我有一个基本的词典如下:

sample = {}
sample['title'] = "String"
sample['somedate'] = somedatetimehere

当我尝试做的时候,jsonify(sample)我得到:

TypeError: datetime.datetime(2012, 8, 8, 21, 46, 24, 862000) is not JSON serializable

我能做些什么,以便我的字典样本可以克服上述错误？

注意:虽然它可能不相关,但字典是从mongodb中检索记录生成的,当我打印输出时str(sample['somedate']),输出是2012-08-08 21:46:24.862000.

我跟着如何在python中克服"datetime.datetime而不是JSON serializable"？但这没有帮助

我试过这段代码

>>> import datetime
>>> a =datetime.date(2014, 4, 25)
>>> from bson import json_util
>>> b = json.dumps(a,default = json_util.default)
