转换json时出现了

TypeError: datetime.datetime(2015, 9, 11, 18, 12, 7, 679000) is not JSON serializable

因为不能解析datetime格式

解决方案:

# coding: utf-8import jsonimport simplejsonimport functoolsfrom datetime import date, datetimedef date_encoder(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 super().default(self, obj)class JsonDateEncoder(json.JSONEncoder):    def default(self, obj):        return date_encoder(obj)class SimplejsonDateEncoder(simplejson.JSONEncoder):    def default(self, obj):        return date_encoder(obj)if __name__ == '__main__':    dic = {        'id': 1,        'name': 'yehun',        'date': datetime.now()    }    json_func = functools.partial(json.dumps, cls=JsonDateEncoder)    print json_func(dic)    simplejson_func = functools.partial(simplejson.dumps, cls=SimplejsonDateEncoder)    print simplejson_func(dic)
