从python对象创建序列，包括它的@属性

class MyClass:
    def __init__(self):
        self.@property1 = "value1"
        self.@property2 = "value2"

obj = MyClass()

import json

class MyClassEncoder(json.JSONEncoder):
    def default(self, obj):
        if isinstance(obj, MyClass):
            return {f'_{k.lstrip("@")}': v for k, v in obj.__dict__.items()}
        return super().default(obj)

def myclass_decoder(dct):
    obj = MyClass()
    for k, v in dct.items():
        setattr(obj, f'@{k}', v)
    return obj

# 序列化
serialized = json.dumps(obj, cls=MyClassEncoder)
print(serialized)

# 反序列化
deserialized = json.loads(serialized, object_hook=myclass_decoder)
print(deserialized.@property1)  # 输出: value1

import pickle

# 序列化
serialized = pickle.dumps(obj)

# 反序列化
deserialized = pickle.loads(serialized)
print(deserialized.@property1)  # 输出: value1
