from json import dumps

from flask import Response

from flask_api import status

from protocol.errors_pb2 import *





class ErrorResponse(Response):

    def __init__(self, err_code, err_msg=''):

        result = dumps(dict(code=err_code, msg=err_msg))

        Response.__init__(self, result, mimetype='application/json')





class JSONResponse(Response):

    def __init__(self, data, msg=''):

        result = dumps(dict(data=data, code=Error_None, msg=msg))

        Response.__init__(self, result, mimetype='application/json')





class UnauthorizedResponse(Response):

    def __init__(self):

        data = dumps(dict(msg="need login", code=Error_NeedLogin, data=None))

        Response.__init__(self, data, mimetype='application/json', status=status.HTTP_401_UNAUTHORIZED)

注意：一定要使用json.dumps来转换最后的结果
