执行过程 APIView() Ruquest() Authentication() OrderView()
APIView()
    def duspatch:

        self.initial(request)

    def inital():
        self.perform_authticate()

    def perform_authticate():
        request.user


Ruquest()
    @
    def user()
    ‘‘‘

    def _authenticate()
        循环所有authenticatior对象
        执行对象的authenticate方法

Authentication 自定义认证类

    def authenticate():
        自定义认证类
            -报错 raise exceptions.AuthenticationFailed("用户认证失败")
            -返回元组(user对象， token对象)

            print(request.user, request.auth)

OrderView
    authentication_classes = [Authtication,]

    def get():
        ...

    def post()
        ...

Settinfs   #全局使用#在api目录下创建个utils目录 创建个auth.py文件  将FirstAuthentication()添加
    REST_FRAMEWORK = {
        "DEFAULT_AUTHENTICATION_CLASSES":[‘api.utils.auth.FirstAuthentication‘],
        "UNAUTHENTICATED_USER":lambda:"匿名用户",  #request.user 匿名用户的返回值
        "UNAUTHENTICATED_USER":lambda:"None"  #request.user 匿名用户的返回值为空
        "UNAUTHENTICATED_TOKEN":lambda:"None"  #request.auth 匿名用户的返回值为空
    }

局部不使用
class AuthView(APIView):
    authentication_class = []
    def get(self,request, *args, **kwargs):
        pass


内置的认证类
authentication.py文件中有以下几个类 BaseAuthentication(object)
class BaseAuthentication(object):
    def authenticate(self,request)
    def authenticate_header(self, request)  #认证失败的话 给浏览器返回的相应头饿
        return ‘Basic realm="%s"‘ % self.www_authenticate_realm
BasicAuthentication(BaseAuthentication) #是浏览器实现的 浏览器将用户和密码发给服务器
SessionAuthntication(BaseAuthentication) #不用
TokenAuthtication(BaseAuthntication) #不用
RemoteUserAuthentication(BaseAuthentication) #不用

暂时只用BaseAuthentication  创建类 继承BaseAuthentication
from rest_framework.authentication import BaseAuthentication
class FirstAuthentication(BaseAuthentication):
    def authenticate(self, request):
        pass
    #这样就可以实现认证功能了
