kbase-auth-client 0.1.0

Client for the KBase Authentication Service

Auth2 client for Python

This repo contains a minimal client for the KBase Auth2 server, covering only the most common operations - e.g. validating tokens and user names and getting user roles.

Most other uses are easily done with any http/REST client like requests or httpx.

Installation

TODO INSTALL setup a KBase pypi org and publish there

Usage

Both sync and async versions of the client are provided - KBaseAuthClient and AsyncKBaseAuthClient, respectively. Here we demonstrate usage of the async client - to use the sync client, just switch the client name when creating the client and remove the async and await keywords. The examples assume there is a valid KBase token in the token variable.

Note that all methods have internal caches and further caching is not necessary.

Replace the CI environment url with the url of the environment you wish to query.

Get the version of the auth service

from kbase.auth import AsyncKBaseAuthClient

async with await AsyncKBaseAuthClient.create("https://ci.kbase.us/services/auth") as cli:
    print(await cli.service_version())
0.7.2

Get a token

This is the cheapest method to get a KBase username from a token.

from kbase.auth import AsyncKBaseAuthClient

async with await AsyncKBaseAuthClient.create("https://ci.kbase.us/services/auth") as cli:
    print(await cli.get_token(token))
Token(id='67797406-c6a3-4ee0-870d-976739dacd61', user='gaprice', created=1755561300704, expires=1763337300704, cachefor=300000)

Get a user

from kbase.auth import AsyncKBaseAuthClient

async with await AsyncKBaseAuthClient.create("https://ci.kbase.us/services/auth") as cli:
    print(await cli.get_user(token))
User(user='gaprice', customroles=['KBASE_STAFF', 'goofypants'])

Validate usernames

from kbase.auth import AsyncKBaseAuthClient

async with await AsyncKBaseAuthClient.create("https://ci.kbase.us/services/auth") as cli:
    print(await cli.validate_usernames(token, "gaprice", "superfake"))
{'gaprice': True, 'superfake': False}

Without a context manager

The clients can be used without a context manager, in which case the user is responsible for ensuring they're closed:

from kbase.auth import AsyncKBaseAuthClient

cli = await AsyncKBaseAuthClient.create("https://ci.kbase.us/services/auth")

await cli.close()

Development

Creating the synchronous client

The synchronous client is generated from the asynchronous client code - do not make any changes in the _sync directory as they will be overwritten.

To update the synchronous code after modifying the asynchronous code run

uv sync --dev  # only required on first run or when the uv.lock file changes
uv run scripts/process_unasync.py

Adding and releasing code

• Adding code
  • All code additions and updates must be made as pull requests directed at the develop branch.
    • All tests must pass and all new code must be covered by tests.
    • All new code must be documented appropriately
      • Pydocs
      • General documentation if appropriate
      • Release notes
• Releases
  • The main branch is the stable branch. Releases are made from the develop branch to the main branch.
  • Update the version in auth.py and pyproject.toml.
  • Tag the version in git and github.
  • Create a github release.

Testing

uv sync --dev  # only required on first run or when the uv.lock file changes
PYTHONPATH=src uv run pytest test
