Posted 2021-11-23 shenjunhui6

import json
from datetime import datetime, date


class MyJson(json.JSONEncoder):
    def default(self, o):
        if isinstance(o, datetime):
            return o.strftime(‘%Y-%m-%d %X‘)
        elif isinstance(o, date):
            return o.strftime(‘%Y-%m-%d‘)
        else:
            super().default(self, o)


date_time = {‘day1‘: datetime.today(), ‘day2‘: date.today()}

print(json.dumps(date_time, cls=MyJson))

json序列化
