使用DOT的带有oAuth2的Django DRF（Djangoauthttoolkit）

Question

我试图使DRF与oAuth2（django oauth工具包）一起工作。

我在关注http://httplambda.com/a-rest-api-with-django-and-oauthw-authentication/

首先，我遵循了该指令，但随后，在获得身份验证错误后，我设置了此演示：https://github.com/felix-d/Django-Oauth-Toolkit-Python-Social-Auth-Integration

结果相同：我无法使用此curl生成访问令牌：

curl -X POST -d "grant_type=password&username=<user_name>&password=<password>" -u "<client_id>:<client_secret>" http://127.0.0.1:8000/o/token/

我得到这个错误：

{"error": "unsupported_grant_type"}

oAuth2应用程序设置为grant_type password。我将grant_type更改为“client credentials”，并尝试了此curl：

curl -X POST -d "grant_type=client_credentials" -u "<client_id>:<client_secret>" http://127.0.0.1:8000/o/token/

这起作用，我得到了生成的身份验证令牌。

在那之后，我试着要一份所有啤酒的清单：

curl -H "Authorization: Bearer <auth_token>" http://127.0.0.1:8000/beers/

我得到的答复是：

{"detail":"You do not have permission to perform this action."}

这是views.py的内容，它应该显示啤酒：

from beers.models import Beer
from beers.serializer import BeerSerializer
from rest_framework import generics, permissions

class BeerList(generics.ListCreateAPIView):
    serializer_class = BeerSerializer
    permission_classes = (permissions.IsAuthenticated,)

    def get_queryset(self):
        user = self.request.user
        return Beer.objects.filter(owner=user)

    def perform_create(self, serializer):
        serializer.save(owner=self.request.user)

我不知道这里有什么问题。首先是“未报告的授权类型”，然后是其他curl调用。当我在django oauth工具包中做基础教程时，这也发生在我身上。我用的是Django 1.8.2和python3.4

谢谢你的帮助！
