Python#

Installation#

Prerequisites#

Library#

  • Install from Pip - pip install oxdpython

  • Source from Github - Download the zip of the oxd Python library and run the setup script:

cd oxdpython-version
python setup.py install

Configuration#

oxd-python uses a configuration file to specify information needed to configure your OpenID Connect client. If OpenID dynamic client registration is used, the config file needs to be writable by the app, because oxd will save the client id and client secret to this file.

oxd-python can communicate with the oxd server via sockets or HTTPS. There is no difference in code--just toggle the https_extension configuration property. Sockets are used when the oxd server is running locally.

Below are minimal configuration examples for sockets and HTTPS transport. The sample.cfg file contains a full list of configuration parameters and sample values.

Note

The client hostname should be a valid hostname (FQDN), not a localhost or an IP Address.

Configuration for oxd-server via sockets:

[oxd]
host = localhost
port = 8099

[client]
authorization_redirect_uri=https://your.site.org/callback

Configuration for oxd-https-extension:

[oxd]
host = https://server.running.oxd-https-extension/
https_extension = true

[client]
authorization_redirect_uri=https://your.site.org/callback

Sample Code#

Initialization#

from oxdpython import Client

config = "/opt/yoursite/yoursite.cfg"  # This should be writable by the server
client = Client(config)

Setup Client#

This step is necessary only for sites using oxd-https-extension. The sites using oxd-server via sockets can skip setup_client() and directly register the app using register_site()

client.setup_client()

Get Client Token#

After setting up site, the client should get a protection token. This token will be cached by oxd-python as protection_access_token in the config file and passed on to the https extension as an Authentication header for each request.

client_token = client.get_client_token()

Introspect Access Token#

response = client.introspect_access_token(token['access_token'])

Register Site#

client.register_site()

Note

register_site() can be skipped since any request to the get_authorization_url() automatically registers the site.

Update Site#

client.config.set('client', 'post_logout_uri', 'https://client.example.org/post_logout')

# ensure lists are converted to comma separated string
scopes = ','.join(['openid','profile','uma_protection'])
client.config.set('client', 'scope', scopes)

client.update_site_registration()

Remove Site#

client.remove_site()

Get Authorization URL#

auth_url = client.get_authorization_url()

Get Tokens By Code#

# code = parse_callback_url_querystring()  # Refer your web framework
# state = parse_callback_url_querystring()  # Refer your web framework
tokens = client.get_tokens_by_code(code, state)

Get Access Token by Refresh Token#

new_tokens = client.get_access_token_by_refresh_token(tokens["refresh_token"])

Get User Info#

claims = client.get_user_info(tokens['access_token'])

print claims['username']
print claims['website']

Get Logout URI#

# redirect the user to this URL for logout
logout_uri = client.get_logout_uri()

UMA RS Protect#

# define the resource
resources = [{"path": "/photo",
              "conditions": [
                {
                    "httpMethods": ["GET"],
                    "scopes": ["http://photoz.example.com/dev/actions/view"]
                 }]
            }]

result = client.uma_rs_protect(resources)

RS Protect with scope_expression

resources = [{
    "path": "/photo",
    "conditions": [{
        "httpMethods": ["GET"],
        "scope_expression": {
            "rule": {
                "and": [{

                            },
                            {
                                "var": 1
                            }
                        ]
                    },
                    {
                        "var": 2
                    }
                ]
            },
            "data": [
                "http://photoz.example.com/dev/actions/all",
                "http://photoz.example.com/dev/actions/add",
                "http://photoz.example.com/dev/actions/internalClient"
            ]
        }
    }]
}]

result = client.uma_rs_protect(resources)

UMA RS Check Access#

rpt = 'lsjdfa-sfas234s'
path = '/photo'
http_method = 'GET'

response = client.uma_rs_check_access(rpt, path, http_method)

UMA Introspect RPT#

client.introspect_rpt(rpt=rpt_response['access_token'])

UMA RP Get RPT#

ticket = 'ticket obtained by app after user authorization'
rpt = client.uma_rp_get_rpt(ticket)

UMA RP Get Claims Gathering URL#

ticket = 'ticket obtained by app after user authorization'
claims_url = client.uma_rp_get_claims_gathering_url(ticket)

Tests#

oxd-python contains extensive tests for quality assurance.

  • Unit Tests can be found in tests directory and can be run using PyTest
pytest tests
  • Integration Tests need a OpenID provider and oxd-server to be setup before running and can be found in the examples/e2e_tests directory

Examples#

The examples directory contains apps and scripts written using oxd-python for OpenID Connect.
