Python中序列化一般有两种方式:pickle模块和json模块, 前者是Python特有的格式, 后者是json通用的格式. 相较于PHP反序列化灵活多样的利用方式, 例如POP链构造,Phar反序列化, 原生类反序列化以及字符逃逸等.Python相对而言没有PHP那么灵活, 关于反序列化漏洞主要涉及这么几个概念:pickle,pvm,__reduce__魔术方法. ...
This error occurs when json.dumps(json_data, ensure_ascii=False) is configured in the Python script. The following figure shows the error.By default, DataArts Studio uses
使用python分离出一串文本,因为是看起来像整数,结果json转换时发生异常:TypeError: Object of type Decimal is not JSON serializable msgInfo={"uid":3232324232} json.dumps(msgInfo, ensure_ascii=False) 原因: decimal格式不能被json.dumps正确处理。json.dumps函数发现字典里面有 Decimal类型的数据,无法JSON serial...
