我有类似的问题,但是我没有调用json.dump函数。 因此,要使MyClass JSON可序列化而不给json.dump提供自定义编码器,您必须Monkey修补json编码器。 首先在模块my_module中创建编码器: 12345678910111213141516171819 import json class JSONEncoder(json.JSONEncoder): """To make MyClass JSON serializable you have ...
Make a Python Class JSON serializable The Python built-in json module can only handle Python primitives types that have a direct JSON equivalent (e.g., dictionary, lists, strings, Numbers, None, etc.). So when we try to serialize custom class instance into JSON, we receive a type error....
Python的内置 json 模块只能处理具有直接 JSON 等价物的Python 基元类型(例如,str、int、float、bool、None等)。 如果Python 字典包含一个自定义 Python 对象作为键之一,并且如果我们尝试将其转换为 JSON 格式,你将得到一个 TypeError 即Object of type "Your Class" is not JSON serializable....

Separate the Lambda handler from your core logic.This allows you to make a more unit-testable function. For example, in Python, this may look like: deflambda_handler(event, context): foo=event['foo'] bar =event['bar'] result = my_lambda_function(foo, bar)defmy_lambda_function(foo, ...
