Django RESTFrame版本控制问题

1.Django 的rest_framework组件，提供了5中控制版本的方法（基于django路由系统的namespace暂未列出）:

这5个类都是继承自：BaseVersioning

from rest_framework.versioning import QueryParameterVersioning
from rest_framework.versioning import URLPathVersioning
from rest_framework.versioning import AcceptHeaderVersioning
from rest_framework.versioning import HostNameVersioning
from rest_framework.versioning import NamespaceVersioning

class BaseVersioning(object):
    default_version = api_settings.DEFAULT_VERSION
    allowed_versions = api_settings.ALLOWED_VERSIONS
    version_param = api_settings.VERSION_PARAM

    def determine_version(self, request, *args, **kwargs):
        msg = '{cls}.determine_version() must be implemented.'
        raise NotImplementedError(msg.format(
            cls=self.__class__.__name__
        ))

    def reverse(self, viewname, args=None, kwargs=None, request=None, format=None, **extra):
        return _reverse(viewname, args, kwargs, request, format, **extra)

    def is_allowed_version(self, version):
        if not self.allowed_versions:
            return True
        return ((version is not None and version == self.default_version) or
                (version in self.allowed_versions))

用法:

settings.py

REST_FRAMEWORK = {
    'DEFAULT_VERSION': 'v1',            # 默认版本
    'ALLOWED_VERSIONS': ['v1', 'v2'],   # 允许的版本
    'VERSION_PARAM': 'version'          # URL中获取值的key
}

url.py

 # 版本控制的方法，
    url(r'^test/', views.TestView.as_view(),name='test'),   # 基于url的get方法的版本控制
    url(r'^(?P<version>[v1|v2]+)/test/$', views.TestView.as_view(),name='test'),  # 版本控制，基于url的正则方式
    url(r'^test/', views.TestView.as_view(), name='test'),  # 版本控制，基于accept 请求头方式
    url(r'^test/', views.TestView.as_view(), name='test'),  # 版本控制，基于accept 请求头方式

views.py

from rest_framework.versioning import QueryParameterVersioning
from rest_framework.versioning import URLPathVersioning
from rest_framework.versioning import AcceptHeaderVersioning
from rest_framework.versioning import HostNameVersioning
from rest_framework.versioning import NamespaceVersioning

# 3.版本控制，基于accept 请求头方式方式,例如 如：Accept: application/json; version=v1 ,
    需要请求头中写入，用postman来测试，在heders中加入:Accept:application/json;version=v1

class TestView(APIView):

    versioning_class = AcceptHeaderVersioning

        reverse_url = request.versioning_scheme.reverse('test',request=request)

        print(reverse_url)

        return Response('GET请求，响应内容')

'''
# 基于主机名方法  例如:v1.example.com ,需要在settings配置ALLOWED_HOSTS = ['*']
