python中这个错误的原因是json.dumps无法对字典中的datetime时间格式数据进行转化,dumps的原功能是将dict转化为str格式,不支持转化时间,所以需要将json类部分内容重新改写,来处理这种特殊日期格式。
例如字典dic:
dic={'name':'jack', 'create_time': datetime.datetime(2019, 3, 19, 10, 6, 6)}
直接json.dumps(dic)会报如下错误:
方法重写后代码如下:
import datetime
import json
class DateEncoder(json.JSONEncoder):
def default(self, obj):
if isinstance(obj,datetime.datetime):
return obj.strftime("%Y-%m-%d %H:%M:%S")
else:
return json.JSONEncoder.default(self,obj)
dic={'name':'jack', 'create_time': datetime.datetime(2019, 3, 19, 10, 6, 6)}
print(json.dumps(dic,cls=DateEncoder))
现在输出结果就不会报错了:
