python person = Person(name="Alice", age=30) 使用marshmallow 的Schema 将dataclass 实例序列化为 JSON 字符串: python json_str = PersonSchema().dumps(person) print(json_str) # 输出: {"name": "Alice", "age": 30} 这三种方法都可以将 dataclass 实例转换为 JSON 字符串,根据你的具体需求...

1 【背景】 在使用json格式保存数据时,经常会遇到xxx is not JSONserializable,也就是无法序列化某些对象格式。 业务逻辑中定义一个class A, A其中某个参数为另一个classB。json.dumps(obj)后会报错无法序列化。 比如在和C#交互数据时,由于传输的数据是str格式,会面临此问题。 可以自定义class继承json.JSONEncode...

dataclasses_json is a library that provides JSON capabilities to python's data classes. I noticed that overriding to_dict method has no effect. Here's an example:@dataclass_json @dataclass class Message2: message: str weight: int def to_dict(self, encode_json=False)...
Converting dataclasses to JSON in Python involves a nuanced understanding of Python classes and the crucial aspect of JSON serialization. To initiate this process, we explore the basics using the native json module, subsequently delving into advanced techniques with third-party libraries like dataclasse...
