json格式化时，添加自己自定义动作

pythonjson.py

import json
import datetime

# json格式化时自定义动作
class CJsonEncoder(json.JSONEncoder):
    def default(self,obj):
        if isinstance(obj,datetime.datetime):
            return obj.strftime('%Y-%m-%d %H:%M:%S')
        elif isinstance(obj,datetime.date):
            return obj.strftime('%Y-%m-%d')
        else:
            return json.JSONEncoder.default(self,obj)

if __name__ == '__main__':
    noticList = [{'1':1,'2':2,'d':datetime.datetime.now()}]
    print(json.dumps(noticList, cls=CJsonEncoder))
    
    # 输出：
    #[{"d": "2018-06-15 16:47:45", "2": 2, "1": 1}]
