Authz Python SDK

This is the Authz development kit for Python.

Installation

You can install in your projects by importing the following dependency:

$ pip install authz-sdk

Usage

You have to instanciate a new Authz Client in your code by doing:

client = authz.Client('localhost:8081', '<client_id>', '<client_secret>')

Once the client is instanciate, you have access to all the gRPC methods under stub property.

In order to create a new Principal, you can use

response = client.stub.PrincipalCreate(proto.PrincipalCreateRequest(
    id='user-123',
    attributes=[
        proto.Attribute(key='email', value='johndoe@acme.tld'),
    ],
))

To declare a new resource:

response = client.stub.ResourceCreate(proto.ResourceCreateRequest(
    id='post.456',
    kind='post',
    value='456',
    attributes=[
        proto.Attribute(key='owner_email', value='johndoe@acme.tld'),
    ],
))

You can also declare a new policy this way:

response = client.stub.PolicyCreate(proto.PolicyCreateRequest(
    id='post-owners',
    resources=['post.*'],
    actions=['edit', 'delete'],
    attribute_rules=[
        'principal.email == resource.owner_email',
    ],
))

Then, you can perform a check with:

is_allowed = client.IsAllowed(
    principal='user-123',
    resource_kind='post',
    resource_value='123',
    action='edit',
)

if is_allowed:
    # do something

Please note that you have access to all the gRPC methods declared here in the proto file.
