An initial specification and implementation of an authorization service for the Pan-Canadian Genome Library.

OpenAPI spec in authz_openapi.yaml

Running the test implementation

You can run the test implementation of the service via Docker.

Before running the run.sh script, open the file secrets.sh.example and rename it to secrets.sh. Fill in the values for the secrets, based on the PCGL CILogon test configuration. Ask Daisie on Slack if you need directions on obtaining the secrets.

The run.sh script will use the environment variables listed in secrets.sh and launch three docker containers. The API server will be available at http://localhost:1235.

In order to access any of the REST API endpoints, you will need to get an access code from CILogon and exchange it for an access token:

1. In a browser, go to the authorization endpoint: https://cilogon.org/authorize?response_type=code&client_id=cilogon%3A%2Fclient_id%2F234088ba9c4226f6883f38d7f6af69d6&redirect_uri=http%3A%2F%2Flocalhost%3A1235&scope=openid%2Bprofile%2Bemail%2Borg.cilogon.userinfo. You will probably get an error message, but the URL in the browser bar will look something like https://localhost/?code=NB2HI4D.... Save that as an environment variable, export code=NB2HI4D...

2. Exchange that value for an access token:

curl -X "POST" "https://cilogon.org/oauth2/token" \
     -H 'Content-Type: application/x-www-form-urlencoded; charset=utf-8' \
     --data-urlencode "client_id=$PCGL_CLIENT_ID" \
     --data-urlencode "client_secret=$PCGL_CLIENT_SECRET" \
     --data-urlencode "grant_type=authorization_code" \
     --data-urlencode "redirect_uri=http://localhost" \
     --data-urlencode "code=$code"

3. Use the access token in an Authorization header for any of the API calls:

curl "http://localhost:1235/authz/group/admin" \
 -H 'Authorization: Bearer <token>'

Pytest

There is a basic pytest suite that is primarily designed to test the Opa functionality. Tests to exercise the API calls are still being developed.

Cleanup

Running the clean.sh script will tear down all of the Docker containers.
