Django rest framework post requests gets Forbidden (CSRF cookie not set.)

Question

I'm trying to do some post requests to my Django project using DRF but it gives me this error : Forbidden (CSRF cookie not set.) .. here is my code :

serializers.py

from django.contrib.auth.models import User


class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        fields = ['username','password','id']

views.py

class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer

urls.py

router.register(r'main_users', UserViewSet)
urlpatterns = [
    path('api/', include(router.urls)),
