gpcore-sdk 0.2.3

Official Python SDK for the G-PORTAL gpcore API

gpcore-py

The official Python SDK for the G-PORTAL gpcore API.

This is the Python counterpart to gpcore-go. It provides a pre-configured OIDC client and auto-generated protobuf/gRPC bindings for interacting with the gpcore API.

Installation

pip install gpcore-sdk

Usage

The following example authenticates using the client credentials flow and fetches the current user:

import grpc
from gpcore_sdk.client import APIClient
from gpcore_sdk.auth_strategies import (
    ClientCredentialsStrategy,
    CachedAuthStrategy,
)

from gpcore_sdk.protos.gpcore.api.auth.v1.rpc_pb2_grpc import AuthServiceStub
from gpcore_sdk.protos.gpcore.api.admin.v1.requests_pb2 import GetUserRequest


def main():
    auth = ClientCredentialsStrategy(
        client_id="YOUR_CLIENT_ID",
        client_secret="YOUR_CLIENT_SECRET",
    )

    client = APIClient(strategy=CachedAuthStrategy(auth, 30))
    stub = AuthServiceStub(client.channel)

    try:
        response = stub.GetUser(GetUserRequest())
        print(f"User: {response}")
    except grpc.RpcError as e:
        print(f"gRPC error: {e.code()} - {e.details()}")


if __name__ == "__main__":
    main()

Authentication Strategies

Strategy	Description
ClientCredentialsStrategy	OAuth2 client credentials flow. Recommended for service-to-service authentication.
UserPasswordStrategy	Resource owner password flow. Requires a dedicated Keycloak OIDC client.
CachedAuthStrategy	Wrapper that caches and auto-refreshes tokens from any underlying strategy.

Development

Regenerating protobuf bindings

If the API definitions have changed, regenerate the Python protobuf/gRPC code:

scripts/update_proto.sh

Local install

pip install -e .

Releasing

1. Update the version in pyproject.toml.
2. Commit, tag with the version number, and push the tag.
3. The GitHub Actions workflow will build and publish to PyPI automatically.
