python3运行报错：TypeError: Object of type 'type' is not JSON serializable解决方法

[Han-Gang]

我们自定义一个类试试

class User(object):
   def __init__(self, name):
        self.name = name

class UserEncoder(json.JSONEncoder):
    def default(self, obj):
        if isinstance(obj, User):
            return obj.name
        return json.JSONEncoder.default(self, obj)

json_2 = {'user':User('orangle')}
print json.dumps(json_2, cls=UserEncoder)

''' PS D:\code\python\python_abc> python .\json_extention.py {"date": "2014-03-16 14:01:46.738000", "num": 1112} {"user": "orangle"}
