# app/views.py

from django.utils.translation import ugettext_lazy as _
from rest_framework_simplejwt.serializers import TokenObtainPairSerializer
from rest_framework_simplejwt.views import TokenObtainPairView

class MyTokenObtainPairSerializer(TokenObtainPairSerializer):

    default_error_messages = {
        'no_active_account': _('email or password is incorrect!')
    }

class MyTokenObtainPairView(TokenObtainPairView):
    serializer_class = MyTokenObtainPairSerializer

然后，使用MyTokenObtainPairView，其中使用TokenObtainPairView，e。例如：

# app/urls.py

from app.views import MyTokenObtainPairView

urlpatterns = [
  ...
  path('auth/token/', MyTokenObtainPairView.as_view())
  ...
]

创建自定义Login视图，该视图接受用户名和密码，并根据给定的凭据进行身份验证，然后返回访问权限，并在用户通过身份验证时刷新令牌

from rest_framework_simplejwt.tokens import RefreshToken
from django.contrib.auth import authenticate

def get_tokens_for_user(user):
   refresh = RefreshToken.for_user(user)

   return {
     'refresh': str(refresh),
     'access': str(refresh.access_token),
   }

class LoginView(APIView):
   def post(self,request):
       username= request.data["username"]
       password = request.data["password"]

       user = authenticate(username=username,password=password)
       if user:
           return Response(get_tokens_for_user(user))
       return Response({"error":"email or password isincorrect!"},status=status.HTTP_203_NON_AUTHORITATIVE_INFORMATION)
