Permguard Python SDK (Authorization Check) - https://www.permguard.com

Permguard Python SDK

The Permguard Python SDK provides a simple and flexible client to perform authorization checks against a Permguard Policy Decision Point (PDP) service using gRPC. Plase refer to the Permguard Documentation for more information.

Usage Example

Below is a sample Python code demonstrating how to create a Permguard client, build an authorization request using a builder pattern, and process the authorization response:

from permguard.az.azreq.builder_principal import PrincipalBuilder
from permguard.az.azreq.builder_request_atomic import AZAtomicRequestBuilder
from permguard.az_client import AZClient
from permguard.az_config import with_endpoint


az_client = AZClient(with_endpoint("localhost", 9094))

principal = PrincipalBuilder("[e-mail]").build()

entities = [
    {
        "uid": {"type": "MagicFarmacia::Platform::BranchInfo", "id": "subscription"},
        "attrs": {"active": True},
        "parents": [],
    }
]

req = (
    AZAtomicRequestBuilder(
        895741663247,
        "809257ed202e40cab7e958218eecad20",
        "platform-creator",
        "MagicFarmacia::Platform::Subscription",
        "MagicFarmacia::Platform::Action::create",
    )
    .with_request_id("1234")
    .with_principal(principal)
    .with_entities_items("cedar", entities)
    .with_subject_role_actor_type()
    .with_subject_source("keycloack")
    .with_subject_property("isSuperUser", True)
    .with_resource_id("e3a786fd07e24bfa95ba4341d3695ae8")
    .with_resource_property("isEnabled", True)
    .with_action_property("isEnabled", True)
    .with_context_property("time", "2025-01-23T16:17:46+00:00")
    .with_context_property("isSubscriptionActive", True)
    .build()
)

ok, response = az_client.check(req)

if ok:
    print("✅ authorization permitted")
else:
    print("❌ authorization denied")
    if response and response.context:
        if response.context.reason_admin:
            print(f"-> reason admin: {response.context.reason_admin.message}")
        if response.context.reason_user:
            print(f"-> reason user: {response.context.reason_user.message}")
        for eval in response.evaluations:
            if eval.context and eval.context.reason_user:
                print(f"-> reason admin: {eval.context.reason_admin.message}")
                print(f"-> reason user: {eval.context.reason_user.message}")
    if response and response.evaluations:
        for eval in response.evaluations:
            if eval.context:
                if eval.context.reason_admin:
                    print(f"-> evaluation requestid {eval.request_id}: reason admin: {eval.context.reason_admin.message}")
                if eval.context.reason_user:
                    print(f"-> evaluation requestid {eval.request_id}: reason user: {eval.context.reason_user.message}")

Version Compatibility

Our SDK follows a versioning scheme aligned with the PermGuard server versions to ensure seamless integration. The versioning format is as follows:

SDK Versioning Format: x.y.z

• x.y: Indicates the compatible PermGuard server version.
• z: Represents the SDK's patch or minor updates specific to that server version.

Compatibility Examples:

• SDK Version 1.3.0 is compatible with PermGuard Server 1.3.
• SDK Version 1.3.1 includes minor improvements or bug fixes for PermGuard Server 1.3.

Incompatibility Example:

• SDK Version 1.3.0 may not be guaranteed to be compatible with PermGuard Server 1.4 due to potential changes introduced in server version 1.4.

Important: Ensure that the major and minor versions (x.y) of the SDK match those of your PermGuard server to maintain compatibility.
