RESTFUL认证流程

方法一：

    class Myauthentication(object):
        def authenticate(self, request):
             token = request._request.GET.get('token')
             if token and token == '123':
                 return ('lisi', token)
            else:
                raise AuthenticationFailed('认证失败')

        def authenticate_header(self, request):#不写这个方法会报这个方法错
            pass

方法二:

    from rest_framework.authentication import BaseAuthentication
    class Myauthentication(BaseAuthentication):
        def authenticate(self, request):
              token = request._request.GET.get('token')
              if token and token == '123':
                  return ('lisi', token)
            else:
                  raise AuthenticationFailed('认证失败')

!!两种方法写完后 需要调用认证方法类

    authentication_classes = [Myauthentication,]#调用认证类方法
    #调用方式
