总urls.py

from django.conf.urls import url, includeurlpatterns = [    url(r'^api/', include('api.urls'))]

 

分流后urls.py

from django.conf.urls import urlfrom api import viewsurlpatterns = [    url(r'^(?P
     
      [v1|v2]+)/user/$', views.UserView.as_view(),name='us')]
     

 

settings.py

REST_FRAMEWORK = {    "DEFAULT_VERSIONING_CLASS":"rest_framework.versioning.URLPathVersioning",    "DEFAULt_VERSION":'v1',  #默认为1    "ALLOWED_VERSIONS":['v1','v2'], #仅允许v1或者v2访问    "VERSION_PARAM":'version',}

views.py 视图

from django.shortcuts import render, HttpResponsefrom rest_framework.views import APIViewfrom rest_framework.versioning import QueryParameterVersioning,URLPathVersioningfrom django.urls import reverse# Create your views here.class UserView(APIView):    def get(self, request, *args, **kwargs):        #获取版本        print(request.version)        #获取处理版本的对象        print(request.versioning_scheme)        #反向生成URL（rest_framework）        u1 = request.versioning_scheme.reverse(viewname='us',request=request)        print(u1)        u2 = reverse(viewname='uuu', kwargs={
