请求进来 封装request. 版本限制 认证 权限 节流

版本

self.version_param url中版本的key

self.default_version

self.is_allowed_version

都是写在配置文件中    如果是默认就是?version=

reverse

获取版本

print(request.version)

获取处理版本的对象

print(request.versioning_scheme)

REST_FRAMEWORK = {

    "DEFAULT_VERSION":'v1',

    "ALLOWED_VERSIONS": ['v1','v2'] ,

    "VERSION_PARAM":'version',

}

    URL中通过get的方式获取

        自定义

        from django.shortcuts import render,HttpResponse

        from rest_framework.views import APIView

        from rest_framework.request import Request

        # Create your views here.

        class ParamVersion(object):

            def determine_version(self, request, *args, **kwarags):

                version = request.query_params.get('version')

                return version

        class UsersView(APIView):

            versioning_class = ParamVersion

            def get(self,request, *args, **kwargs):

                # version = request._request.GET.get('version')

                # print(version)

                print(request.version)

                return HttpResponse('用户列表')

    在路径中传参

常用方式

views.py

from django.shortcuts import render,HttpResponse

from rest_framework.versioning import QueryParameterVersioning,URLPathVersioning

class UsersView(APIView):

    versioning_class = URLPathVersioning

    def get(self,request, *args, **kwargs):

        print(request.version)

        return HttpResponse('用户列表')

cmdb 下的 urls.py

from django.conf.urls import url,include

from cmdb import views

urlpatterns = [

    url(r'^(?P<version>[v1|v2]+)/users/$',views.UsersView.as_view())

]

全局使用时   推荐使用的方式

setting文件

REST_FRAMEWORK = {

    "DEFAULT_VERSIONING_CLASS":"rest_framework.versioning.URLPathVersioning"

    "DEFAULT_VERSION":'v1',

    "ALLOWED_VERSIONS": ['v1','v2'] ,

    "VERSION_PARAM":'version',

}

views.py文件

from django.shortcuts import render,HttpResponse

class UsersView(APIView):

    def get(self,request, *args, **kwargs):

        print(request.version)

        return HttpResponse('用户列表')

urls.py文件 cmdb下的

urlpatterns = [

    url(r'^(?P<version>[v1|v2]+)/users/$',views.UsersView.as_view())

]

总结：

    使用：

        配置文件：

        REST_FRAMEWORK = {

                        "DEFAULT_VERSIONING_CLASS":"rest_framework.versioning.URLPathVersioning"

                        "DEFAULT_VERSION":'v1',

                        "ALLOWED_VERSIONS": ['v1','v2'] ,

                        "VERSION_PARAM":'version',

                    }

        路由系统

        urlpatterns = [

                        url(r'^(?P<version>[v1|v2]+)/users/$',views.UsersView.as_view())

                    ]

        主路由

        from django.conf.urls import url,include

        urlpatterns = [

                        path('admin/', admin.site.urls),

                        url(r'^cmdb/',include('cmdb.urls'))

        ]

        视图中

        from django.shortcuts import render,HttpResponse

        from rest_framework.views import APIView

        from django.urls import reverse

        from rest_framework.request import Request

        # Create your views here.

        class UsersView(APIView):

            #反向生成URL

            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)

                #通过rest_framework反向生成URL

                u1 = request.versioning_scheme.reverse(viewname='user',request=request)

                print(u1)

                #通过原生Django反向生成URL

                u2 = reverse(viewname='user',kwargs={'version':})

                print(u2)

                return HttpResponse('用户列表')
