Usage

from aserto.client import AuthorizerOptions, Identity
from aserto.client.api.authorizer import AuthorizerClient


client = AuthorizerClient(
    identity=Identity(type="NONE"),
    options=AuthorizerOptions(
        api_key=ASERTO_API_KEY,
        tenant_id=ASERTO_TENANT_ID,
        service_type="gRPC",
    ),
)

result = await client.decision_tree(
    decisions=["visible", "enabled", "allowed"],
    policy_instance_name=ASERTO_POLICY_INSTANCE_NAME,
    policy_instance_label=ASERTO_POLICY_INSTANCE_LABEL,
    policy_path_root=ASERTO_POLICY_PATH_ROOT,
    policy_path_separator="DOT",
)

assert result == {
    "GET.your.policy.path": {
        "visible": True,
        "enabled": True,
        "allowed": False,
    },
}

Directory

The Directory APIs can be used to get or set object instances and relation instances. They can also be used to check whether a user has a permission or relation on an object instance.

Directory Client

You can initialize a directory client as follows:

from aserto.client.directory import Directory

ds = Directory.connect(api_key="my_api_key", tenant_id="1234", address="localhost:9292")

• address: hostname:port of directory service (required)
• api_key: API key for directory service (required if using hosted directory)
• tenant_id: Aserto tenant ID (required if using hosted directory)
• cert: Path to the grpc service certificate when connecting to local topaz instance.

'get_object' function

Get a directory object instance with the type and the key.

user = ds.get_object(type="user", key="[e-mail]")

'get_objects' function

Get object instances with an object type type and page size.

from aserto.client.directory import PaginationRequest

users = ds.get_objects(object_type="user", page=PaginationRequest(size=10))

'set_object' function

Create an object instance with the specified fields. For example:

from google.protobuf.json_format import ParseDict
from google.protobuf.struct_pb2 import Struct

properties = ParseDict({"displayName": "test object"}, Struct())

user = ds.set_object(object={
    "type": "user",
    "key": "test-object",
    "properties": properties,
})

'delete_object' function

Delete an object instance using its type and key:

ds.delete_object(type="user", key="test-object")
