python - DRF auth_token : "non_field_errors": [ "Unable to log in with provided credentials."

Question

为 Django 编写的两个 JWT 包都给我带来了文档质量差的问题，所以我尝试了 DRF-auth_token 包。这是我遵循的一个很好的例子，Django Rest Framework Token Authentication .理论上你应该能够去

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 token 不起作用，所以我自己重写了它以使其起作用:

@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": "thisguy@example.com", "password": "wombat"}
-->
{
  "token": "292192b101153b7ced74dd52deb6b3df22ef2c74"
}

DRF auth_token 不起作用:

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

设置.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',
    )
}

看起来设置正确。我数据库中的每个用户都有一个 token 。每个用户在数据库中都是is_authenticated 和is_active。 super 用户可以获得他们的 token :

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

出于某种原因，只有 super 用户才能获得 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取他们的 token ？谢谢

• 我在尝试使用此 API 端点时遇到了相同的错误消息:
  来自 rest_framework.authtoken.views 的“obtain_auth_token”类，
  但是惊喜!问题是 User serializer 在第一名 ! .

• 用户是使用 API endppint 创建的，他们的密码被保存为纯文本!，如以下屏幕截图所示: User Database
  但是 TokenAPI 端点加密了密码，所以从那里来了冲突! ,

• 我已经更改了 User Serializer 类 并覆盖了 create 函数以使用对密码进行哈希处理的 set_password 函数:

  class UserSerializer(serializers.ModelSerializer):
      class Meta:
          model = User
          fields = ['email', 'username', 'password']
          extra_kwargs = {'password': {'write_only': True}}
  
      def create(self, validated_data):
          user = User(
              email=validated_data['email'],
              username=validated_data['username']
          )
          user.set_password(validated_data['password'])
          user.save()
          return user
  

• 现在我已经编辑了我的用户序列化器，数据存储如下: User database after modification

• 因此错误:“non_field_errors”: [“无法使用提供的凭据登录。” 停止显示! ，并且 token API 端点“localhost:8000/api-token-auth/”有效!
