Authentication infromation is not provided when I use Django rest framework

Question

I use the Django Rest Framework, but there seems I can not access, need permission to do this:

Authentication infromation is not provided.

How to resolve this issue?

EDIT -1

My code in my views.py:

@api_view(['GET', 'POST'])
def task_list(request):
    '''
    List all tasks, or create a new task.
    '''
    if request.method == 'GET':
        tasks = Task.objects.all()
        serializer = TaskSerializer(tasks, many=True)
        return Response(serializer.data)
    elif request.method == 'POST':
        serializer = TaskSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        else:
            return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)


# detail
@api_view(['GET', 'PUT', 'DELETE'])
def task_detail(request, pk):
    try:
        task = Task.objects.get(pk=pk)
    except Task.DoesNotExist:
        return Response(status=status.HTTP_404_NOT_FOUND)

    if request.method == 'GET':
        serializer = TaskSerializer(task)
        return Response(serializer.data)
    elif request.method == 'PUT':
        serializer = TaskSerializer(task, data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)
        else:
            return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
    elif request.method == 'DELETE':
        task.delete()
        return Response(status=status.HTTP_204_NO_CONTENT)

Just incase you are still developing its better if you set the authentication class to allow allow any.. then change it whenever it is needed...

'DEFAULT_PERMISSION_CLASSES': (
   'rest_framework.permissions.AllowAny',
)

hope that helps..
