有两种方法添加验证

• 全局验证
• 局部验证

• rest_framework 默认的验证是
  • 导包地址是

from rest_framework.authentication import BaseAuthentication,BasicAuthentication, SessionAuthentication, TokenAuthentication
   1.     BasicAuthentication: 基于用户名密码
   2.     SessionAuthentication：基于session
   3.     TokenAuthentication：基于token

全局验证添加方法

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.BasicAuthentication',
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.TokenAuthentication',
    ),
}

• 局部验证添加方法

 authentication_classes = [
        MyAuthentication
    ]

自定义验证

1. 新建一个 Authentication文件
2. 创建一个类继承 BaseAuthentication

class MyAuthentication(BaseAuthentication):
    def authenticate(self,request):
        token = request.META.get('HTTP_TOKEN')

        obj = UserToken.objects.filter(token=token).first()
        if not obj:
            raise exceptions.AuthenticationFailed('请检查你的token')
        else:
            return (obj.user,obj)
