标签：self 配置 token filter nfa username field 需求 first
在需要认证的视图类里加上authentication_classes = [认证组件1类名,认证组件2类名....]
示例如下：
seralizers.py
from rest_framework import serializers
from app01 import models
class PublishSerializers(serializers.ModelSerializer):
class Meta:
model = models.Publish
fields = ‘__all__‘
auth.py
from rest_framework.authentication import BaseAuthentication
from rest_framework import exceptions
from app01 import models
class TokenAuth(BaseAuthentication):
def authenticate(self,request):
‘‘‘函数名必须叫authenticate‘‘‘
# 验证条件根据需求设置（此示例为需要有token值）
token = request.GET.get(‘token‘)
token_obj = models.Token.objects.filter(token=token).first()
if not token_obj:
# 如果验证失败，需要跑出AuthenticationFailed错误
raise exceptions.AuthenticationFailed("验证失败!")
else:
user = token_obj.user
# 如果验证成功，需要返回一个元组，分别是用户以及验证类的实例对象，然后内部会赋值给request.user和request.auth
return user.username,token_obj
views.py
from rest_framework import viewsets
from app01.auth import TokenAuth
class PublishViewSet(viewsets.ModelViewSet):
# 在这里配置authentication_classes
# 注意，值为一个列表，可以放多个认证组件类名
authentication_classes = [TokenAuth]
queryset = models.Publish.objects.all()
serializer_class = serializer.PublishSerializers
在setting.py里配置如下：
REST_FRAMEWORK = {
"DEFAULT_AUTHENTICATION_CLASSES": ["app01.auth.TokenAuth",]
}
这样配置之后，每个视图类都要经过认证成功之后才能执行，
