【后端开发】flask响应体接口标准化

 基本设想：

{ "code":200, "msg":"成功", "data":null }

其中code代表响应状态码，msg传递结果信息或异常信息，data用于返回响应数据。

from flask import jsonify


# 响应代码类：
class ResponseCode(object):
    SUCCESS = 200  # 成功
    FAIL = -1  # 失败
    NOT_FOUND = 404  # 未找到相关信息
    ERROR = 500

# 响应体类：
class ResBody(object):
    """
   封装响应体
   """

    def __init__(self, data={}, code=ResponseCode.SUCCESS,
                 msg="success"):
        self._data = data

        self._code = code

    def update(self, code=None, data=None, msg=None):

        if code is not None:
            self._code = code
        if data is not None:

        temp["code"] = temp.pop("_code")
        return jsonify(temp)
