cli-oauth2 0.3.1

Helper library for OAuth2 in command-line tools

CLI OAuth2

This Python library help command-line tool authors to use OAuth2 services. Built using requests-oauthlib with parts of google_auth_oauthlib.

Installation

pip install cli-oauth2

Usage

Do something like this:

from oauthcli import OpenStreetMapAuth

auth = OpenStreetMapAuth(
    client_id, secret_id, ['read_prefs']
).auth_server(token_test=lambda r: r.get('user/details'))

data = auth.get('user/details.json')
if data.status_code != 200:
    print(f'Error {data.status_code}: {data.text})')
else:
    print(f'Hello, {data.json()["user"]["display_name"]}')

Tokens are saved to disk, so subsequent runs won't require authorization.

Auth objects have these methods and properties:

• auth_server() opens a web browser and catches the response by starting a local server.
• auth_code() opens a web browser and expected a user to copy the code presented by the provider. It uses urn:ietf:wg:oauth:2.0:oob redirect uri.
• authorized returns whether there is an active access token.
• get, post etc call the relevant requests methods, but often shadow the server name. See the example above.
• session is the underlying OAuth2Session object.

There are some predefined providers:

• OpenStreetMapAuth
• OpenStreetMapDevAuth
• GoogleAuth
• GitHubAuth
• MastodonAuth (requires a server parameter)
• RedditAuth
• FacebookAuth
• LinkedInAuth

Note that only OSM and GitHub providers were tested. I welcome pull requests with fixes.

If you need to use another provider, just subclass AuthFlow and pass it provider_id (the key for the stored token map), OAuth2Session(client_id, scope=scopes), auth_url, token_url, and client_secret.

Cleanup

The tool stores tokens in a json in the configuration directory. To clean some or all tokens, use the oauthclean command-line tool.
