四、版本控制

4.1 自定义版本控制类

• settings.py

  # DRF配置
  REST_FRAMEWORK = {
      "DEFAULT_VERSIONING_CLASS": "utils.version.MyVersion",
  }
  
  

• utils/version.py：自定义版本控制类的determine_version方法

  class MyVersion(object):
      """ 自定义的版本控制类 """
  
      def determine_version(self, request, *args, **kwargs):
          """
          版本号携带在过滤条件 url?version=v1
          :param request: 
          :param args: 
          :param kwargs: 
          :return: 版本号 给了request.version
          """
          version = request.query_params.get("version", "v1")
  
          return version
  
  

4.2 利用框架

• 提供了五种常用的版本配置类

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

• 如：settings.py

  # DRF配置
  REST_FRAMEWORK = {
      "DEFAULT_VERSIONING_CLASS": "rest_framework.versioning.QueryParameterVersioning",
      "DEFAULT_VERSION": "v1",
      "ALLOWED_VERSIONS": "v1, v2",
      "VERSION_PARAM": "version"
  }
