如何在Django中返回带有令牌的用户ID? [英] How can I return user ID with token in Django?

问题描述

我使用Django中的默认视图生成令牌:

I generate tokens using default view in Django:

url(r'^login/', rest_auth_views.obtain_auth_token),

我有一个问题，因为我的前端不知道当前登录的用户ID是什么.

I have a problem because my front-end doesn't know what is the currently logged in user ID.

我应该用令牌返回它还是创建另一个请求?

Should I return it with token or maybe create some another request?

我知道有很多不同的方法，但是我想选择最佳的解决方案.

I know that there is a lot of different ways, but I would like to choose the most optimal solution.

推荐答案

您可以覆盖rest_framework.authtoken.views.ObtainAuthToken.post以获得所需的结果.

You could override rest_framework.authtoken.views.ObtainAuthToken.post in order to get the result you want.

myapp/views.py

from rest_framework.authtoken.views import ObtainAuthToken
from rest_framework.authtoken.models import Token
from rest_framework.response import Response


class CustomObtainAuthToken(ObtainAuthToken):
    def post(self, request, *args, **kwargs):
        response = super(CustomObtainAuthToken, self).post(request, *args, **kwargs)
        token = Token.objects.get(key=response.data['token'])
        return Response({'token': token.key, 'id': token.user_id})

myapp/urls.py

from django.conf.urls import url

from .views import CustomObtainAuthToken

urlpatterns = [
    url(r'^authenticate/', CustomObtainAuthToken.as_view()),
]

样本结果

$ http :8000/authenticate/ username=someuser password=secretpassword
HTTP/1.0 200 OK
Allow: POST, OPTIONS
Content-Language: en
Content-Type: application/json
Date: Tue, 22 Mar 2017 18:30:10 GMT
Server: WSGIServer/0.2 CPython/3.5.1
Vary: Accept-Language, Cookie
X-Frame-Options: SAMEORIGIN

{
    "id": 16, 
    "token": "82e0bc9980a6b2c9a70969b0f8dc974418dda399"
}

这里的想法是重写ObtainAuthToken视图类的post方法.在这里，我要做的就是调用父类以获取令牌，然后查找该令牌以找到关联的用户ID.

The idea here is to override the post method of the ObtainAuthToken view class. Here all I have done is call the parent class to get the token, then look up that token to find the associated user id.
