默认值应在服务器端处理，因为服务器不应总是假定客户端发送的HTTP请求100%符合规范。

如果您尝试使用架构发送默认数据，我认为这可以帮助您：

definitions:
 Pet:
  type: object
  default:
    name: xxxx
    birthday: xxxx 
  properties:
    name:
      type: string
    birthday:
      type: integer
      format: int32

好的，我可以在服务器端处理，但是，Swagger中的默认值有什么用呢？您也可以使用Swagger规范生成服务器存根，它应该正确处理规范中规定的默认值。
