我不知道是什么触发了这个错误。我不知道为什么我一直收到这个错误。我已经更改了部分代码，但仍然出现此错误。我已经尝试修复它 2 天了。

我在python中序列化和反序列化JSON的一个简单方法如下。
这可能不是最好的方法，但作为新手，在 python，它帮助我完成工作。
import json
import requests
class UserModel:
GET_USER_URL = "https://jsonplaceholder.typicode.com/todos/1"
#{'userId': 1, 'id': 1, 'title': 'delectus aut autem', 'completed': False}
def __init__(self) -> None:
pass
def __init__(self, userId, id, title, completed):
self.userId = userId
self.id = id
self.title = title
self.completed = completed
def getUser():
response = requests.get(UserModel.GET_USER_URL)
res = response.json()
print("Response\n",res)
#dict_obj = json.loads(res)
#print("Type of dict_obj", type(res))
return json.dumps(res, indent=4, cls=UserEndoder)
# subclass
class UserEndoder(json.JSONEncoder):
#I removed self as it was causing:
#TypeError: JSONEncoder.encode() missing 1 required positional argument: 'o'
def default(o):#I
return o.__dict__
示例用法
userModel = UserModel.getUser()
print("Serialized results:\n",userModel)
userModel = UserModel(123, 321, "test title", True)
print("Deserialized:\n",UserEndoder.default(userModel))
祝你编码愉快！！！
