rest_framework-版本-总结完结篇

总urls.py

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

分流后urls.py

from django.conf.urls import url
from api import views
urlpatterns = [
    url(r'^(?P<version>[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, HttpResponse
from rest_framework.views import APIView
from rest_framework.versioning import QueryParameterVersioning,URLPathVersioning
from 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={'version':1212})
        print(u2)
        return HttpResponse('ok')
