Django OAuth Client¶

Looking for OAuth providers?

The Django client can handle OAuth 1 and OAuth 2 services. Authlib has a shared API design among framework integrations. Get started with Web OAuth Clients.

Create a registry with OAuth object:

from authlib.integrations.django_client import OAuth

oauth = OAuth()

The common use case for OAuth is authentication, e.g. let your users log in with Twitter, GitHub, Google etc.

Note

Please read Web OAuth Clients at first. Authlib has a shared API design among framework integrations, learn them from Web OAuth Clients.

Changed in version v0.13: Authlib moved all integrations into authlib.integrations module since v0.13. For earlier version, developers can import the Django client with:

from authlib.django.client import OAuth

Configuration¶

Authlib Django OAuth registry can load the configuration from your Django application settings automatically. Every key value pair can be omit. They can be configured from your Django settings:

AUTHLIB_OAUTH_CLIENTS = {
    'twitter': {
        'client_id': 'Twitter Consumer Key',
        'client_secret': 'Twitter Consumer Secret',
        'request_token_url': 'https://api.twitter.com/oauth/request_token',
        'request_token_params': None,
        'access_token_url': 'https://api.twitter.com/oauth/access_token',
        'access_token_params': None,
        'refresh_token_url': None,
        'authorize_url': 'https://api.twitter.com/oauth/authenticate',
        'api_base_url': 'https://api.twitter.com/1.1/',
        'client_kwargs': None
    }
}

We suggest that you keep ONLY client_id and client_secret in your application settings, other parameters are better in .register().

Saving Temporary Credential¶

In OAuth 1.0, we need to use a temporary credential to exchange access token, this temporary credential was created before redirecting to the provider (Twitter), we need to save this temporary credential somewhere in order to use it later.

In OAuth 1, Django client will save the request token in sessions. In this case, you just need to configure Session Middleware in Django:

MIDDLEWARE = [
    'django.contrib.sessions.middleware.SessionMiddleware'
]

Follow the official Django documentation to set a proper session. Either a database backend or a cache backend would work well.

Warning

Be aware, using secure cookie as session backend will expose your request token.

Routes for Authorization¶

Just like the example in Web OAuth Clients, everything is the same. But there is a hint to create redirect_uri with request in Django:

def login(request):
    # build a full authorize callback uri
    redirect_uri = request.build_absolute_uri('/authorize')
    return oauth.twitter.authorize_redirect(request, redirect_uri)

Auto Update Token via Signal¶

Instead of define a update_token method and passing it into OAuth registry, it is also possible to use signal to listen for token updating:

from django.dispatch import receiver
from authlib.integrations.django_client import token_update

@receiver(token_update)
def on_token_update(sender, token, refresh_token=None, access_token=None):
    if refresh_token:
        item = OAuth2Token.find(name=name, refresh_token=refresh_token)
    elif access_token:
        item = OAuth2Token.find(name=name, access_token=access_token)
    else:
        return

    # update old token
    item.access_token = token['access_token']
    item.refresh_token = token.get('refresh_token')
    item.expires_at = token['expires_at']
    item.save()

Django OpenID Connect Client¶

An OpenID Connect client is no different than a normal OAuth 2.0 client. When register with openid scope, the built-in Django OAuth client will handle everything automatically:

oauth.register(
    'google',
    ...
    server_metadata_url='https://accounts.google.com/.well-known/openid-configuration',
    client_kwargs={'scope': 'openid profile email'}
)

When we get the returned token:

token = oauth.google.authorize_access_token(request)

We can get the user information from the id_token in the returned token:

userinfo = oauth.google.parse_id_token(request, token)
