DRF auth_token:"non_field_errors":[“无法使用提供的凭据登录." [英] DRF auth_token: "non_field_errors": [ "Unable to log in with provided credentials."

问题描述

两个为Django编写的JWT软件包都给我带来了文档质量不佳的问题，因此我尝试使用DRF-auth_token软件包.这是我遵循的一个很好的示例， Django Rest Framework令牌认证.从理论上讲，您应该可以进入

Both JWT packages written for Django gave me issues with poor documentation, so I try DRF-auth_token package. This is a good example I followed, Django Rest Framework Token Authentication. You should in theory be able to go to

localhost:8000/api-token-auth/

urls.py:

from django.conf.urls import url, include
from django.contrib import admin
from django.contrib.auth.models import User
from rest_framework.authtoken import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^api/', include('api.urls', namespace='api')),
    url(r'^orders/', include('orders.urls', namespace='orders')),
    url(r'^api-token-auth/', views.obtain_auth_token, name='auth-token'),

]

为用户获取令牌无法正常工作，因此我自己重写了令牌以使其正常工作:

Getting a token for users is not working so I have rewritten it myself to make it work:

@api_view(['POST'])
def customer_login(request):
    """
    Try to login a customer (food orderer)
    """
    data = request.data

    try:
        username = data['username']
        password = data['password']
    except:
        return Response(status=status.HTTP_400_BAD_REQUEST)

    try:
        user = User.objects.get(username=username, password=password)
    except:
        return Response(status=status.HTTP_401_UNAUTHORIZED)

    try:
        user_token = user.auth_token.key
    except:
        user_token = Token.objects.create(user=user)

    data = {'token': user_token}
    return Response(data=data, status=status.HTTP_200_OK)

我的版本有效:

http://localhost:8000/api/login/customer-login/
{"username": "[e-mail]", "password": "wombat"}
-->
{
  "token": "292192b101153b7ced74dd52deb6b3df22ef2c74"
}

DRF auth_token不起作用:

The DRF auth_token does not work:

http://localhost:8000/api-token-auth/
{"username": "[e-mail]", "password": "wombat"}
-->
{
  "non_field_errors": [
    "Unable to log in with provided credentials."
  ]
}

settings.py

settings.py

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    # third party:
    'django_extensions',
    'rest_framework',
    'rest_framework.authtoken',



REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.IsAuthenticated',
    ),
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.TokenAuthentication',
    )
}

似乎设置正确.我数据库中的每个用户都有一个令牌. DB中的每个用户都是is_authenticated和is_active.超级用户可以获得其令牌:

It seems set up correctly. Every user in my DB has a token. Each user is is_authenticated and is_active in DB. Super users can get their token:

localhost:8000/api-token-auth/
{"username": "mysuperuser", "password": "superuserpassword"}
-->
{
  "token": "9297ff1f44dbc6caea67bea534f6f7590d2161b0"
}

由于某些原因，只有超级用户才能获得令牌:

for some reason, only super user can get a token:

localhost:8000/api-token-auth/
{"username": "regularguy", "password": "password"}
-->
{
  "non_field_errors": [
    "Unable to log in with provided credentials."
  ]
}

为什么我的用户无法登录并获得其令牌?谢谢

Why can't my users log in and get their token? Thank you

推荐答案

我从

I went ahead and did this from the drf token auth docs and didn't run into any problems with superusers, staffusers, or normal users.

也请尝试遵循官方文档的步骤而不是该SO答案，看看是否可以解决问题-可能有所更改.

Also try following the steps of the official docs instead of that SO answer and see if that fixes the problem - it's possible something changed.

这是我采取的一般步骤:

Here were the general steps I took:

• 安装django，drf
• 在INSTALLED_APPS中放入"rest_framework"和"rest_framework.authtoken"
• 在我的rest_framework设置中添加"TokenAuthentication"
• 运行迁移
• 为用户创建令牌(我刚刚在urls.py中做到了)
• 创建令牌的网址
• POST http://localhost:8000/token/ {用户名":"... ，" password:" ...}

• install django, drf
• put 'rest_framework' and 'rest_framework.authtoken' in INSTALLED_APPS
• add 'TokenAuthentication' in my rest_framework settings
• run migrate
• create tokens for users (I just did this in urls.py)
• create the url for token
• POST http://localhost:8000/token/ {"username": "...", "password": "..."}

如果您在任何地方公开代码，我将很高兴进一步查看并发现我的发现.

If you have the code public anywhere I'd be glad to take a further look and see what I find.
