简单使用
-drf版本控制
-在setting中配置
'DEFAULT_VERSION': 'v1', # 默认版本(从request对象里取不到，显示的默认值)
'ALLOWED_VERSIONS': ['v1', 'v2'], # 允许的版本
'VERSION_PARAM': 'version' # URL中获取值的key
-局部使用
versioning_class = URLPathVersioning
-全局使用
'DEFAULT_VERSIONING_CLASS':'rest_framework.versioning.URLPathVersioning',
内置的版本控制类
from rest_framework.versioning import QueryParameterVersioning,AcceptHeaderVersioning,NamespaceVersioning,URLPathVersioning #基于url的get传参方式：QueryParameterVersioning------>如：/users?version=v1
#基于url的正则方式：URLPathVersioning------>/v1/users/
#基于 accept 请求头方式：AcceptHeaderVersioning------>Accept: application/json; version=1.0
#基于主机名方法：HostNameVersioning------>v1.example.com
#基于django路由系统的namespace：NamespaceVersioning------>example.com/v1/users/
局部使用
#在CBV类中加入
versioning_class = URLPathVersioning
全局使用
REST_FRAMEWORK = {
'DEFAULT_VERSIONING_CLASS':'rest_framework.versioning.QueryParameterVersioning',
'DEFAULT_VERSION': 'v1', # 默认版本(从request对象里取不到，显示的默认值)
'ALLOWED_VERSIONS': ['v1', 'v2'], # 允许的版本
'VERSION_PARAM': 'version' # URL中获取值的key
}
示例
基于正则的方式：
url
from django.conf.urls import url, include
from web.views import TestView urlpatterns = [
url(r'^(?P<version>[v1|v2]+)/test/', TestView.as_view(), name='test'),
]
views.py
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.versioning import URLPathVersioning class TestView(APIView):
versioning_class = URLPathVersioning def get(self, request, *args, **kwargs):
# 获取版本
print(request.version)
# 获取版本管理的类
print(request.versioning_scheme) # 反向生成URL
reverse_url = request.versioning_scheme.reverse('test', request=request)
print(reverse_url) return Response('GET请求，响应内容')
# 基于django内置,反向生成url
from django.urls import reverse
url2=reverse(viewname='ttt',kwargs={'version':'v2'})
print(url2)
源码分析
#执行determine_version，返回两个值，放到request对象里
version, scheme = self.determine_version(request, *args, **kwargs)
request.version, request.versioning_scheme = version, scheme def determine_version(self, request, *args, **kwargs):
#当配置上版本类之后，就会实例化
if self.versioning_class is None:
return (None, None)
scheme = self.versioning_class()
return (scheme.determine_version(request, *args, **kwargs), scheme)
