背景介绍:基于netcore2.2开发api接口程序，自定义了一个异常捕获中间件，用于捕获未经处理的异常以及状态码404、500等访问(设计的出发点就是，出现了非200的响应，我这边全部会进行处理成200，并返回固定格式的JSON格式数据)，并进行统一的信息返回。
返回的JSON实体定义如下:
中间件部分代码如下所示:
异常截图如下:
文字信息:fail: Microsoft.AspNetCore.Server.Kestrel[13]
Connection id "0HLVT9ADLSD7M", Request id "0HLVT9ADLSD7M:00000001": An unhandled exception was thrown by the application.
System.ObjectDisposedException: Cannot access a closed Stream.

以上就是本人遇到的问题，目前还未找到解决方案，故发此博文寻求众开发大佬的帮助，先提前感谢!欢迎大家留言支招!
