs/supported-asset-types) for more information. # An asset in Google Cloud.

              "orgPolicy": [ # A representation of an [organization policy](https://cloud.google.com/resource-manager/docs/organization-policy/overview#organization_policy). There can be more than one organization policy with different constraints set on a given resource.
                { # Defines a Cloud Organization `Policy` which is used to specify `Constraints` for configurations of Cloud Platform resources.
                  "constraint": "A String", # The name of the `Constraint` the `Policy` is configuring, for example, `constraints/serviceuser.services`. A [list of available constraints](/resource-manager/docs/organization-policy/org-policy-constraints) is available. Immutable after creation.
                  "restoreDefault": { # Ignores policies set above this resource and restores the `constraint_default` enforcement behavior of the specific `Constraint` at this resource. Suppose that `constraint_default` is set to `ALLOW` for the `Constraint` `constraints/serviceuser.services`. Suppose that organization foo.com sets a `Policy` at their Organization resource node that restricts the allowed service activations to deny all service activations. They could then set a `Policy` with the `policy_type` `restore_default` on several experimental projects, restoring the `constraint_default` enforcement of the `Constraint` for only those projects, allowing those projects to have all services activated. # Restores the default behavior of the constraint; independent of `Constraint` type.
                  },
                  "listPolicy": { # Used in `policy_type` to specify how `list_policy` behaves at this resource. `ListPolicy` can define specific values and subtrees of Cloud Resource Manager resource hierarchy (`Organizations`, `Folders`, `Projects`) that are allowed or denied by setting the `allowed_values` and `denied_values` fields. This is achieved by using the `under:` and optional `is:` prefixes. The `under:` prefix is used to denote resource subtree values. The `is:` prefix is used to denote specific values, and is required only if the value contains a ":". Values prefixed with "is:" are treated the same as values with no prefix. Ancestry subtrees must be in one of the following formats: - "projects/", e.g. "projects/tokyo-rain-123" - "folders/", e.g. "folders/1234" - "organizations/", e.g. "organizations/1234" The `supports_under` field of the associated `Constraint` defines whether ancestry prefixes can be used. You can set `allowed_values` and `denied_values` in the same `Policy` if `all_values` is `ALL_VALUES_UNSPECIFIED`. `ALLOW` or `DENY` are used to allow or deny all values. If `all_values` is set to either `ALLOW` or `DENY`, `allowed_values` and `denied_values` must be unset. # List of values either allowed or disallowed.
                    "allValues": "A String", # The policy all_values state.
                    "allowedValues": [ # List of values allowed at this resource. Can only be set if `all_values` is set to `ALL_VALUES_UNSPECIFIED`.
                      "A String",
                    ],
                    "suggestedValue": "A String", # Optional. The Google Cloud Console will try to default to a configuration that matches the value specified in this `Policy`. If `suggested_value` is not set, it will inherit the value specified higher in the hierarchy, unless `inherit_from_parent` is `false`.
                    "deniedValues": [ # List of values denied at this resource. Can only be set if `all_values` is set to `ALL_VALUES_UNSPECIFIED`.
                      "A String",
                    ],
                    "inheritFromParent": True or False, # Determines the inheritance behavior for this `Policy`. By default, a `ListPolicy` set at a resource supersedes any `Policy` set anywhere up the resource hierarchy. However, if `inherit_from_parent` is set to `true`, then the values from the effective `Policy` of the parent resource are inherited, meaning the values set in this `Policy` are added to the values inherited up the hierarchy. Setting `Policy` hierarchies that inherit both allowed values and denied values isn't recommended in most circumstances to keep the configuration simple and understandable. However, it is possible to set a `Policy` with `allowed_values` set that inherits a `Policy` with `denied_values` set. In this case, the values that are allowed must be in `allowed_values` and not present in `denied_values`. For example, suppose you have a `Constraint` `constraints/serviceuser.services`, which has a `constraint_type` of `list_constraint`, and with `constraint_default` set to `ALLOW`. Suppose that at the Organization level, a `Policy` is applied that restricts the allowed API activations to {`E1`, `E2`}. Then, if a `Policy` is applied to a project below the Organization that has `inherit_from_parent` set to `false` and field all_values set to DENY, then an attempt to activate any API will be denied. The following examples demonstrate different possible layerings for `projects/bar` parented by `organizations/foo`: Example 1 (no inherited values): `organizations/foo` has a `Policy` with values: {allowed_values: "E1" allowed_values:"E2"} `projects/bar` has `inherit_from_parent` `false` and values: {allowed_values: "E3" allowed_values: "E4"} The accepted values at `organizations/foo` are `E1`, `E2`. The accepted values at `projects/bar` are `E3`, and `E4`. Example 2 (inherited values): `organizations/foo` has a `Policy` with values: {allowed_values: "E1" allowed_values:"E2"} `projects/bar` has a `Policy` with values: {value: "E3" value: "E4" inherit_from_parent: true} The accepted values at `organizations/foo` are `E1`, `E2`. The accepted values at `projects/bar` are `E1`, `E2`, `E3`, and `E4`. Example 3 (inheriting both allowed and denied values): `organizations/foo` has a `Policy` with values: {allowed_values: "E1" allowed_values: "E2"} `projects/bar` has a `Policy` with: {denied_values: "E1"} The accepted values at `organizations/foo` are `E1`, `E2`. The value accepted at `projects/bar` is `E2`. Example 4 (RestoreDefault): `organizations/foo` has a `Policy` with values: {allowed_values: "E1" allowed_values:"E2"} `projects/bar` has a `Policy` with values: {RestoreDefault: {}} The accepted values at `organizations/foo` are `E1`, `E2`. The accepted values at `projects/bar` are either all or none depending on the value of `constraint_default` (if `ALLOW`, all; if `DENY`, none). Example 5 (no policy inherits parent policy): `organizations/foo` has no `Policy` set. `projects/bar` has no `Policy` set. The accepted values at both levels are either all or none depending on the value of `constraint_default` (if `ALLOW`, all; if `DENY`, none). Example 6 (ListConstraint allowing all): `organizations/foo` has a `Policy` with values: {allowed_values: "E1" allowed_values: "E2"} `projects/bar` has a `Policy` with: {all: ALLOW} The accepted values at `organizations/foo` are `E1`, E2`. Any value is accepted at `projects/bar`. Example 7 (ListConstraint allowing none): `organizations/foo` has a `Policy` with values: {allowed_values: "E1" allowed_values: "E2"} `projects/bar` has a `Policy` with: {all: DENY} The accepted values at `organizations/foo` are `E1`, E2`. No value is accepted at `projects/bar`. Example 10 (allowed and denied subtrees of Resource Manager hierarchy): Given the following resource hierarchy O1->{F1, F2}; F1->{P1}; F2->{P2, P3}, `organizations/foo` has a `Policy` with values: {allowed_values: "under:organizations/O1"} `projects/bar` has a `Policy` with: {allowed_values: "under:projects/P3"} {denied_values: "under:folders/F2"} The accepted values at `organizations/foo` are `organizations/O1`, `folders/F1`, `folders/F2`, `projects/P1`, `projects/P2`, `projects/P3`. The accepted values at `projects/bar` are `organizations/O1`, `folders/F1`, `projects/P1`.

                  "booleanPolicy": { # Used in `policy_type` to specify how `boolean_policy` will behave at this resource. # For boolean `Constraints`, whether to enforce the `Constraint` or not.
                    "enforced": True or False, # If `true`, then the `Policy` is enforced. If `false`, then any configuration is acceptable. Suppose you have a `Constraint` `constraints/compute.disableSerialPortAccess` with `constraint_default` set to `ALLOW`. A `Policy` for that `Constraint` exhibits the following behavior: - If the `Policy` at this resource has enforced set to `false`, serial port connection attempts will be allowed. - If the `Policy` at this resource has enforced set to `true`, serial port connection attempts will be refused. - If the `Policy` at this resource is `RestoreDefault`, serial port connection attempts will be allowed. - If no `Policy` is set at this resource or anywhere higher in the resource hierarchy, serial port connection attempts will be allowed. - If no `Policy` is set at this resource, but one exists higher in the resource hierarchy, the behavior is as if the`Policy` were set at this resource. The following examples demonstrate the different possible layerings: Example 1 (nearest `Constraint` wins): `organizations/foo` has a `Policy` with: {enforced: false} `projects/bar` has no `Policy` set. The constraint at `projects/bar` and `organizations/foo` will not be enforced. Example 2 (enforcement gets replaced): `organizations/foo` has a `Policy` with: {enforced: false} `projects/bar` has a `Policy` with: {enforced: true} The constraint at `organizations/foo` is not enforced. The constraint at `projects/bar` is enforced. Example 3 (RestoreDefault): `organizations/foo` has a `Policy` with: {enforced: true} `projects/bar` has a `Policy` with: {RestoreDefault: {}} The constraint at `organizations/foo` is enforced. The constraint at `projects/bar` is not enforced, because `constraint_default` for the `Constraint` is `ALLOW`.

A `binding` binds one or more `members` to a single `role`. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": [ "user:eve@example.com" ], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01T00:00:00.000Z')", } } ], "etag": "BwWWja0YfJA=", "version": 3 } **YAML example:** bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time < timestamp('2020-10-01T00:00:00.000Z') - etag: BwWWja0YfJA= - version: 3 For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/). # A representation of the Cloud IAM policy set on a Google Cloud resource. There can be a maximum of one Cloud IAM policy set on any given resource. In addition, Cloud IAM policies inherit their granted access scope from any policies set on parent resources in the resource hierarchy. Therefore, the effectively policy is the union of both the policy set on this resource and each policy set on all of the resource's ancestry resource levels in the hierarchy. See [this topic](https://cloud.google.com/iam/docs/policies#inheritance) for more information.
                "version": 42, # Specifies the format of the policy. Valid values are `0`, `1`, and `3`. Requests that specify an invalid value are rejected. Any operation that affects conditional role bindings must specify version `3`. This requirement applies to the following operations: * Getting a policy that includes a conditional role binding * Adding a conditional role binding to a policy * Changing a conditional role binding in a policy * Removing any role binding, with or without a condition, from a policy that includes conditions **Important:** If you use IAM Conditions, you must include the `etag` field whenever you call `setIamPolicy`. If you omit this field, then IAM allows you to overwrite a version `3` policy with a version `1` policy, and all of the conditions in the version `3` policy are lost. If a policy does not include any conditions, operations on that policy may specify any valid version or leave the field unset.

`exportAssets(parent, body=None, x__xgafv=None)`

    Exports assets with time and resource types to a given Cloud Storage location. The output format is newline-delimited JSON. This API implements the google.longrunning.Operation API allowing you to keep track of the export. We recommend intervals of at least 2 seconds with exponential retry to poll the export operation result. For regular-size resource parent, the export operation usually finishes within 5 minutes.

    Args:
      parent: string, Required. The relative name of the root asset. This can only be an organization number (such as "organizations/123"), a project ID (such as "projects/my-project-id"), a project number (such as "projects/12345"), or a folder number (such as "folders/123"). (required)
      body: object, The request body.
        The object takes the form of:
