Oauth2 Client

Python library responsible for managing users authentication using OAUTH 2.0 Client Backend Application strategy (from non web software to web Oauth2 providers)

Repository:

• https://git.xfel.eu/gitlab/ITDM/oauth2_xfel_client

Dependencies:

• oauthlib (https://pypi.python.org/pypi/oauthlib)
• requests (https://github.com/psf/requests)
• requests-oauthlib (https://github.com/requests/requests-oauthlib)
• pytz (https://pypi.org/project/pytz/)

Installation

Python project """"""""""""""

• Install requirements, if never done before

1.1. For OS X distributions::

1.1.1. Homebrew

    brew install python3

1.1.2 Port

    sudo port install python36

    sudo port select --set python3 python36

    sudo port install py36-pip
    sudo port select --set pip pip36

1.2. For Linux distributions::

sudo apt-get update
sudo apt-get install python3.9

2. Make oauth2_xfel_client library available in your python environment

2.1. Install it via pip::

# Install dependencies from local wheels files
pip install . --no-index --find-links ./external_dependencies/

# Install dependencies from the pypi
pip install .

Installing it will place two folders under the current Python installation site-packages folder:

• oauth2_xfel_client with the sources;
• oauth2_xfel_client-6.1.1.dist-info/ with Wheels configuration files.

To identify your Python site-packages folder run::

python -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())"

Usage

To use this project you need to import it::

from oauth2_xfel_client import Oauth2ClientBackend

• Connection to the Oauth2Client (MyMdC example)::

  from oauth2_xfel_client import Oauth2ClientBackend as Oauth2Client

  Necessary configuration variables to establish a connection

  Go to https://in.xfel.eu/metadata/oauth/applications to make generate

  or re-use a Client/Secret tokens from the metadata catalogue.

  user_id = 'PUT_HERE_YOUR_CLIENT_KEY' user_secret = 'PUT_HERE_YOUR_SECRET_KEY'

  Go to https://in.xfel.eu/metadata/users/edit and copy "Contact email"

  user_email = '[e-mail]'

  URLs for the metadata catalogue

  token_url = 'https://in.xfel.eu/metadata/oauth/token' refresh_url = 'https://in.xfel.eu/metadata/oauth/token' auth_url = 'https://in.xfel.eu/metadata/oauth/authorize' scope = '' base_api_url = 'https://in.xfel.eu/metadata/api/'

  Generate the connection

  oauth_client_valid = Oauth2Client(client_id=user_id, client_secret=user_secret, scope=scope, token_url=token_url, refresh_url=refresh_url, auth_url=auth_url, session_token=None, max_retries=3, timeout=12, ssl_verify=True)

• Interaction with the oauth2Client:

2.1 Example data_group_types::

current_token = oauth_client_valid.get_session_token()

Development & Testing

When developing, and before commit changes, please validate that:

• All tests continue passing successfully (to validate that run pytest)::

  Go to the source code directory

  cd oauth2_xfel_client

  Upgrade package and all its required packages

  pip install . -U --upgrade-strategy eager

  Install test dependencies

  pip install '.[test]' -U --upgrade-strategy eager

  Run all tests using pytest

  pytest

  When running all tests against the standard http application

  OAUTHLIB_INSECURE_TRANSPORT=1 pytest

  Run all tests and get information about coverage for all files inside oauth2_xfel_client package

  pytest --cov oauth2_xfel_client --cov-report term-missing

• Code keeps respecting pycodestyle code conventions (to validate that run pycodestyle)::

  pycodestyle .

• To generate all the wheels files for the dependencies, execute::

  Generate Wheels to itself and dependencies

  pip wheel --wheel-dir=./external_dependencies . pip wheel --wheel-dir=./external_dependencies --find-links=./external_dependencies .

• Check that you have the desired dependency versions in external_dependencies folder, since no versions are now set in setup.py.

Registering library on https://pypi.org

To register this python library, the following steps are necessary::

# Install twine
python -m pip install --upgrade twine

# Generates source distribution (.tar.gz) and wheel (.whl) files in the dist/ folder
python setup.py sdist
python setup.py bdist_wheel

# Upload new version .egg and .whl files
twine upload dist/*

# In case a test is necessary, it is possible to test it against test.pypi.org
twine upload --repository-url https://test.pypi.org/legacy/ dist/* --verbose
