Django封装交互接口代码

我就废话不多说了，大家还是直接看代码吧~

from django.http import JsonResponse
 
class HttpCode(object):
 ok = 200
 paramserror = 400
 unantu = 401
 methoderror = 405
 servererror = 500
 
def ok():
 return result()
 
def result(code=HttpCode.ok, message='', data=None, kwargs=None):
 json_dict = {'code': code, 'message': message, 'data': data}
 if kwargs and isinstance(kwargs, dict) and kwargs.keys():
  json_dict.update(kwargs)
 return JsonResponse(json_dict)
 
def params_error(message='', data=None):
 return result(code=HttpCode.paramserror, message=message, data=data)
 
def unauth(message='', data=None):
 return result(code=HttpCode.unantu, message=message, data=data)
 
def method_error(message='', data=None):
 return result(code=HttpCode.methoderror, message=message, data=data)
 
def server_error(message='', data=None):
 return result(code=HttpCode.servererror, message=message, data=data)

补充知识：python部署galery集群
