django-oauth-toolkit：自定义身份验证响应

Question

我是Django OAuth Toolkit的新手。我想自定义身份验证响应。

我在Django应用程序上的身份验证URL配置是：

url('authenticate/',
    include('oauth2_provider.urls', namespace='oauth2_provider'))

https://django-oauth-toolkit.readthedocs.io/zh-CN/latest/install.html

现在，当我启动此命令时：

curl -X POST -d 'grant_type=password&username=$username&password=$password'
 -u "$client_id:$client_secret" http://127.0.0.1:8000/authenticate/token/

我得到这个回应：

{
   "access_token": "ATiM10L0LNaldJPk12drXCjbhoeDR8",
   "expires_in": 36000,
   "refresh_token": "II4UBhXhpVDEKWmsUQxDzkj3OMjW1p",
   "scope": "read groups write",
   "token_type": "Bearer"
}

并希望此响应：

{
   "access_token": "ATiM10L0LNaldJPk12drXCjbhoeDR8",
   "expires_in": 36000,
   "refresh_token": "II4UBhXhpVDEKWmsUQxDzkj3OMjW1p",
   "scope": "read groups write",
   "token_type": "Bearer",
   "member": {
      "id": 1,
      "username": "username",
      "email": "email@gmail.com",
      ....
   }
}

我只想覆盖此响应，以添加已认证用户的信息。我已经阅读了django-oauth-toolkit的文档。而且我没有找到解决问题的办法...

我可以通过覆盖您的views.py中的TokenView类来进行此更改

from django.http import HttpResponse
from oauth2_provider.views.base import TokenView
from django.utils.decorators import method_decorator
from django.views.decorators.debug import sensitive_post_parameters
from oauth2_provider.models import get_access_token_model, get_application_model
from oauth2_provider.signals import app_authorize

class CustomTokenView(TokenView):
    @method_decorator(sensitive_post_parameters("password"))
    def post(self, request, *args, **kwargs):
        url, headers, body, status = self.create_token_response(request)
        if status == 200:
            body = json.loads(body)
            access_token = body.get("access_token")
            if access_token is not None:
                token = get_access_token_model().objects.get(
                    token=access_token)
                app_authorized.send(
                    sender=self, request=request,
                    token=token)
                body['member'] = {
                    'id': token.user.id, 
                    'username': token.user.username, 
                    'email': token.user.email
                }
                body = json.dumps(body) 
        response = HttpResponse(content=body, status=status)
        for k, v in headers.items():
            response[k] = v
        return response

在urls.py中，只需指向自定义视图覆盖令牌url。此导入应在django-oauth-toolkit的包含之前进行

url(r"authenticate/token/$", CustomTokenView.as_view(), name="token"),
url('authenticate/',
    include('oauth2_provider.urls', namespace='oauth2_provider'))

现在，退货将包含会员数据

  {
    "access_token": "YtiH9FGwAf7Cb814EjTKbv3FCpLtag", 
    "expires_in": 36000, 
    "token_type": "Bearer", 
    "scope": "read write groups", 
    "refresh_token": "99TyWmCwELrJvymT8m6Z9EPxGr3PJi", 
    "member": {
        "id": 1, 
        "username": "admin", 
        "email": "admin@admin.com"
     }
  }
