Birisi bu çözümle ilgileniyor ancak belirli bir süre için geçerli olan bir jetona sahip olmak istiyorsa, yeni bir jetonla değiştirilirse, işte tam çözüm (Django 1.6):
yourmodule / views.py:
import datetime
from django.utils.timezone import utc
from rest_framework.authtoken.views import ObtainAuthToken
from rest_framework.authtoken.models import Token
from django.http import HttpResponse
import json
class ObtainExpiringAuthToken(ObtainAuthToken):
def post(self, request):
serializer = self.serializer_class(data=request.DATA)
if serializer.is_valid():
token, created = Token.objects.get_or_create(user=serializer.object['user'])
utc_now = datetime.datetime.utcnow()
if not created and token.created < utc_now - datetime.timedelta(hours=24):
token.delete()
token = Token.objects.create(user=serializer.object['user'])
token.created = datetime.datetime.utcnow()
token.save()
#return Response({'token': token.key})
response_data = {'token': token.key}
return HttpResponse(json.dumps(response_data), content_type="application/json")
return HttpResponse(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
obtain_expiring_auth_token = ObtainExpiringAuthToken.as_view()
yourmodule / urls.py:
from django.conf.urls import patterns, include, url
from weights import views
urlpatterns = patterns('',
url(r'^token/', 'yourmodule.views.obtain_expiring_auth_token')
)
projeniz url.py (urlpatterns dizisinde):
url(r'^', include('yourmodule.urls')),
yourmodule / authentication.py:
import datetime
from django.utils.timezone import utc
from rest_framework.authentication import TokenAuthentication
from rest_framework import exceptions
class ExpiringTokenAuthentication(TokenAuthentication):
def authenticate_credentials(self, key):
try:
token = self.model.objects.get(key=key)
except self.model.DoesNotExist:
raise exceptions.AuthenticationFailed('Invalid token')
if not token.user.is_active:
raise exceptions.AuthenticationFailed('User inactive or deleted')
utc_now = datetime.datetime.utcnow()
if token.created < utc_now - datetime.timedelta(hours=24):
raise exceptions.AuthenticationFailed('Token has expired')
return (token.user, token)
REST_FRAMEWORK ayarlarınızda, TokenAuthentication yerine ExpiringTokenAuthentication'ı Authentification sınıfı olarak ekleyin:
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': (
'rest_framework.authentication.SessionAuthentication',
#'rest_framework.authentication.TokenAuthentication',
'yourmodule.authentication.ExpiringTokenAuthentication',
),
}
