如何将类中的方法添加到JSON对象

class MyClass:
    def my_method(self):
        return "This is a method in MyClass"

import json

my_object = {
    "name": "My Object",
    "class_instance": MyClass()
}

json_string = json.dumps(my_object)

with open("my_object.json", "w") as file:
    json.dump(my_object, file)
