我尝试过此代码(此链接之后:How can we assign different expiry time to different users in jwt tokens in django)。这段代码更新了刷新令牌的到期时间,但是我想使用simplejwt模块在django中更新访问令牌的到期时间。请提出任何建议。
答案 0 :(得分:4)
我快速浏览了simplejwt github的页面,您可以在settings.py
文件中自定义一些settings;
SIMPLE_JWT = {
'ACCESS_TOKEN_LIFETIME': timedelta(minutes=5),
}
根据评论更新答案
感谢您的回应。但是我想全局设置jwt的到期时间,然后根据角色设置,我想覆盖该到期时间。怎么可能??
正如您所说,您必须覆盖默认的令牌生成器方法。但是如何?
首先,创建您自己的令牌获取视图(继承自TokenObtainPairView
)和您自己的令牌获取序列化程序(继承自TokenObtainPairSerializer
)。之后,您可以看到validate
方法创建了access
和refresh
令牌,因此,如果要基于用户角色等创建令牌,则也必须覆盖该方法。还必须更改您的urls.py
。
示例;
import datetime
from django.utils.six import text_type
from rest_framework_simplejwt.views import TokenObtainPairView
from rest_framework_simplejwt.serializers import TokenObtainPairSerializer
SUPERUSER_LIFETIME = datetime.timedelta(minutes=1)
class MyTokenObtainSerializer(TokenObtainPairSerializer):
def validate(self, attrs):
data = super(TokenObtainPairSerializer, self).validate(attrs)
refresh = self.get_token(self.user)
data['refresh'] = text_type(refresh)
if self.user.is_superuser:
new_token = refresh.access_token
new_token.set_exp(lifetime=SUPERUSER_LIFETIME)
data['access'] = text_type(new_token)
else:
data['access'] = text_type(refresh.access_token)
return data
class MyTokenObtainView(TokenObtainPairView):
serializer_class = MyTokenObtainSerializer
urls.py
urlpatterns = [
path('api/token/', MyTokenObtainView.as_view(), name='token_obtain_pair')
]
