Python将时间序列化为json

以下示例

将

python

中的数据结构：

字符串，数字，时间，列表，字典都序列化为json数据

import json
from datetime import datetime
from datetime import date

info = {
    "name": "Tom",
    "age": 18,
    "time": datetime.now(),
    'hobbies': ['music', 'read', 'dancing'],
    'addr': {
        'country': 'China',
        'city': 'shanghai'
    }
}

class MyJsonEncoder(json.JSONEncoder):
    def default(self, obj):
        if isinstance(obj, datetime):
            return obj.strftime('%Y-%m-%d %H:%M:%S')
        elif isinstance(obj, date):
            return obj.strftime('%Y-%m-%d')
        else:
            return json.JSONEncoder.default(self, obj)

json_info=json.dumps(info, cls=MyJsonEncoder)
print(json_info)

"""
{
    "name": "Tom", 
    "age": 18, 
    "time": "2019-09-14 21:47:29", 
    "hobbies": ["music", "read", "dancing"], 
    "addr": {"country": "China", "city": "shanghai"}
}
"""
