Using the URLconf defined in mysite.urls, Django tried these URL

patterns, in this order:

^admin/
^employees/

The empty path didn't match any of these.

from django.conf.urls import url
from django.contrib import admin
from webapp import views
from django.urls import path
from rest_framework.urlpatterns import format_suffix_patterns


urlpatterns = [

url(r'^admin/', admin.site.urls),
url(r'^employees/', views.employeeList.as_view()),
]

class employeeList(APIView):

def get(self, request):
    employees1 = employees.objects.all()
    serializer = employeesSerializer(employees1, many=True)

    return Response(serializer.data)

def post(self):
    pass
