APIView继承自View,并对其进行了包装成高阶Request。Request中传入了更多参数,如权限认证。函数
我接着在API View 执行initial函数时,会对request进行验证,确保来访的请求是被容许的。学习
咱们能够经过继承APIView,重写其 authentication_classes 属性,来自定义认证器,如验证请求中是否含有token字段!spa
from rest_framework.views import APIView
from rest_framework.authentication import BaseAuthentication
from rest_framework.exceptions import NotAuthenticated
class MyUser(object):
is_authenticated = True
class MyAuthentication(object):
def authenticate(self, request):
token = request._request.GET.get('token')
if not token:
raise NotAuthenticated()
return (MyUser,None)
def authenticate_header(self, val):
pass
