Resource Server

Protect users resources, so that only the authorized clients with the authorized access token can access the given scope resources.

A resource server can be a different server other than the authorization server. Here is the way to protect your users’ resources in Django:

from authlib.integrations.django_oauth2 import ResourceProtector, BearerTokenValidator
from django.http import JsonResponse

require_oauth = ResourceProtector()
require_oauth.register_token_validator(BearerTokenValidator(OAuth2Token))

@require_oauth('profile')
def user_profile(request):
    user = request.oauth_token.user
    return JsonResponse(dict(sub=user.pk, username=user.username))

If the resource is not protected by a scope, use None:

@require_oauth()
def user_profile(request):
    user = request.oauth_token.user
    return JsonResponse(dict(sub=user.pk, username=user.username))

# or with None

@require_oauth(None)
def user_profile(request):
    user = request.oauth_token.user
    return JsonResponse(dict(sub=user.pk, username=user.username))

The decorator require_oauth will add an oauth_token property on request, which is the instance of current in-use Token.

Multiple Scopes

Changed in version v1.0.

You can apply multiple scopes to one endpoint in AND, OR and mix modes. Here are some examples:

@require_oauth(['profile email'])
def user_profile(request):
    user = request.oauth_token.user
    return JsonResponse(dict(sub=user.pk, username=user.username))

It requires the token containing both profile and email scope.

@require_oauth(['profile', 'email'])
def user_profile(request):
    user = request.oauth_token.user
    return JsonResponse(dict(sub=user.pk, username=user.username))

It requires the token containing either profile or email scope.

It is also possible to mix AND and OR logic. e.g.:

@app.route('/profile')
@require_oauth(['profile email', 'user'])
def user_profile(request):
    user = request.oauth_token.user
    return JsonResponse(dict(sub=user.pk, username=user.username))

This means if the token will be valid if:

  1. token contains both profile and email scope

  2. or token contains user scope

Optional require_oauth

There is one more parameter for require_oauth which is used to serve public endpoints:

@require_oauth(optional=True)
def timeline_api(request):
    if request.oauth_token:
        return get_user_timeline(request.oauth_token.user)
    return get_public_timeline(request)
